84 AVENT HORIZON By Pete Putman, CTS

WAVELENGTH Some months ago, I wrote an editorial arguing that the “convergence” we’ve seen between audiovisual technology and IT is paralleled by an intermixing of industr y trade shows, which, at one time, were much easier to delineate. That editorial came to mind during the NAMM Show—the annual gathering of the music products industr y—last month. Having covered the musical instrument space for six years as Editor of sister publication The Music & Sound Retailer, I distinctly remember the NAMM Shows of the early 2010s, which were heavily trafficked by mom-and-pop music shops and where guitars, drums, keyboards, instrument amps and mid-level speakers stretched from wall to wall. Fast-for warding to the present, the show has evolved markedly. As I traversed ACC North at the Anaheim Convention Center, the selection of commercial audio products on display called to mind the west coast AES shows of the past, prior to the association hitching its wagon to NAB Show New York and deciding to maintain an annual presence at the Jacob Javits Convention

Center. Developers of ever ything from line-array speakers, to power amplifiers, to audio networking products, to immersive audio systems lined the aisles. And there were AV integrators there, too— perhaps those whose travel budgets preclude a trip to New York NY each year. That’s not to mention the most obvious tie-in, of course: the AES@NAMM Pro Sound Symposium: Live & Studio 2019, which was held concurrently. One interesting wrinkle for this year’s NAMM Show trip was that it was simultaneous with the infamous government shutdown that left TSA agents, air-traffic controllers and many others without pay. Fortunately, my flights were unaffected; the whole situation, however, drew attention to the sometimes-unpredictable nature of the federal bureaucracy. And government is top of mind this month, as February always brings Sound & Communications’ “Government Facilities & Public Works” theme issue. Interestingly, all the projects we feature this month—Riverside CA’s East County EOC, Berkeley CA’s Downtown Berkeley BART Plaza and Aus-

tin TX’s Austin-Bergstrom International Airport—represent primarily state and local investments, rather than federal expenditures. Perhaps, away from the national spotlight, Dan Ferrisi local government is better able to govern—and to invest. Delving deeper into this month’s issue, we have an interesting dispatch from frequent contributor Stephen O. Frazier, who discusses the growing prevalence of hearing-assistance systems in airports around the world. Plus, NSCA presents the first in its quarterly series of features, this one centered on strategies to build your company’s talent pipeline. Twenty-nineteen has started with a flurr y of activity, both in our industr y and across the world. Hang on for what’s next!

What’s All The Noise About? Assessing noise in rooms and AV facilities. By Peter Mapp, PhD, FASA, FAES


ne of the most annoying situations in which to find yourself is to be in a noisy room when trying to sleep, concentrate, communicate with colleagues, listen to a lecture or set up an audio system. Noise is a killer of intelligibility, and it can be very distracting or annoying—particularly if it contains a tonal element. We are surrounded by noise all the time, especially in AV-related situations, with noise being generated not only by the equipment itself but also by, or within, the room or venue. Typical culprits are fan-cooled devices— projectors, computers, and some audio amplifiers and processors—together with noise from the air-conditioning system or noise breaking in from external plants, equipment or people. Some noise can be a good thing, because it can mask other distracting sounds and provide us with some stimulus. However, if there is too much noise, it can be distracting or even stressful, degrading communication and speech intelligibility. Those are vital pillars of the learning process, particularly in schools and colleges, or commercially in seminars, meeting rooms, etc. So how much noise is too much, and how do we assess a potential noise issue? First, we have to have a method of measuring and rating a noise. The simplest way is just to measure the “A weighted” sound level, or, more simply, the dBA reading as found on nearly all sound level meters. The “A” weighting curve attempts to adjust the measured sound pressure level (SPL) so that it better agrees with subjective impressions. It does so by attenuating the

lower-frequency sounds, particularly below 500Hz, where our hearing at low to moderate sound levels is less acute. It also slightly emphasizes sound at 2kHz, where our hearing is most sensitive. The “A” weighting cur ve is shown in Figure 1. Also shown is the “C” weighting cur ve. The “C” weighting was originally introduced to improve the match of a physical measurement of a sound to our subjective impression of its loudness (or noisiness) at higher sound levels. As can be seen, it has a much flatter response, being just -4dB down at 125Hz, as opposed to the -16dB of the “A” weighting. It is also approximately -3dB down at 8kHz, as compared to -1dB of the “A” weighting. Nevertheless, dBA has become the universally adopted method for rating virtually all sounds. The problem with this single-number measure is that it tells you nothing about the character or spectrum of a sound. The latter property is particularly important when it comes to reducing the level of a noise because different materials attenuate (or absorb) sound in dissimilar ways; as such, they might be more or less effective depending on their (and the unwanted sound’s) frequency characteristics. These days, carr ying out an octave band or 1/3 octave band spectral analysis is extremely easy; however, that was not so many years ago. Formerly, each band had to be separately and sequentially measured using an additional filter set. Therefore, 1/3 octave noise measurements were comparatively rare, particularly because one octave resolution can usually provide the required information. Figure 2, for example, shows a 1/1 (one octave) analysis of the fan in my desktop computer at my normal working position. The octave band analysis is on the left-hand side of the figure (blue bars), and it shows the maximum noise to be located in the 250Hz band (47dB); however, the 500Hz band is not far behind, being just 2dB lower at 45dB. The overall “A weighted” SPL is 45dBA,

Figure 6: NC rating of computer noise.

whereas the “C weighted” value is 51dBC and the unweighted value is 55dBZ. Due to the nature, spectrum and steadiness of the fan noise, I do not find it annoying when working. It does not affect the clarity or intelligibility of communication, and it’s not annoying—but I wouldn’t want it to be any louder. Equally, the noise is not all around me, but, rather, comes from a specific direction and from a specific and known piece of equipment. The noise, however, would be completely unacceptable in my listening room. Indeed, it doesn’t take much for a similar noise to be annoying. The noise of a local uninterruptable power supply (UPS) that I wanted to use is completely unacceptable, despite only being a few dB louder. Figure 3 compares the noise generated (separately) by the two pieces of equipment. To put these numbers in context, 35dBA is the recommended maximum noise level for school classrooms; 35dBA to 40dBA is recommended for boardrooms, conference rooms and courtrooms; and 35dBA to 45dBA is suitable for lecture theaters, assembly halls and similar settings. Ideally, churches would be a little less at 35dBA to 40dBA. Although a useful indicator, a dBA reading is not really sophisticated enough to set a criterion or make an assessment. That fact was recognized many years ago, particularly with respect to the noise from air-conditioning systems and mechanical ser vices. Thus, in 1971, a set of cur ves (weightings) was developed specifically for such noise, based on an octave band spectral analysis of the noise. These were the Noise Criteria (NC) and Preferred Noise Criteria (PNC) cur ves. The NC cur ves range from values of 15 to 70 over the frequency range of 63Hz to 8kHz. I have plotted a set of NC cur ves in Figure 4, but, for clarity, I have omitted those above 45. The cur ves are nominally set at 5dB intervals and crudely follow our nominal hearing sensitivity. The corresponding

PNC cur ves are shown in Figure 5. They have a steeper gradient at low to mid frequencies, and they were created to provide preferred noise spectrum shape in an attempt to reduce the intrusiveness of air-conditioning and mechanical-ser vices noise. For comparison, I have plotted my computer noise on the NC grid, as shown in Figure 6;

this shows it to be the equivalent of NC 41, although, strictly speaking, this should be taken to the nearest value divisible by five. (The NC value is taken by plotting the octave band spectrum onto the NC cur ve background template and then reading the highest-value line with which it (continued on page 76)

IoT Management

By Mike Brandofino Yorktel


remember it vividly…. I was sitting in the audience at a Microsoft Conference and listening to Bill Gates talk about the technology to come. He started to talk about a time when your refrigerator would be connected to a network, and it’d be able to keep track of what you had to buy. This was around 2003, and, as a CTO, I was thinking, “We are still using dial up for video. How are we ever going to have the ability to connect ever yday devices—and why on earth would we want to?” Although the term was not yet coined, what Bill was talking about is now called the Internet of Things (IoT). Fast-for ward to last year at InfoComm, where I was moderating a panel on the impact of IoT on managed ser vices. It is estimated that the number of IoT devices in operational deployments will exceed 50 billion by 2020, and, yes, that does include smart refrigerators. This alarming growth of connected devices is creating a challenge for anyone who is involved in deploying and managing technology, and it creates some new challenges for managed ser vice providers (MSPs). The variety of IoT devices is truly staggering. Walk down the street and you will see IoT devices ever ywhere you look—parking meters, city bikes, traffic cameras and much more. Walk down the hall in any office building and—setting aside the traditional computers, printers and other office equipment—you now have connected thermostats, lighting and vending machines. The proliferation of IoT devices introduces a scalability challenge never previously experienced, as organizations have to manage fleets of devices. The variety of IoT devices and the

18 Sound & Communications February 2019

The time is right for managed service providers to bring value. large scale of deployments create a security challenge. Ever y connected device has the potential to be an entr y point for cyberattacks. This is especially true for organizations that don’t have a mature security strategy or dedicated resources to manage security. Something as simple as leaving the default admin password when devices are installed can create an access point onto your company’s networks. I recently met with a city government office dealing with a hacking incident; it turned out to be via the heating systems’ control unit. Finally, all these devices produce a prodigious amount of data, with only a small fraction being adequately captured and analyzed. Big Data is a top-10 topic for virtually every CIO of a medium to large company, and a topic that they lack the internal resources to address. Given the scope of the challenges, as well as the limited resources with the skills to manage them, it is logical that MSPs can play a role in helping organizations address their IoT challenges. The key is to understand the role of MSPs, as well as how they should adapt their ser vices. A few areas where an MSP can bring value are as follows: • Device as a Ser vice (DaaS) is a term that we will be hearing more about in the coming years. We are used to it in the mobile-phone space, but, until recently, the model simply wasn’t viable for other devices. That is quickly changing. Offering customers an option where a single ser vice provider can handle all the logistics of staging, imaging and deploying devices as a ser vice will enable organizations to scale according to their needs, without requiring the resources to be in house. • Security Operations Center (SOC) Ser vices is the concept of having an external organization monitor the connected devices and having security experts evaluate alerts and threats. By filtering the large amount of data produced by the security monitoring, the SOC can focus on providing internal IT organizations only information that is actionable, along with suggestions for remediation. • Monitoring On Many Levels: Connected devices can provide many data points, and ser vice providers must be able to monitor and capture the information on many levels. That includes connectivity and operational status, performance and experience statistics, vulnerability and risk status, as well as utilization data. • Big Data Storage and Analytics: The data captured can provide valuable insights into how the device is performing and how it is being used. However, most organizations don’t have the capacity to store large quantities of data and efficiently run reports to analyze it. Ser vice providers will have to be able to provide this type of ser vice to help organizations harness the potential of IoT devices and maximize their return on investment (ROI). We are at an inflection point where MSPs must adapt to address new challenges resulting from our connected world. The timing is right, as customers are now comfortable outsourcing some of these core capabilities, and they’re desperate for help.




Tech For Ministry, Part 1 My top seven equipment list for 2019. By David Lee Jr., PhD Lee Communication Inc.


believe that this year will be a prosperous one for our industr y. In 2018, I spoke with hundreds of pastors and worship leaders. Those leaders indicated that they will continue to replace outdated technologies used to enhance the worship experience, and they will purchase technologies that enable them to organize and process data far more efficiently. The gear that these leaders desire—and plan to acquire— spans a vast range of audio and video categories. However, seven items are most desired by these leaders. They are the following: video projectors, sound-reinforcement equipment (loudspeakers), digital audio mixing boards, video cameras, video production gear for image magnification (IMAG) and live streaming, moving lights and in-ear monitor systems (IEMs). Video projectors remain the mostdesired technology among houses of worship (HoWs). Why? Because we are now an image-driven society—but you knew that already! There are additional reasons why video projection continues to stay on the “most wanted” list. The overarching reason is that video displays are used in nearly ever y setting. They are used in nurseries, worship spaces where children gather, worship spaces where teenagers gather, social spaces and, of course, the main sanctuar y setting. Historically, a hymnal was used when the congregation engaged in corporate worship. In today’s contemporar y HoWs, however, there is no book that contains the current (and everchanging) songs. Thus, video projec-

tion is used to display the lyrics. In addition, think back to when congregants looked down to read song lyrics. With the use of video-projection systems, the entire congregation can look up and see each other as they sing. That creates a shared experience and a sense of community for the congregants—something that is strongly desired by the majority of those attending. An unintended positive consequence of displaying the lyrics is that, in English-speaking settings, the lyrics being displayed in English helps people who are learning the language to participate in corporate worship. Obviously, in a global context, no matter the primary language of the lyrics, it serves the people who speak the language and those who are learning it. Also, as image resolution continues to improve, there will also be a continued desire to upgrade to the next level of projection or display technology. Let’s next talk about digital audio mixing boards. I like analog. I also like digital. The interactions I have had with HoW leaders paint a clear picture: They have, or they want, a digital audio mixing board. They are not concerned about techie arguments relating to analog versus digital. Rather, they are driven to acquire this technology by myth and by the practical reality that ver y good digital boards are now within the financial reach of even small HoWs. In fact, I am writing this article while in a ver y small town in Alabama, working to install a ver y popular (and affordable) digital board and a small mini-array system for a HoW that has about 100 members. As many of you have probably experienced, or perhaps used as a sales tactic, the feature that sells the digital console is the “recall” system. Small HoWs typically rely on volunteers to manage the audio board during ser vices. Often, an “inventive” volunteer will alter settings that then cause near-catastrophic results that can nearly destroy the worship experience. The ability to set up a reasonably strong mix with a digital console, and then save that setup, provides a quick solution for a small HoW; indeed, it’s actually a ver y strong selling point for us to use with HoWs from small to mega-sized. After all, medium, large and mega-sized HoWs also value the ability to set up mixes, save them and then recall the setup (and snippets) that apply to the different worship experiences they host each week. For example, at 8am, a HoW hosts a traditional worship experience for older adults who desire a simple experience that uses a piano or an organ (or both), and perhaps a few microphones. At 9:45am, the HoW hosts a worship ser vice that blends traditional music with contemporar y “lite” music. Then, at 11:30am, the HoW hosts a contemporar y ser vice that has 30-plus inputs and includes a large drum kit, guitars, keyboards, bass guitar, multiple wireless mics, numerous monitor mixes and so on. A digital console allows the operators to save a setup for each ser vice, and then recall the appropriate setting for each ser vice. Those two technologies are ver y high on the “must get” list for the leaders to whom I have spoken. My list is most likely relevant to your own, and to the lists of (continued on page 76)

THE COMMISH In the AV industry, the end users are typically represented by two separate, yet equally important, groups: the designers, who specify the systems, and the integrators who install them. My company acts as a third party to commission these systems. These are our stories.

Contractual Lines Of Demarcation Who does what? By James Maltese, CTS-D, CTS-I, CQD, CQT Audio Visual Resources, Inc. AV9000 Checklist Item Under Test: 5.0 – Convene a short Pre-Audit Meeting of the individuals involved with the audit. Review ever yone’s roles, the conduct expected, discuss “what ifs” and issues that may come up, so that immediate action can take place without further discussions or delays. Reasoning: The number of people involved in projects is ever increasing. Due to the vast number of skills required to complete an install, the industr y is moving toward specialists, rather than jacks-of-all-trades. As such, a project might have a designer, a cable worker to pull cables, technicians to terminate and dress cables into a rack, a control system programmer, a DSP audio engineer, a third-party commissioning team, etc. With so many cooks in the kitchen, it is ver y important to understand not only the role for which you are responsible, but also where the line of demarcation is between you and the other specialists. If those lines become blurred, the tasks found in the middle might be done twice—or not at all. Cross-discipline understanding and communication is essential for successful projects that have so many players. The Stor y: I had the privilege of taking part in the Wood Badge leadership course hosted by my local Boy Scouts of America (BSA) Council. It was life changing. I met so many incredible people. I learned a tremendous amount about myself and about how to lead others. I had a memorable, fantastic time. And, now, I’m “working my ticket” and still having a blast. I love it! One thing about the course that struck me was how many staff volun22 Sound & Communications February 2019

teers were required to pull off both three-day weekends of the course. We had the Scoutmaster and Senior Patrol Leader (with their assistants), who basically ran the course. We had a threedeep Logistics Crew that handled all the setup and breakdown of events. We had Troop Guides to lead our patrols. We had a Troop Scribe to put the daily newsletter together. We had four-deep Quartermasters to keep all of us fed. We even had Naturally, a Wood Badge leadership course got the a volunteer to run the author thinking about managing AV projects. Wood Badge Shop, so we all could get our souvenirs. In short, it was a well-oiled machine. Each person understood his or her role, and the Course Director conducted the entire orchestra of staff. There were meetings before the trainings to make sure ever yone understood the overall mission, as well as their individual goals. The staff met several days before the actual training to do some dr y runs to make sure ever ything went smoothly. During the course, if something happened (as it always does), it was usually addressed by the appropriate staff member before the attendees had even noticed. I was blown away! Naturally, this got me thinking about managing AV projects. Even though third-party AV commissioning is the bee’s knees, it is not incorporated into ever y single AV project out there. When the impressively intelligent client makes the wise decision to use a third party (like us) to commission its systems, some of the players are not quite sure what our role is. They know we are going to inspect levels on the DSP mixer, but they confuse the inspection with actually creating the site files. We have walked onto several sites with blank mixers, and, upon asking about their inoperative status, the tech told us, “Some other commissioning company is handling that.” We see the same stor y with setting up EDID management in matrix switchers. We find that switchers have the default settings loaded, despite the contract clearly calling for a different EDID solution. When asked why the settings are still set at the defaults, the tech again replied, “Oh, I think another company is handling that.” There is misunderstanding between, and a lack of communication among, the project

players, and it consistently adds time and money to projects. That’s not to mention that it adds to the frustration of those working to get it done! When so many different people are involved in a project, it is ver y important to make sure ever yone knows what he or she is responsible for, as well as the most efficient way to interface his or her piece with the rest of the team. This is less of an issue when one “general AV contractor” hires subcontractors to fill in the gaps, because the contractor will handle the coordination better when it holds the main contract. The big problem arises when several of the players—for example, the AV installer, the control system programmer, the “audio guy” and the third-party commissioning team—are contracted directly to the client. With enterprise clients, this is becoming more common. And, if the client doesn’t have a strong construction/project manager, no one will coordinate these AV vendors until problems start to materialize. The moral of the stor y is this: Project management is key to a project’s success. It is entirely possible, in this world of specialists, to take part in a project with no one steering the ship. If you find yourself in one of these rudderless projects, it would make financial and spiritual sense to offer project-management ser vices to your client, thus helping the client avoid potential problems. It will also make your company stand out as one that respects the effort it takes to pull off a successful project. Proper project management can be difficult, time-consuming and painstaking in its details…and it’s crucial to a successful project. They say it takes a village to raise a child. Well, it also takes a village to support a project. A ton of information must flow back and forth between all members of the project team, and someone has to make sure that happens. Holding a project

meeting to iron out all those misunderstandings before the project kicks off can go a long way toward avoiding problems down the road. The Wood Badge course changed the way I see leadership, as well as how I think projects have to be managed. It

might be difficult to get the processes set up, sell it to the client and staff it, but a project that is well run is a thing of beauty. Maybe we should start handing out merit badges to get more people to commit to it. It worked for ol’ Baden-Powell.


Who Owns The Code?, Part 2 Concluding the discussion that we began in November. By Douglas Kleeger, CTS-D, DMC-E/S, XTP-E, KCD


hanks for all the feedback to my column from November, entitled “Who Owns The Code?” As you might have guessed, it drew comments from a number of different folks from several different areas of our industr y. As you might remember from Part 1, I discovered that there are still integration companies out there that do not turn over the programming code to the client at closeout—even after they are paid in full! I thought this issue, like others our industr y has encountered as we’ve matured, was one we had outgrown. However, it appears that this subject is not resolved, and there are those on both sides of the fence who have strong beliefs that their policies on this issue are fair and just.

Alexander Rosner Responds

As someone who has worked in this industr y for about 40 years, I want to give my two cents. But first, some background: I’ve sat in the chair of the Director of the Centers for Disease Control (CDC), setting up the conferencing system through which he consults with the President of the United States. I have pulled cable in sweltering attics; I’ve been in the air, hanging loudspeakers that weighed hundreds of pounds; I’ve produced hundreds of thousands of pages of documents, or perhaps even millions. And it’s fair to say millions of people have benefited from work with which I’ve been involved. That’s the background from which I’m opining. For ever y project, a list is made of

“Yes, we provide everything that we have on the job that would help the client in the future, in case he no longer loves us and wants someone else to service him. Seems like it’s the right thing to do, especially when I’ve been on the other side of things, coming into a job done by someone else!” Company Profile: Rosner Custom Sound, based in Long Island City NY, is a sound contracting firm that also does video.

Mike West Responds

what you have to do and what you need, right? And there’s always a line item for programming, correct? The company providing the ser vice does this for a profit. So, when the project is complete, all pieces of the project— from the cabling, to the devices, to the labor, to the intellectual property (design and programming)—are now, in my opinion, the property of the one who paid for it: the client! I just do not see, after the project is completed, how an integrator can withhold the uncompiled code and prevent clients from having someone else work on their system that they paid for! So, let’s turn to the responses I received. Over whelmingly, it appears

“It has been our practice for years to provide the code, audio files, drawings and serial numbers with the closeout documentation. It is our opinion that the customer owns the code the moment a PO is received. We also provide a one-year warranty for all systems we install.” Company Profile: Founded in 1997 in Huntsville AL, Quantum Technologies, Inc., is a professional audio, video, control and videoconference system design and integration firm, specializing in serving commercial, civilian and federal government customers for more than 20 years. West can be reached at

that turning over the uncompiled code at project closeout is what most integrators do, with a relatively small percentage not doing so. Although I did not get enough feedback to give an exact percentage, I would say, based on what I did receive, my best estimate is that 80 percent expressed support for giving access to the uncompiled code, whereas 20 percent stood opposed. (That is just an estimate, so please don’t hold me to it!) As far as audiovisual consultants go, I don’t personally know of any professional ones that do not provide in their specifications that the integrator is to turn over the uncompiled code to the client at project closeout. (Note: I added the adjective “professional” because there are some IT/security/acoustics consultants that dabble in AV, do a mediocre job and do not stipulate this in their specifications.) I researched this further by contacting Waveguide, one of the larger consulting firms in our industry. I spoke with Brad Beattie, the Director of Waveguide’s software-development division, Brainwave, to find out their policy on this. Waveguide provides consulting services as well as programming services, relieving the integrator from that portion of the project. With that context in mind, I was curious to learn the company’s stance. According to Beattie, yes, for projects for which Waveguide delivers the programming code, it does provide the uncompiled code at project closeout. Notable, however, is that the firm does require an agreement that the client will not use the code for a different project. That’s not dissimilar to what’s done with system design drawings, etc. In addition, Beattie said that, for projects where Waveguide does not provide the programming and it is covered under the specifications, it does require that the integrator turn over the uncompiled code to the owner at project closeout. Let’s examine some of the reasons given by integrators for why they do provide the uncompiled code to clients. Frankly, I heard the same thing over

and over again: They paid for it, it is their property and they own it. Not to give it to them is wrong, and it hurts our industr y! Another aspect brought to my attention is the possibility of the integrator going out of business, or even having a fire and losing all its data. How would clients get the code then, even if they agreed to pay separately for it? On the flip side, I did hear from those who don’t provide the uncompiled code at closeout. They cited low margins; they claimed it’s their intellectual property; and, most frequently, they said they wanted to prevent the client from going to someone else for service, changes, etc. I could go on forever talking about what’s wrong with those arguments, so I’ll leave things with this observation: Those I ad Platinum Tools 1/3 Square spoke to who provide the code at project

closeout had no issue with their attributed inclusion in this article; in fact, they welcomed being quoted. Those who do not provide the code, or who suggested charging extra for it, refused or never replied when I asked them if they could be quoted in this follow-up piece. Draw your own conclusions. The two sidebars are answers I received to my question, “Do you provide the uncompiled programming code at project closeout? Why or why not?” The contest winner (literally picked from a hat) is Alexander Rosner from Rosner Custom Sound. He will receive a can of Virginia Diner peanuts, as promised!

Energy Management: It’s Just Good Business AVIXA overhauls its standard for monitoring and controlling AV system power. By Ann Brigida, CTS, CStd AVIXA


ver y time AVIXA begins the task of authoring a standard, I ask myself if I really, really think it’s worth the effort, or if perhaps the topic is just a collective passion of a few people in the AV industr y. Nowadays, we vet ideas for new standards using a ver y detailed scorecard; however, when we first started out, the process was more reactive than proactive. So, I was a little dubious in 2012 when the topic of energy management rose to the top of the standard-development queue. To the credit of some ver y for ward-thinking leadership from the AVIXA Board of Directors, it turns out that creating a standard dealing with AV systems energy management was a solid choice. At that time in the AV industr y, the goal of our standards was relatively new: We were focusing on assessing the performance of a given system, as opposed to the technical capabilities. The impetus for the energymanagement standard came from the realization not only that saving energy was the right thing to do, but also that there was a potential return on investment (ROI) in energy management in the form of cost savings. The original standard included an ROI calculator, a 26 Sound & Communications February 2019

call for an “Energy Management Manager” to oversee the process and an education component that required specific training for specific job functions. The standard was comprehensive, and it had some passionate adopters. The problem? Adoption was slower than we had hoped. The range of reasons started with the general perception that AV systems didn’t draw enough power to warrant such attention; the list ended with the perception that the requirements were burdensome for small entities. Fast-for ward to today and AV is officially a business-critical —and, often, missioncritical—component of an organization’s enterprise technology roadmap. There’s a need to save both energy and money. And it just so happens that it’s time to reevaluate the original energy-management standard. What are the most important changes that have to be made? How will those changes help adoption? And, as usual, I asked myself if we were still on the right track. The answer was a resounding “yes!” ANSI/INFOCOMM 4:2012, Audiovisual Systems Energy Management is getting an overhaul. The revised standard provides a tiered approach to implementation; by contrast, the original took more of an “all or nothing” approach. The updated standard makes it possible for those who want to begin to manage their system’s energy use to show a basic level of conformance. For those who are more advanced in energymanagement practices and who really want to get a handle on an AV system’s usage, there is also a more rigorous set of conformance requirements. By lowering barriers to monitoring the energy that an AV system uses, the standard is applicable to more users than it previously was. With this new approach, virtually ever y audiovisual system is a candidate for energy-management implementation at a basic level. The hope is that adopters will start to manage AV systems’ energy simply, but then, as they’re able, conform to higher levels of the standard. The revised standard was open for public comment until the end of Januar y. As I write this, the task group is responding to comments, with plans to have the revision ready in time for InfoComm 2019 in Orlando FL. Keep an eye on for the updated version. David Barnett, CTS-D, is a Senior Consultant for The Sextant Group, Inc., and the moderator of the task group working on the standard’s revision. Barnett has the fortunate vantage point of being part of the first standard’s development, and he has

devoted countless hours to working with the task group to get this revision right. I asked him what motivated him to put in all this work, and I inquired about what makes it worthwhile. His response reflected his broad understanding of both the state of the industry and energy management’s role in the future: “There is now a greater realization that an AV system is not a self-contained end, but, rather, exists in a larger context of interconnected systems, many of which are intelligent in their own right. The flow and analysis of information is a critical component of the operation and management of these increasingly complex systems. The need to pay attention to energy consumption and management has become more apparent over the past decade. There is a solid business case to be made through cost savings by reducing power and heat loads, extending equipment life and operating more efficiently. Many building and electrical codes are now requiring that such systems be implemented. The trend toward sustainable architecture, ‘net-zero’ buildings, and an emphasis on renewable and regenerative energy sources has only increased over time, and it will continue to do so for the foreseeable future. Being part of this movement is rewarding beyond just the satisfaction of a job well done. It represents a positive contribution toward both the AV industry and the millions of people who use the systems we design and install every day. I worked on the original standard, and I found it to be a rewarding experience. A lot of really good work was done by a lot of very engaged and smart people. But, as often happens, the final document ended up with the ‘designed by committee’ vibe. I felt that, although it was a step in the right direction, the published document wasn’t as good as it might have been. It was an ambitious scope and very complicated to implement. Fast-forward to today, and this seemed like a great opportunity to produce an updated standard that represents a forward-thinking approach that would allow for greater adoption by the AV

community.” Were we on the right track? Absolutely. (Incidentally, there’s now even an association dedicated to energy management, with a third-party accredited certification for people who want to become an energy-management professional. Look up the Energy Management Association if you’re interested.)

We’re still planning an ROI calculator, which will be included in a Companion Guide to the revised energy-management standard for helping with implementation. But the bottom line? Adopt, adopt, adopt. It’s not only the right thing to do, either—such a standard also has the potential to save money.

Commercial AV, Live Production Trends Converge And AV-over-IP is driving it. By Brian Olson NewTek


he live production industr y has been on a journey for the past five or six years to find a suitable replacement for traditional baseband serial digital video. Driven by multiple factors, including the move to 4K ultra HD, industr y alliances and the Society of Motion Picture and Television Engineers (SMPTE) settled on an IP video standard known as SMPTE ST 2110 in late 2017. Two years prior to that, NDI (Network Device Interface), a free software-based IP video protocol that has seen wide adoption, was introduced. Now, with AV-over-IP (AVoIP), the commercial AV industr y is going through a similar IP evolution, with competing standards and many of the same issues, wants and needs that the live production community has.

Common Goals In moving to IP audio/video transport, both the commercial AV and the live production industries are looking for the same things: • high quality • low latency • scalability • flexibility • elimination of distance barriers • ability to use standard networking equipment • interoperability • cost-effectiveness Both industries want to be able to deliver more content, to more places, more effectively. IP infrastructure eliminates many of the barriers to delivering high-quality content in a ver y efficient manner. 28 Sound & Communications February 2019

Merging AV With Traditional IT Both live production and commercial AV see real benefits to breaking down the wall between the deliver y of audiovisual content and the deliver y of data over traditional IT networks. First, these networks already exist in many cases, and they’re supported by enough human resources in most organizations. Second, with the advent of streaming, the lines have already started to blur between the two disciplines. Not having to run separate pathways for the production and distribution of media also ser ves to streamline operations and keep costs down.

Finding The Right IP In the live production space, SMPTE 2110 is mostly being adopted by top-tier broadcasters and production studios that run in high-definition resolution. For 4K signals, ST 2110 requires 40GbE and 100GbE networks, limiting the use of this IP protocol in many places. NDI works on existing networks (1GbE and 10GbE), and it provides a pathway to IP for a larger section of the market, along with more efficient 4K transport. NDI is available royalty-free for all hardware and software developers as a software development kit (SDK). With AVoIP, the main competing standards are HDBaseT-IP and Software Defined Video over Ethernet (SDVoE). Each has its own set of benefits, and, as with their live production corollaries, one might be better suited to a project than the other is. It’s also possible that NDI might be the right choice for certain customers, becoming a crossover protocol between the traditional live production and commercial AV spaces.

Hardware vs. Software Approach SMPTE 2110 is a hardware-based IP protocol that must run on its own dedicated network. As mentioned earlier, these networks also have to be ver y fast. NDI is a software-based IP protocol that either runs on an x86 computer platform or runs as an ARM/FPGA implementation for embedded hardware operations. Due to high adoption rates over the past three years, native NDI input and output is supported by hundreds of software applications and a good number of video hardware products using only a network connection. HDBaseT-IP and SDVoE can also work on traditional networks, but they require separate hardware encoders and decoders to send and receive the AV streams. Of the two, HDBaseT-IP is the most interoperable, due to the widespread adoption of the original HDBaseT (HDMI-over-Cat5) technology.

Compression Is Not A Dirty Word When digital compression was first introduced for audio and video signals, it meant two things: less quality and more latency. That is no longer true, even though many purists in the live production and commercial AV businesses seem to believe (continued on page 76)

The Ultimate Command Center Ensuring audio system connectivity, functionality and flexibility. By Marjorie Daniel Shure Inc.


hen you think about government entities, the first thing that comes to mind is likely to be an impressive assembly or parliament hall that holds formal meetings, and which is equipped with sophisticated technology that can enable large groups of people to communicate in multiple languages. But what really marks the government sector is the huge variety within it— from the number and types of rooms, to how they are utilized, to the people who use technology within the spaces. Accommodating this variety of uses, while also maintaining a consistent and familiar user experience, can prove challenging when it comes to specifying and installing AV solutions. There are, therefore, a number of aspects to consider when making the decision to invest in AV. Government agencies are unique in several ways, not least of which are the long buying times and the often highly structured nature of the sector. That means there tends to be a lot of people involved in decision-making. In recent years, there has also been a trend toward increased transparency, with communities coming to expect to be informed of any decisions, as well as how they were made. With that in mind, it’s important to offer solutions that are able to meet these changing needs and that allow for new features that can make life ever easier for the user. At the same time, they also 30 Sound & Communications February 2019

must be suitable for people who, often, are not technically minded and who might not have AV/IT support on hand. Security, of course, is a major concern—with respect to both the audio within a room and how content will be streamed and stored. Finally, budgets will always have a major impact in the government sector; as a result, AV solutions that represent a long-term investment, offering robustness, reliability and a long lifespan, will be a sensible choice. Across the sector, wired solutions are most often chosen for chambers that require extensive voting, agendas, speech time and other management capabilities. However, many preliminar y meetings, working-group sessions and consultations take place before the gavel is ever lifted. These meetings range from formal to casual and might take place in historic hearing rooms or contemporar y multi-purpose spaces, or even at off-site locations. It is here that a wireless conference system can deliver the flexibility, reliability and connectivity that these situations require, all while preser ving the aesthetics of the building and minimizing any impact on its structure. Because rooms will be used by different numbers of people and for different purposes, flexible seating and scalable conferencing systems are sometimes a must. In situations such as those, consistency is key; government organizations benefit from a single system for any meeting or any room in the vicinity. These systems also have to be quick and easy to set up, because ever yone—from local political leaders, to event managers, to administrators—has to feel comfortable operating them. Wireless again ticks all the boxes here, and, as an added benefit, it is cable-free. That encourages natural interactions between participants, who are no longer held back by connections and who, instead, can move about and communicate without restraint. Of course, wireless systems also have to be robust. A common concern with wireless is that it won’t be as reliable as a wired setup. Because government agencies frequently have to deal with mission-critical events, it is essential that the solution chosen be able to cope with such demands. If your agency is hosting important speakers, for example, or if it’s inviting the community to share ideas and opinions, any system must work effectively ever y time. Because many government entities are situated in major cities, wireless systems must contend with crowded spectrum conditions. When specifying a system, it is important to look at not only its ability to select clear channels, but also its potential capacity to scan the spectrum to make sure there’s no potential interference—and, crucially, to adapt quickly if there is. When it comes to robustness, another aspect to consider is batter y life. Some meetings in the government sector can go on for long periods; thus, systems with long-

lasting batteries that can be monitored remotely will be beneficial. Organizers want to be sure there won’t be any interruptions to their meetings and events; therefore, it’s wise to look for technology that offers longevity and reliability. Because budgetar y constraints are hitting many agencies, it can be an unpopular move to be perceived as investing large amounts of money in what many communities would consider “nonessential ser vices.” With that in mind, it’s important to look at the cost-efficiency of any technology installed. Not only will robust and reliable technology last for many more years as compared to less reliable systems, but user uptake also will be higher because of a consistent user experience that aids meetings, not hinders them. Moreover, tech support callouts will be minimized when technology just works. The sheer variety of use cases in government entities means that connectivity is another key concern. For example, in addition to a wireless conference system, additional wireless microphones might be required if there is a large town-hall meeting, or if the public is invited to an event. In such cases, microphones will have to be available for audience members to ask questions, or for a presenter to comment on charts or slides. In instances like these, it’s essential for the system to be compatible with the microphones. Similarly, government organizations are increasingly requesting the ability to record sessions and stream meetings to their communities. Any system, therefore, will have to connect easily to the videoconferencing setup and the recording/streaming equipment. Although many government proceedings are public, there are also closeddoor sessions that often deal with confidential and sensitive information. That means the wireless signal must be encr ypted to prevent eavesdropping by those outside the meeting room. I’d also advise keeping up with software updates to ensure that systems operate

at their optimum level for longer, while also allowing users to benefit from any additional features introduced. Like many other sectors, government agencies are facing a number of challenges related to ensuring their employees can communicate and make effective decisions. The often mission-critical status of this work, alongside the need

to be transparent in some cases, yet private in others, is an added element to consider when investing in technology. Being able to trust that an installed wireless system is reliable, flexible, robust and secure can be a huge benefit in aiding decision-making, encouraging interaction and offering long-term solutions to meet user needs.

Quieter Is Healthier

Sound absorption can be a critical component of promoting wellness.

By John Calder Acoustical Surfaces


ospitals have become modern mar vels of medical science, mechanical engineering and computerization. They’ve achieved this to such a degree that many patients today complain only about the quality of the food or the “institutional” beige wallpaper. As hospitals and medical centers roll out the latest in groundbreaking science, so, too, do they make continuous improvements below the surface; examples include streamlining patient admittance and electronic-records security. One area of continued focus is overall patient well-being—in short, how to improve the health of anyone inside a hospital, apart from the obvious medical inter ventions that bring patients there in the first place. The health of patients—and staff— hinges on issues as diverse as building layout (ease of access between areas), surface colors (yes, beige rules, except in children’s wards) and even parking. One focus area that is rarely mentioned in sur veys and audits of hospital and healthcare effectiveness is sound. In particular, I refer to the acoustic environments in which patients, visitors and caregivers are enveloped. Over the last few decades, awareness of noise pollution has grown among leaders and decision-makers in many industr y sectors; indeed, even the public media has taken note.

increasingly loud, noise threatens people in many environments, including at home, in offices, and in industrial manufacturing and medical centers alike. According to many scientific studies (see “Suggested References”), widespread noise pollution has been proven to add stressors and increase agitation in children and adults, which, in turn, can lead to worsened health. It should come as no surprise, then, that hospitals are considering ways to improve sound perception in all interior spaces—especially those in which patients are recovering from recent treatments. To be clear, in such cases, we are referring to improving sound and increasing intelligibility within rooms, rather than “soundproofing” or reducing sound transmission between rooms and outside spaces. Soundproofing is best done at the structural level when buildings are designed. To add mass and isolation—the usual soundproofing tools—becomes expensive and disruptive when attempting to improve existing structures. One tried-and-true method to improve sound issues within rooms is to reduce echo and reverberation, other wise known as the over-abundance of sound reflections, perceived as noise and chaotic sound. Echo and reverb are most often reduced by adding sound absorption to flat, hard surface areas in a room or space. Sound absorbers can be used in nearly ever y type of room-improvement situation, from recording studios and performance theaters, to industrial machine shops, to hospitals or laborator y cleanrooms. Moreover, absorption is generally well known and mostly quantifiable. (Sound-absorber products are tested under the ASTM C423 standard.) Most commonly manufactured from fiberglass, as well as other fibrous materials, such as recycled cotton, mineral and wood fibers, sound absorbers are highly effective and relatively economical. The last factor is key for hospital budgets. Although useful, fiber-based absorbers do sometimes have particulate fallout, which can be problematic in food-preparation areas, cleanroom environments, and hospital treatment areas like operating rooms, recover y centers and pharmacies. Fiber-based absorbers also suffer from frequency selectivity, which means that the (continued on page 76)

FUTUREPROOFING EMERGENCY OPERATIONS Riverside CA’s East County EOC was designed for expansion. By Dan Daley

As any security professional will tell you, it’s a never-ending job. You’d certainly hear the same from the professionals who staff the hundreds of state and county emergency operations centers (EOCs) that dot the US. At one, in particular—in Riverside County CA—it’s the EOC itself that’s preparing for its future, laying an infrastructure foundation for future upgrades from day one. The facility, which was originally budgeted at $1 million, but which was later value-engineered to about two-thirds that amount, is a continuing work in progress. As John Bilar, VP of Technology at Spectrum ITC Group, the consultancy that designed and specified the project, said, “[It’s] a marathon, not a sprint.” The project took a former sheriff’s office substation in an existing county building and adapted it as the county’s second EOC, dubbed the East County EOC, located in Indio CA. It’s intended to act either independent of or in concert with the EOC in the city of Riverside CA, which ser ves the west side of the state’s fourth-largest county. (They are connected via WebEOC, a proprietary, web-based crisis-management software that also loops in other local agencies, such as fire and police, for coordinated countywide responses.) The East County EOC’s preparations for future upgrades are reflected most immediately in the room’s videowall, which is composed of a 4x4 grouping of 16 NEC 55-inch displays, although the design specification calls for that wall to have a total of 32 such displays. As part of the initial phase of the project, all 32 displays have been provisioned for in the form of cable infrastructure behind the wall, with the additional displays to be added in a second phase that has yet to be officially scheduled. “The best time to put infrastructure in is at the very beginning, when the walls are already open,” Bilar stated. The East County EOC might have been the second such facility in Riverside County, but it’s not “second city” by any means. Brooke Federico, Senior Public Information Specialist for the County of Riverside Emergency Management Department, which operates both facilities, said that the East County EOC is the first with a videowall. It’s drawn appreciative notice from the journalists who’ve viewed it, as well as from those who’ve used the venue for training and situation monitoring. Of the two facilities, the East County EOC is located closer to the annual Coachella and Stagecoach music festival sites, both of which are in Riverside County. Last year, during the festivals, the East County EOC was activated and worked with local fire, police and EMS in a standby mode. According to Federico, however, the most important thing is the EOC’s ability to take in, manage and display a multitude of critical AV sources flexibly during emergencies. “[This space has] given us the ability to monitor a wealth of sources in a single place, from which we can better manage anything that needs

The East County EOC project took a former sheriff’s office substation in an existing county building and adapted it as the county’s second EOC, located in Indio CA and intended to act either independently of, or in concert with, the EOC in the city of Riverside CA that serves the west side of the county.

tiple facets, beginning even before the first run of copper was put into place. (In fact, budgetar y constraints compelled the use of copper throughout, rather than using the Dante network format.) Bilar recalled having to battle with the local satellite and cable providers about something that residential customers surely understand—unbundling unwanted channels. “The first thing they asked us was, ‘How many television sets do you have?,’ as if this was someone’s living room they were putting cable into,” Bilar recalled. “It was hard to get them to understand that we needed a drop with a ver y specific bunch of [news and information] channels, including broadcast channels.” This had to take the form of what’s known as a ClearQAM—a modulation scheme that allows the RF transmission of digital TV channels in the clear (i.e., unencr ypted and unbundled from other cable or satellite channels). Those channels would provide backup for the OTA iterations of the same channels, which had to rely on external antennas—hardware that is vulnerable to lightning strikes in Indio’s desert location. “We actually had to go to the local franchise authority to make that happen,” Bilar continued. And Martin recalled Dish Network being particularly obtuse on the matter, with the satellite ser vice’s technicians and sales personnel unable to see past residential-type customer needs. “They asked, ‘Where’s the television?’ and we said, ‘It’s in the rack, and there’s 32 of them,’” he sighed. “It was a learning experience.”

immediate attention,” Federico affirmed. “The videowall is great, and we’re ver y happy with how the entire facility operates. Whenever we’ve needed it, it’s been ready.”

‘A Blank Shell’ The wiring and infrastructure stage was also when the AV integrator on the project, ENKO Systems, based in San Bernardino CA, was brought in. The team found the space to be “a blank shell,” according to Greg Martin, AV Systems Engineer/Pro36 Sound & Communications February 2019

grammer on the project. That’s something that many integrators would usually welcome. However, as budget reductions compelled value-engineering-based revisions, the integrator had to find clever ways to accomplish a great deal, while spending less. “The first challenge was how we would be able to build a wall that took in many different sources—from cable, to satellite, to over-the-air (OTA) video, as well as AM and FM radio and streaming—and let them all be viewed and controlled easily,” Martin recalled. It was a hurdle with mul-

Video sources also play a large part in the programming of the EOC’s control system, which is centered on Crestron’s DigitalMedia (DM) platform. Martin said the challenge here was organizing the multitudes of inputs, and the variety of formats they come in on, in a way that would be intuitive to the EOC’s users. Given the nature of emergency facilities that might be unused for months at a time, users might not have training on—or even a passing familiarity with—the systems. However, in the event of an emergency, they will have to get up to speed on them in possibly a matter of minutes. (The facility was activated as recently as this past November, when a voluntar y flood evacuation was is-

ENKO Systems’ certified programmer programmed the EOC control desk’s large touchscreen using the logo icons for individual cable and broadcast networks. Those news broadcasts supply the EOC with much of its operational information.

sued for San Jacinto Mountains communities in the area of last year’s Cranston fire.) Martin, working in tandem with his colleague, certified Crestron programmer Robert Conrad, programmed the control desk’s large Crestron touchscreen to use the logo icons for individual cable and broadcast networks, whose news broadcasts would supply the EOC with much of its operational information. If a user wants to see what ABC is reporting on a particular matter, he or she simply touches that particular button—with the network’s logo on the screen—after being granted permission by a facility manager. That same control screen allows the facility manager, seated at a separate desk in the rear of the room, to configure individual screens in a picture-in-picture format, mimicking how the main wall’s array of 16 screens can be configured. Those options include a single 4x4-unit videowall display, four 2x2-unit displays and a 3x3-unit display, with the remaining screens available as supports around it. Those options can be effectuated by the user simply by selecting a screen format on the master controller. Users can also choose from which video source to view a chosen input. For instance, if the ABC network feed from the broadcast input fails, then the user can instantly switch to that same network through the satellite feed. “They never know when this room is going to be used or who is going to use it,” Martin declared, “so the programming is designed so that you don’t need a CTS credential to operate it.” All that content will come up on the screens in one of the six “pods” of eight seats, which are arranged around rectangular desks in the middle of the room. Each seat faces an NEC 42-inch monitor on a Chief swivel mount, connected to the five main control racks through a Crestron DM receiver. Each pod has one of those monitors assigned as the master screen for that table. In addition, each seat in the pods has an Extron audio matrix switcher, which enables the user to choose an audio source that can be listened to through a pair of beyerdynamic DT 102 headphones. In addition, JBL Control 26CT ceiling speakers, which are powered by QSC two- and four-channel amplifiers, provide sound for the entire room. Both audio and video can be accessed using a similar

touchpanel controller, or other device, in any of four satellite rooms (adjacent to the main EOC) that are used for utility applications, such as huddle spaces or meeting rooms. That content comes in through coaxial cable. (The cabling in the pod area took long enough that Martin, who worked on it during a Community Emergency Response Team (CERT) training session, which was held in the EOC early on, actually became CERT-certified himself!)

Wire Management Much of what enables all the functionality described is below ever yone’s feet, under a paneled floor and atop a slab that had been saw-cut and lowered, creating an 18-inch-deep space for cabling. And there was plenty of it, according to Martin, who estimated the project team installed more than 100,000 feet of wire for audio, video and control applications. However, because copper constituted the bulk of the wire type, care had to be taken in placing which cables where. For instance, RF-shielded coaxial cable was placed in a 16-to18-inch-wide wire basket on the far side of the under-floor space, with video cabling on the other side of the basket, as far apart as possible; that was to reduce the potential for interference. The analog audio wires were run up the middle of the baskets, and, anywhere they crossed, the wires were bent at right angles to minimize crosstalk. All the wire baskets were laid atop grounding strips, and the entire control and rack were enclosed in a halo ground system, connected at each corner of the room to an external earth-ground electrode via a separate grounding bus bar installed by an electrical subcontractor. “The EOC is out in the middle of the desert, where the air is very dry, (main story continued on page 69)

Audio Arts Mass Transit

42 Sound & Communications February 2019

By Jim Stokes The newly renovated Downtown Berkeley BART (Bay Area Rapid Transit) Plaza created an enjoyable get-together environment for local residents, the folks who work downtown and visitors to the famed city of Berkeley CA. Accordingly, in this article, we will explore the public-art, sound and lighting facets of the plaza, while also examining the BART station located directly below the gathering place. The $9 million renovation opened on October 18, 2018. The update included a newly paved main entrance, speaker and light poles, stage lighting, and trees and landscaping for the plaza, which is the heart of downtown and a transit portal for the city. Furthermore, the plaza is a place to showcase the creative and artistic soul of Berkeley. The activation plan was developed by the Downtown Berkeley Association (DBA), working in close association with city of Berkeley staffers and the Civic Arts Commission (CAC), and in consultation with Mayor Jesse Arreguín and Council Member Kate Harrison.

The other use for the sound system is for live events and performances in the designated stage area, whereupon the A/V Binloop is turned off and performers can use live sound equipment. “The system in set up to be flexible,” Lovvorn pointed out. “It has many uses to help facilitate activation of the space. The performances don’t happen all the time; there may be two a week, and that would be in the evening or at lunchtime. The balance of the time, the sound installation with the A/V Binloop is playing.”

shadows of the maps onto the surrounding plaza. Whether seen by day or at night, the artwork evokes the interconnectedness of all people and places around the world. Complementing the global display, the first sound-art installation in the plaza was “Flow in Place” by another Berkeley-based creator: composer Chris Brown. The work is composed of field recordings of musical performances, along with natural and urban environments from around the world. (For additional details, see the sidebar titled “Sound-Art Installations.”) The plaza design went from a classic aesthetic to a modern glass canopy. The icositegragonal—or 24-sided—rotunda that rose above the Downtown Berkeley BART station since 1973 has now given way to a more open-designed plaza. Gone are the old red bricks that once surrounded the station entrance and the scattered benches. “The idea was, when the plaza reopened, to have it feel like a totally different space,” Jennifer Lovvorn, Chief Cultural Affairs Officer, Civic Arts Program, for the city of Berkeley, revealed. “We wanted it to feel like a totally different space from the previous big brick architectural features. There were some permanently built-in benches that really divided up the space and that made it not feel warm and welcoming. There were some illicit activities taking place in little nooks and crannies that people could duck into. So, we wanted the new space to be welcoming and available for use by ever yone.” “One of the really important things about this location is that the Downtown Berkeley BART station, which is right below the plaza, is the gateway for a lot of people coming to our city,” Lovvorn continued. “The university is one of the huge draws for people coming in. A lot of people arrive by BART public transit, and buses also stop at BART.” Lovvorn explained that the primar y purpose of the integrated AV elements is to create a sound environment. That includes the Alcorn McBride A/V Binloop playing continuously within the limits of the city’s sound ordinance, which is 7am to 7pm from Monday through Friday (and extended to 8pm on weekends). 44 Sound & Communications February 2019

Integration Challenges BugID, based in San Francisco CA, facilitated the audio being heard throughout the plaza, which includes prerecorded content, public address, live performances and artist soundscapes. The integrator’s President, Matt Lavine, was the lead designer for the plaza space. Other key personnel included the project’s lead installer, Davis Selland, and its AV systems programmer, Isaac Darnell. The AV design/install company’s contract was $295,000 for all the AV and lighting equipment, as well as for installation services. (Note: That figure does not include content-related costs.) “I was brought into the project in December 2015,” Lavine recalled. “So, I was helping out the city and the Civic Arts Commission figure out ideas, designs and the budget for almost two years. The city of Berkeley hired BugID in November 2017, and we finally went live in October 2018.” Continuing the stor y, Lavine said, “It was definitely a challenging project to create a soundscape that’s easy for artists and the city of Berkeley to use. Another challenge was installing a high-end professional sound system on a city street. That’s not a typical situation. There are security measures you wouldn’t normally take.” That aspect of the project was considered by BART a few years prior to the integrator coming onboard. “By the time this came to us in 2015,” Lavine resumed, “BART already had drawings and space allocations for where the electrical equipment would go. But nobody thought about audiovisual equipment in a public-works space—especially in a street plaza.” In short, this project—with its AV equipment and the low voltages that come with it—was anything but typical. “It was definitely

a challenge to work within the constraints of BART and the city of Berkeley in terms of tr ying to fit an AV rack on a street inside a tamper-proof box,” Lavine elaborated. “And then there was the issue of ventilation, because there’s no HVAC…no air conditioning. Most of the telephone and electrical equipment on the side of the street consisted of transformers, relays and related equipment.” Lavine explained that BugID’s solution was to design a rack that would fit inside an industrial-grade metal cabinet. At the same time, the integrator worked with mechanical engineers to help design a fan and exhaust system to make sure sufficient heat was removed from the cabinet.

Details On Plaza Install Let’s zoom out to take a wide view of the BugID install. As noted earlier, prerecorded audio content on the plaza is played back on eight discrete audio channels via an Alcorn McBride A/V Binloop player. An Alcorn McBride VCore-S show controller was included in the system to enable scheduling of content playback. The audio content is delivered via eight Meyer Sound UPJ-1XP compact VariO speakers, which are powered by a dedicated external DC power supply. It was a natural move for the city of Berkeley to turn to Meyer Sound for the speakers, Lavine added, given that the venerable sound company is itself based in Berkeley. There were a number of considerations taken with regard to speakers, including their security. “We put security chains and bolts on all the speakers,” Lavine recalled. “They’re mounted up 14 feet [of the 21-foot poles], so you have to be pretty crafty to get a speaker off a light pole!” Continuing, he turned to power. “One of the advantages of the UPJ-1XP is that it’s a 48V speaker system,” Lavine said. “With one MPS-488HPp power supply, we’re able to power eight speakers. So, the Meyer Sound speakers were the perfect solution for this application, and they sound great.”

Audio Playback Another consideration was playback. “We didn’t know when we were brought in that there was no one from the city who could operate this system,” Lavine pointed out. “So, we really had to think about how various artists coming in would use the system. We thought about a number of things, such as putting in a computer. But computers take a lot more maintenance over time, and you continually have software updates.” “We went with Alcorn McBride, which makes professional-grade units that run 24 hours a day,” Lavine affirmed. “The A/V Binloop plays eight channels of discrete audio, and we can schedule it. For example, Monday through Friday, between 11am and 4pm, we might want to play an artist soundscape. Then, we might want to play different music in the evening.” Elaborating, Lavine noted that, between the Alcorn McBride VCore-S show controller and a Crestron CP3N 3-Series central 46 Sound & Communications February 2019

controller, BugID can create schedules of content and then load CompactFlash (CF) cards into the A/V Binloop for the various soundscapes.

Live Presentations The city wanted to be sure that, for bands and other live performers, a small mixing board could be jacked into the system and used with the permanently installed Meyer Sound speakers. Alternately, the city might seek to use the sound system for a speech or similar live presentation. “Since it’s a public space for performance art, someone may want to read poetry,” Lavine explained. “External microphones can be plugged into the system. That’s where the Crestron TST-902 wireless controller with an 8.7-inch screen comes in. You can take it out of the rack and walk about the plaza with it to adjust sound levels.” There are two different DSPs to move and process the audio. Meyer Sound’s Galileo Galaxy 816 is the speaker’s final EQ. There’s also a QSC Q-SYS Core 110f for matrix routing and control. “We’re able to call up various presets and adjust levels on the Crestron,” Lavine explained. “Then, the QSC feeds the Meyer Galileo Galaxy. We wanted to create a mixer on the Crestron touchpanel that was easy to use. So, our touchscreen has control whether someone is using it as a PA or doing a soundscape on the plaza.” A Dell Latitude 5480 14-inch laptop is provided for artists who want to become more creative with sound; it offers them access to the QSC and Meyer Sound DSPs.

A Flexible System Lavine elaborated on some other flexible features of the plaza system. In creating a soundscape, the artist might want to create a stereo piece using the eight speakers. That can be replicated as left/right stereo, or it can be done as eight discrete channels. “There are individual presets that are on the touchscreen that are really unique in recalling the artist’s feed use,” he said. Furthermore, the user is not wedded to the 8.7-inch wireless touchscreens. “When I designed this system, I didn’t want a wire-

less-only solution because there are some drawbacks,” Lavine commented. “First, people forget to put them on the charging dock. Second, people walk off with them. Third, they drop them.” He continued, “So, we attached a Crestron TSW-560-B-S five-inch touchscreen to the AV rack as a default. That way, we know there’s always a fixed screen controller available.” There are two of the larger TST-902s: one mounted and the other freer to enable people to roam the plaza. In general, “turnkey” was an operative guiding principle for BugID. “It’s a full turnkey system, because we didn’t want a system where the user would be relying on an AV integrator to make all the changes,” Lavine said. Staying with that thread, BugID provided four Shure SM58CN cardioid dynamic vocal microphones. “[Presenters can] plug in a microphone

Sound-Art Installations The first sound-art installation on the Downtown Berkeley BART Plaza was an original, site-specific composition, called “Flow in Place,” by local composer and electronic musician Chris Brown. The work, which ran for two months, was composed of field recordings of musical performances augmented with natural and urban environments from around the world. The recordings were shuffled together into sequences that accompany the movement of people heading from the BART station entrance through the plaza, suggesting conversations and connections between distant places and global environments. (For more information, visit Brown’s installation was the first in a series of 10 sound-art installations, with presentations subject to change. The slate of composers included in the series includes a mix of preeminent sound artists as well as exciting newcomers to the scene. “Berkeley and the East Bay are home to a thriving electronic arts scene, and the new Downtown Berkeley BART Plaza has been built with a sound system infrastructure to give the city of Berkeley a unique opportunity to present this exciting art form,” Berkeley Civic Arts Commission Chair Kim Anno stated. “This one-of-a-kind audio environment will engage the public in inspiring and provocative ways.”

and use the speakers as a PA,” Lavine pointed out. “On the plaza’s opening day, the user brought in a sound mixer to plug into the system. The DBA was able to manage that by bringing in the artists and dealing with rentals. Meanwhile, we’ve been training people from the DBA.”

Lighting Considerations BugID worked with two Berkeley-based lighting consultants to design lights on the plaza poles. They were Alice Prussin, of Illuminosa Lighting Design, and theatri-

cal lighting designer Jack Carpenter. “We wound up modifying the existing light poles and putting in two ETC Desire D60XTI 60LED wash lights on every pole, except two light poles closer to where the stage would be set up,” Lavine said. “That location has three lights.” All of them are color-changing lights, rather than robotic, because the budget wasn’t available for robotic lights. “Plus,” Lavine added, “we had to think about long-term maintenance.” There’s an ETC CS20 20-fader DMX lighting console that plugs into the wall panel

that also accommodates microphones. The DMX has presets of various lighting colors and changes. For convenience, multiple presets are on the Crestron controller, so the user can run things right from the touchscreen. Indeed, it’s possible to do a whole audio and lighting show for which the PA volume and all the stage lights are controlled from the Crestron. Summing up, Lavine said, “It was great for me to see the city embracing public arts…to be part of a project that’s encouraging artists of the community to express themselves and be creative. It’s in an environment that’s enjoyable to walk through, sit in, have lunch in, or hear a rally or hear a live band.” He continued, “It’s rare to be part of a public-works project that is creating an immersive soundscape. It was challenging, but, to hear Chris Brown as the first artist at the opening, it was definitely worth the amount of time and effort put in.”

Austin-Bergstrom International Airport undergoes extensive upgrades.

By Suzie Hammond Austin TX fancies itself “The Live Music Capital of the World,” which is splashed up in lights in several places in Austin-Bergstrom International Airport and on signs across the rest of the city. The other slogan embraced by the Austinites is “Keep Austin Weird.” Many small businesses in the surrounding area do their best to be more interesting than your usual retailer is. Vegan taco wagons, clothing-optional hippies, and a variety of music and art festivals intersect here, creating a culture that is truly vibrant…and distinctively Austin. As a public utility, Austin-Bergstrom International Airport was involved in discussions about its expansion starting before 2012. The plans went through a number of committees and elections in Austin before finally getting to the point at which portions could go out for various contractors to bid. (Naturally, the process of collecting and reviewing bids was rather lengthy. In addition, any changes related to newer specifications of just-released equipment had to be reviewed thoroughly.) After the typically intensive process for public works, project design and architecture was awarded to Gensler. The design giant, which is headquartered in San Francisco CA, comfortably made more than $1 billion in revenue each year for the last five, and the company operates offices in 46 cities in 16 countries. According to its website, “Gensler is a global design firm that partners with clients to create more livable cities, smarter workplaces and more engaging leisure destinations.” Sounds like a match for Austin’s ethos! 50 Sound & Communications February 2019

A Wide View There’s plenty of audiovisual technology to discuss across the Austin-Bergstrom International Airport campus. But, before we delve into digital signs, paging systems and so forth, let’s take a wider view of the overall master plan, including its non-AV-centered elements. Robert Mercado, Project Manager and Architect with the city of Austin Department of Aviation, is helping to oversee this major undertaking, which, although well on its way, has not been entirely completed. He explained that the plan, which includes adding nine new gates, would accommodate a projected 15 million travelers annually—a 36-percent increase over the airport’s existing capacity. In addition to the new gates, the project entails a 70,000-square-foot extension that contains 19,000 square feet of retail space, an outbound baggage area, various airline offices and additional passenger amenities. Project planners also envision a large, outdoor obser vation deck, pet-centric spaces, a variety of improvements on existing structures and upgrades across the terminal to enhance the passenger experience. The vision outlined is beyond reproach, but one of the challenges in achieving it has been the fact that the airport has had to remain fully operational throughout. (More on that shortly.) Apart from the obvious, what else is expected from an airport renovation and expansion these days? Befitting its city culture, Austin-Bergstrom includes elements such as music-performance areas and artistic spaces. New termi-

nal items also include a variety of informational screens that inform travelers about, for example, which are the quickest security lines to get through, improving the passenger experience by cutting wait times. There are also information screens to inform inbound travelers about wait times for customs and baggage claim, as well as other vital information. Clearly, this story is now transitioning to the AV “sweet spot.” To keep things digestible, we’ll focus on three different AV-related aspects of the overall project, taking each in turn.

PA System Julien Peterson PMP, CTS-I, Project Manager with Ford AV, a widely known AV integrator with headquarters in Oklahoma City OK, took the lead with respect to installing the airport’s new PA system, which is centered on a mix of AtlasIED speakers and amps, JBL speakers and QSC surface-mount speakers. “Everything having to do with the PA system was taken out and replaced with digital equipment,” Peterson affirmed. “Overall, there were about 1,000 new speakers put up, and all the microphones were replaced with much

better equipment.” He continued, “Fortunately, we could use some of the past conduiting that was in the existing parts of the airport, but, naturally, the new installs for the nine new gates needed entirely new gear.” Let’s turn first to the speaker side. From AtlasIED, Ford AV specified 547 FA138T167 eight-inch coaxial speakers with 16W 70.7V transformers, as well as 20 FAP82T eightinch coaxial in-ceiling speakers with 60W 70/100V transformers and ported enclosures. From JBL, the complement included the following: 137 AC16 ultra-compact, two-way loudspeakers with 6.5-inch LF transducers; 84 CSS-1S/T compact, two-way 100V/70V/8-ohm loudspeakers; 13 Control 29AV-1 premium indoor/outdoor monitor loudspeakers; and nine Control 24CT background/foreground ceiling loudspeakers. Additional speakers from QSC included a whopping 634 AD-S4T surface-mount models. AtlasIED power amplifier cards include 95 IEDT6302L class D, dual-channel, 600W, 70V; 20 IEDT6152L class D, dual-channel, 300W, 70V; and 18 IEDT6602L class D, dual-channel, 1,200W, 70V. On the microphone side, the AtlasIED complement is as follows: 44 IEDA528HDT-H 528 Series digital communication stations; 34 IEDA528SK-H Sidekick four-button expansion

stations; 14 IEDA528HDT-G Ethernet microphone stations; and an IEDA528SRMEH Ethernet microphone station. As intimated earlier, Peterson affirmed that the biggest challenge for this aspect of the project was definitely the continuous high-traffic situation of a busy airport—particularly when dealing with scissor lifts, heavy equipment and mounting components. And that’s despite the fact that work hours were scheduled for when air and foot traffic were at their lowest levels. “Sometimes, we would need to wait to complete a section by returning later in the evening, when traffic would be less of an obstacle,” he explained. 52 Sound & Communications February 2019

Peterson continued, saying, “We used a scissor lift, which needed a plywood base under it for ever y move. Additionally, a canvas cover was necessar y to protect the floor surfaces.” And, for some aspects of the job, the Ford AV team had to put out event notices weeks in advance, so ever yone else inside and outside the terminal could plan accordingly. In light of the extensiveness of the project—as mentioned, more than 1,000 new speakers were installed—executing the design was no simple task. As always, though, Ford AV was up to the job, having integrated countless “A”-class projects over the decades. According to Peterson, “I had a well-trained and thorough crew, so we could do equipment moves and overhead installs as rapidly as safety allowed. Our speed and efficiency meant we could get 54 Sound & Communications February 2019

done in good time.” He elaborated in much greater detail, saying, “It took our crew of three to five people about a year to complete this job. It wasn’t difficult to do the actual AV work, as that was fairly straightfor ward. The complexity came from the size of it all. Each part needed to be checked out thoroughly before moving for ward.” He added, “And, I had to make sure we were in compliance with Occupational Safety and Health Administration (OSHA) regulations. For instance, when we drilled into the cement for the outside installs, we needed the silica attachments on the drills for our workers not to be inhaling that cement dust and that sort of thing.” He noted, “I know some contractors are not too particular about things like that, but we want to take care of our workers.”

Another interesting part of the broader project at Austin-Bergstrom centered on six double-sided LED walls—totaling 12, all together—that were placed outside, curbside. The first order of business was to get special plans drawn up for the metal superstructure that holds the signs, which have to be able to withstand winds of up to 120mph. Austin Commercial, one of the largest, most diversified builders in the US, produced the frameworks. When the overarching structure was put up, the AV implementation could begin. Mayo DeLeon, Business Development Manager, Visual Innovations, shared details about the hardware installation. The 12 LED walls are composed of 72 Delta Products SX-6MF outdoor, 6mm, 768x768mm (WxH), front-ser viceable LED tiles. Each LED wall is composed of six panels and weighs just less than 400lb. Each wall, in total, is approximately 7'6"Wx5'H. The LEDs rotate through information and require periodic updating. The screens’ purpose is to alert travelers where each airline is located and to inform motorists where standing and drop offs are permitted. The installation process required the use of a small forklift for the actual lifting and installing. The Delta panels were fit together with the help of Gene McCutchen,

Project Manager with Br yComm, as well as Benjamin Stewart, Electrical Engineer with Delta Products. With the previous experience the team had, the install went extremely smoothly. The Delta panels fit into the newly made steel enclosures, and were daisy-chained to achieve seamless messaging. DeLeon from Visual Innovations worked with Shaun Davis, the IT Department Systems Architect with the city of Austin, to manage the software side. Part of Visual Innovations’ scope was to install the Scala digital signage software on the client-provided server and media players and to provide software integration to allow the client data to be programmed into the displays, while also assisting in the initial setup and scheduling of the playtime. Visual Innovations also provided Scala certified training and custom script software integration. Davis related that, just as the team had completed the hardware installations and software integration, a new airline was commencing ser vice through AustinBergstrom. Davis pressed for a trial the night before the newly arriving airline went

“live.” The LED walls and software were put through their paces and ever ything worked perfectly. The next morning, the entire system, complete with the new airline, went into operation seamlessly. The entire crew was delighted! Incidentally, within a few weeks, a major weather event brought winds exceeding 100mph. As predicted, the LED walls that Visual Innovations brought to life withstood the high wind velocities and slashing rain.

As part of the Ignite internship program, interns spend time with employees to learn the ins and outs of specific roles.


Resources exist to seed the next generation of integration professionals. By Kelly Perkins For as long as I’ve been in the systems integration industr y, it’s been a challenge to tr y to explain our work to non-industry professionals. Over the years, the industry has changed not only to include AV, but also to include low-voltage communications, life safety and security, nurse call and IT/network technologies. Earlier this year, a friend and former colleague of mine, Justin Watts, started a conversation among a group of about 100 integration professionals on Facebook. He said, “I’m often asked what, specifically, I do for a living. I have a diverse career path that spans multiple segments of the IT/AV universe, so it’s sometimes hard to connect all the dots. How do we explain what we do to people outside our industr y?” Responses to his post ran the gamut. Ever ything from “I work in audio—no homes or cars. No, I can’t fix your home theater system,” to “I tell people that I automate big buildings and other fancy places.” The most concise response, at least in my opinion, was, “I simply say, ‘I help people communicate through the use of audiovisual technology.’” This might be an obvious statement, but, if it’s confusing to you and me, just imagine how confusing it is to those we’re tr ying to recruit! This is just one of many challenges that we face in bringing new talent into our industr y. I’ve been the NSCA Education Foundation Director for about six months now, and we hear the same number-one business concern discussed over and over: “We need skilled technicians. We need design engineers, programmers and project managers.” And on and on. It doesn’t matter if you’re a CEO, an HR director or a manager of technical ser vices; the shortage of skilled workers is affecting everyone. The average NSCA member has at least seven open positions at any given time (nationally, that equals out to 17,000 open positions). Current industry training programs, such as Electronics Systems Professional Alliance (ESPA), fill only 600 56 Sound & Communications February 2019

(3.5 percent) of those positions each year. Yikes. So, here’s the million-dollar question: How the heck do we fix this? No one has a silver bullet, but there are things we can do to attract, recruit and retain skilled, knowledgeable employees. The NSCA Education Foundation is spearheading efforts to help integrators and manufacturers fill these gaps, but there are also things you can do on your end. Based on feedback from integrators, manufacturers, consultants, independent reps and even end users, I’ve compiled some ways you can contribute. Align Our Conversations: Let’s start by agreeing on a name. Are we “AV”? Are we “IT”? Are we “low-voltage electronic systems contractors”? How about “communications technologies”? Within our own industr y, we all refer to what we do differently. A good (and basic) first step would be to establish a consensus about how, exactly, we’re going to refer to ourselves. Spread The Word About Opportunities: Without question, our industr y is one of the best-kept secrets in today’s job market. Post-secondar y students interested in technology have no idea how optimistic their career prospects in our field might be. They don’t know how hungr y we are for talent. They don’t know how what we do lays the foundation for almost ever y organization’s communication, productivity, efficiency and safety. And most, as we know, don’t know that our industr y even exists! Whenever we have the opportunity, we have to get the word out about what we do and about the career paths available in our industry. To do this, we have to educate ourselves—that means learning how to talk about our industr y and the paths we offer to high-paying careers.

To connect students, young professionals and schools to the industry, Conference Technologies Inc. hosted interns this past summer as part of the Ignite internship program.

The Ignite Initiative The NSCA Education Foundation’s Ignite program exists for a single purpose: that is, to connect students, young professionals and schools to our industr y. Ignite was first unveiled at NSCA’s Business & Leadership Conference (BLC) in 2016, and we’ve come a long way since its inception. The Ignite program’s sole focus is to showcase the industr y and its career opportunities to jobseekers, students and educational institutions. Ignite provides marketing materials to high schools/technical colleges and Ignite Ambassadors (90-plus people who have agreed to support Ignite), and it provides materials to industr y professionals who want to speak locally about career opportunities in our industr y. Ignite also hosts an industr y-specific job board. Last year, the Ignite pilot internship program launched, having 12 participating organizations and 25 interns. The internship process works as follows: Phase 1: Onboarding: During this time, interns gain an understanding of your business, spending at least one day in each department to understand its inner workings and how each department affects the others. Phase 2: Ride & Decide: For a five-week period, interns will gain specific skills and knowledge to spark interest in our industr y. Phase 3: Learn & Earn: Using NSCA’s Certificate as a Systems Integration Professional (C-SIP) program, interns gain relevant experience and credentials in sales, (continued on page 78)

Toward the end of their internship experience, students craft essays that document what they’ve learned with regard to quality, performance, process improvement and personal growth.

Students participating in the Ignite internship program spent the summer getting hands-on experience in all departments of participating integrators and/or manufacturers. February 2019

Airports Getting In The Loop Hearing loops are the wheelchair ramp of the hard of hearing. 58 Sound & Communications February 2019

Photo courtesy Greater Rochester International Airport.

An information counter at the Greater Rochester International Airport.

By Stephen O. Frazier Fear fills the hearts and minds of many hardof-hearing travelers as they disembark at the arrivals area of most American airports. They’re filled with the fear of being aurally blind. With rushed, garbled announcements in the concourse area and at the gates in most airports, travelers often don’t know whether they’re coming or going. Gate-change announcements are incomprehensible, flight delays are lost in transmission and pages over the PA system are simply indecipherable sounds.

Welcome Change Happily, however, that situation is changing in a growing number of American airports. Leading that change is the Greater Rochester International Airport, in Monroe County NY, which has

become the poster child in the movement for improved communication access for hard-of-hearing air travelers. The airport administration, in line with the Hearing Loss Association of America (HLAA)’s admonition to “Get in the Hearing Loop,” has devoted a good portion of a $40 million grant from the state of New York to the installation of hearing loops and other technology throughout the terminals. Hearing loops, which are known in the AV world as audio frequency induction loop systems (AFILS) are, in their simplest form, a discretely installed wire that circles an assembly area that’s connected through its own amplifier to an electronic sound source, such as a PA system. The loop broadcasts the sound from that system as a silent electromagnetic signal to the telecoils in hearing aids and cochlear implants (CIs) of anyone inside that loop. What are telecoils, you ask? They’re tiny wire coils available in most hearing aids and all new CIs. They receive the loop’s silent signal, and the hearing devices turn it back into sound. Installation of AFILS technology has surged in the US in the last decade, turning up in locations as diverse as New York NY taxicabs and the US Supreme Court; now, it’s in a growing number of airports. In the case of the Greater Rochester International Airport, the loop wire—all 19,000 feet of it—was buried in the scored concrete floors of the terminal and connected to 23 separate Contacta HLD9 modular phased array loop drivers, each with 10A RMS of compliance current at 1kHz sine wave to overcome the abundance of steel in the floors. These 400W drivers serve all the departure gates and two separate concourses. The installation was performed by the Hearing Loop Systems Division of Parkway Electric & Communications, of Holland MI.

Starting From Check In With the completion of that project, access to hearing loops now begins with check in, at which time ticket agents use counter loops to communicate with passengers, and ends as a traveler boards the plane. In addition to the loops installed in the floors, more than four dozen counter loops are spread throughout the terminal. What’s more, the use of telecoil/loop technology to ser ve passengers continues as they move through the security area after having checked in.

Passengers proceed to looped concourses and departure gates that feature phased array loops, which contain sound to each individual gate area. Attendants at those gates also have a counter loop at their desk, enabling them to communicate privately with individual travelers. What’s more, counter loops are featured at car-rental desks, gift shops, food-ser vice cashier stations and other points of ser vice. As excellent as all of that is, here’s the limitation: Not even nearly four miles of loop wire, plus an abundant supply of counter loops throughout the terminal, can help a traveler if he or she doesn’t have telecoils. So, tablet computers that feature an Interpretype software program are on hand at all points of ser vice to communicate by voice-to-text, or even sign-language-to-voice. Meanwhile, overhead, color-coded TV monitors visually relay information being broadcast over the loops. The Monroe County Executive, Cheryl Dinolfo, told the local TV station, “Our goal is to create a safer and improved passenger experience with state-of-the-art facilities and amenities.” With nearly 2.5 million travelers passing through Rochester’s terminals each year, up to an estimated 500,000 could have a measurable hearing loss; and, for those in that half-million who have telecoil-equipped hearing aids or CIs, none will have to wonder what an announcement was, if their gate has changed, if their flight is delayed or canceled, or if they’re being paged. Some travelers, seeking to rid themselves of the auditory overload present in the terminal, might even choose to turn off the mics in their hearing aids and rely solely on their telecoils to provide the information they need to get to their gate and board their flight.

One Of Several Rochester is just one of several airports to follow the example set nearly a decade ago, when the Gerald R. Ford International Airport in Grand Rapids MI became the first in the US to install this kind of technology, placing it at all its gates and in the grand concourse.

Tara Hernandez, the airport’s Marketing Director, reported, “The response to the loops by hard-of-hearing travelers has been tremendous, because it takes the stress out of travel.” The Kalamazoo/Battle Creek International Airport soon emulated Grand Rapids; then, terminals in Muskegon MI and South Bend IN followed. As time passed, loops were installed at some Delta Air Lines gates in the Detroit Metropolitan Wayne County Airport as well as in the Minneapolis-St. Paul International Airport, in which the international arrivals area and an “Art at the Airport” rest and waiting area were looped. Also adopting hearing-loop technology in various ways were the Fort Wayne International Airport and the Santa Barbara Airport. Phoenix Sky Harbor International Airport, located in Maricopa County AZ, is a major hub for Southwest Airlines and several other air carriers. It has joined the move to provide better communication access as part of a modernization project that began at its Terminal 3. Sky Harbor’s Senior Technology Systems Project Manager, Craig Fuller, reported that the airport has installed inductive hearing loops at 15 gates on the South Concourse, and it plans to loop an additional 10 gates on the North 60 Sound & Communications February 2019

Concourse next year. To avoid even the possibility that cutting channels in the cement floors of the terminal for loop wire would weaken them, the airport required that the 14,000 feet of loop be copper tape installed on the floor surface, instead of in scored channels in the cement floors. The installation uses Contacta’s HLD9 amplifier driving a phased array patterned loop, which confines each gate’s loop signal within its borders, and which avoids the signal overspill one might encounter when using a typical perimeter loop. And the list goes on! In Austin TX, Hearing Loop Systems has looped 12 gates at Austin-Bergstrom International Airpor t. In Memphis TN, a major modernization program is in the planning stages at Memphis International Airpor t; it will include induction loop systems in the concourse and in all gate/ hold room areas. Atlanta GA’s Hartsfield-Jackson International Airport was recently honored by the Federal Aviation Administration (FAA) for its efforts to enhance accessibility for passengers and guests who have disabilities. Balram Bheodari, Interim Airpor t General Manager, said the airport placed teletypewriter (TTY) devices, which provide voice-to-text communication for the deaf or severely hard

of hearing, at strategic spots throughout the terminal, while also installing hearing loops at information desks “to ensure a best-in-class experience is accessible to all of our guests.” It seems clear that the looping movement is gaining momentum. With the wind at their backs, advocates are pressing for the airports in Albuquerque NM, Salt Lake City UT, Seattle WA and other cities to get in the loop.

Around The World American airports have been slow to address the special communication needs of hard-of-hearing travelers. Hearing loop technology is common in the air terminals of many major cities around the globe, from the East to the West. In Russia, all three of Moscow’s airports feature hearing loops. Domodedovo Moscow Airport, for example, installed loops in nine zones of the terminal, which are connected to the airport’s system of automatic announcements. In Seoul, South Korea, Incheon International Airport recently installed hearing loops at information desks so that hard-of-hearing travelers can more easily communicate with attendants. Airports and train terminals in the UK have featured hearing loops for years. Gatwick Airport in West Sussex, England, is

Summing Up The discussion above references just a few examples of the multitude of airport terminals around the world served by hearing loops. That testifies to a belief among many that, for those with hearing loss, loops are a preferred and effective way to serve their communication needs in large places of assembly. Importantly, telecoil-equipped hearing aids or cochlear implants that are acquired in the US—or anyplace else in the world, for that matter—will work with the hearing loops in any venue a traveler might visit: from the

filled with signs that show what they call the “sympathetic ear” symbol. It’s visible from check-in counters to gates; plus, a new waiting area, which opened last summer, is specifically designed for those who have disabilities. Like Gatwick, Heathrow Airport in London, England, has loops available at various points throughout the terminal. Meanwhile, at Manchester Airport in Greater Manchester, England, check-in counters are looped and phased array systems have been installed in key areas of the building. Crossing the channel to France, Charles de Gaulle Airport near Paris, France, offers travelers waiting areas within each of the airport’s terminals, each of which is equipped with induction loops. Moreover, the customer-assistance terminal is fitted with a loop. In Spain, Madrid-Barajas Adolfo Suárez Airport has installed hearing loops in a variety of locations to improve accessibility for hearing-aid users. The recently adopted inter national symbol for hearing-loss assistance features a “T” if that assistance is pr ovided by hearing-loop/telecoil technology. Here in the US, it is usually blue; however, abroad, it might be a variety of colors. In all cases, though, the symbol tells har d-of-hearing travelers to tur n on their telecoils. As is clear, travelers in an increasing number of cities—both domestic and international—can expect to see them as they traverse airpor ts.

Intrepid Sea, Air & Space Museum in New York, to the tourist information office in the tiny village of Les Eyzies-de-Tayac-Sireuil, France. Hearing loop signals are the same frequency everywhere, and, assuming they are installed correctly, they all meet the universal standard for signal strength and uniformity contained in IEC 60118-4. Hearing loops are the wheelchair ramp of hard-of-hearing people…an accommodation that will make their disability a little less disabling. And that’s why it’s worth celebrating so many airports now getting in the loop.

Getting Up To Speed For An AVoIP Future, Part 3 The IT manager and you.

62 Sound & Communications February 2019

By Rob Ziv, CTS-D, CTS-I, ISF-C, DSCE Almo Professional AV In the previous installments of this series, we discussed some of the benefits of IP signal distribution, along with a few technical terms to help sift through the noise in the market. However, when network-based solutions utilize the enterprise network infrastructure, they often face the scrutiny of IT managers. As such, it is essential to both understand the IT department’s concerns and prepare yourself to address them accordingly. Although there are multiple potential pain points for IT, they come down to a few closely related technical areas; among them, the top two are security and bandwidth. Before going further, let’s get some perspective. I anticipate that many people who read this have limited experience in AVover-IP (AVoIP) matters. (Other wise, why would you be reading this primer, right?) The potential appeal of this piece is to offer some form of enlightenment—or, perhaps, fear reduction—about the subject. After all, even with the convergence of AVoIP, is it reasonable to expect all AV specialists to know ver y much about IT? I ask that rhetorically, as it illustrates the expectation I have found from some AV professionals who (incorrectly) anticipate that IT people will understand AV. I, too, had the same misperception that IT department heads would already know about AV. Simultaneously, my non-scientific research anecdotally shows that some IT managers assume AV people understand little about networks. As is usually true, reality doesn’t lie in generalizations. It is prudent to put aside assumptions about the person who sits across from you, and, instead, to have an open dialogue from the outset about perceptions and concerns. Sometimes, concerns can be alleviated through dialogue. Be prepared to answer the following question: “What do I need to do to my network to get this to work?” The easiest ways to fail in implementing AVoIP is to choose

an unproven solution or to use the cheapest option. Be prepared to address a whole range of issues with the IT managers. If you are unsure of the answers to the questions I introduce below, talk to the manufacturer’s support team. If the manufacturer is unable to answer your questions, then find another provider! Working with vendors that offer proven solutions, with pre-sale and post-sale support, will help maximize the potential for success. One of the first questions to ask is whether the manufacturer offers firmware and security updates. If so, are those updates automatic? If they are not automatic, how will deployment of the latest patches be ensured? It’s also good to ask how much bandwidth the solution requires. Most network traffic outside of AV is bursty, which means there are usage surges, which are followed by lulls. Imagine you are shopping online. While the vendor webpage loads, network traffic increases. After the site loads, downloading stops while you read the page, only to resume with the next click. In between, the network is free to handle other tasks, such as email or web sur fing by colleagues. By comparison, sending real-time audio and video over the network is constant, and, therefore, it consistently demands higher bandwidth. Speaking of bandwidth, not all network switches are created equal. We typically hear of switches rated by their port speed (for example, 1Gb). However, the por t speed does not mean all ports can pass data at the same time at that rate. The backplane speed is the maximum amount of data that a switch can for ward at one time, regardless of the number of ports in use. When deploying an AVoIP solution, whether on

a dedicated network or riding on the organization’s existing infrastructure, the backplane of switches must support the required data throughput. Additionally, keep in mind that some AVoIP standards (i.e., AVB/TSN) require specially certified switches. Does the IT department have to open ports on the firewall? If so, which ones? Opening ports on a firewall creates work for IT and has the potential to increase

security risks. Some AVoIP solutions sit inside the corporate firewall, others are outside and some go in the DMZ (a network between the internet and enterprise network, intended to provide additional security from outside threats). How is AV traffic data prioritized? For example, does it require configuring quality of service (QoS)? Although many methodologies use DiffSer v for QoS, they do not (continued on page 79)

MARKET BRIEF By Amanda Mullen

Government Facilities And Public Works Major government shutdowns, much like the one that began at the end of last year, quickly demonstrate to Americans just how heavily we depend on public services in our day-to-day lives. There are many services that we as citizens tend to take for granted, hardly even recognizing that these facilities are publicly funded and crucial to maintaining a functional society. Airports, for example, are among our most-utilized public facilities, with somewhere around 100,000 flights scheduled to take off on any given day. Many hospitals also receive public funding, which is used to treat millions of patients suffering from a variety of ail-

ments. And of course, the more obvious public spaces, like police stations and courthouses, allow us to uphold laws and oversee legal proceedings— processes made more efficient with modernized spaces. Given the importance of public buildings, it stands to reason that these spaces have to be kept in optimal condition. Airports or hospitals that aren’t properly maintained could pose safety and health risks to both staff members and visitors, while poor conditions in other public facilities could lead to less utilization, and thus, diminished capability to uphold necessary proceedings.

A rendering depicting LAX’s Midfield Satellite Concourse facing west.

On The Gangway Given how frequently consumers and government officials visit airports, it’s no surprise that the buildings are often in need of renovations. The Los Angeles International Airport (LAX) in Los Angeles CA is one facility facing major refurbishments as part of a $14 billion Capital Improvement Program intended to modernize the space. The project is purportedly the largest public works program the city has seen, having started in 2009 and expected to continue through 2023. Since construction began, LAX has already added a new terminal, the Tom Brady International Terminal (TBIT), which opened to the public in 2013. There are still some major additions to the project underway, however, including a $5.5 billion Landside Access Modernization Program (LAMP) and a $1.6 billion Midfield Satellite Concourse. The LAMP program is intended to streamline the traffic entering and exiting the airport, allowing flyers traveling to and from the airport by car to experience a quicker and easier commute. As part of this pro64 Sound & Communications February 2019

gram, LAX will build a 2.25-mile Automated People Mover (APM) that will attach three of the airport stations to metro and transit services. A rent-a-car center, improved roadways and additional parking spaces are also listed as components of LAX’s LAMP initiative. Meanwhile, a total of 12 new gates will be built into LAX’s Midfield Satellite Concourse. The North Gates portion of the Midfield Satellite Concourse is expected to be completed later this year, and a Baggage Optimization Project (BOP) will take place alongside of it. A $515.8 million renovation of Terminal 1 and a $573 million renovation of Terminals 7 and 8 were also recently completed. The revitalized terminals now boast a more modernized design with improved security and luxury areas. In terms of security, new checkpoints have been added to Terminal 1, as well as baggage-scanning technology and baggage-claim areas. Terminals 7 and 8 have also been upgraded with more comfortable seating options in their waiting areas, as well as an increase in charging stations.

John F. Kennedy International Airport (JFK), located in New York NY, is also under renovation, with Mott MacDonald overseeing the initial engineering and design portion of the project. As part of JFK’s redevelopment, two new international terminals will be added to the facility. These terminals alone will span four million square feet, and their construction is scheduled to begin during 2020. If all goes as planned, the airport will start opening its new gates to the public during 2023, with the project being completed fully in 2025. In addition to the new terminals, JFK

also intends to redesign its roads and parking areas, as well as expand its connections to railways and mass transit. Given that it’s one of New York’s busiest airports, the focus on easing the commute to and from the facility makes sense. JFK will also see new security features, including radiation detection and tech-driven identification of unattended packages, and upgraded luxury areas for passengers awaiting their flights. In total, the project should amount to around $13 billion once it is finished. According to Gov. Andrew Cuomo’s office, $12 billion of the project’s costs will be funded through private investmen

‘Patch Up’ Projects Though airports comprise some of the largest-scale public renovations currently underway, they aren’t the only facilities being overhauled. Boston MA-based Massachusetts General Hospital is undergoing some major renovations in the near future, with plans to add a $1 billion addition to its campus currently in the works. The expansion would include two 12-story towers on Cambridge St., which are intended to meet increasing demands for high-quality and efficient patient care. Upon completion, the two new towers should allow the hospital to treat an additional 100 to 200 patients. In total, the building will amount to around

one million square feet. It will feature a heart center, a cancer center, 450 additional patient rooms and additional operating rooms. The new towers are expected to open in 2026, and the $1 billion price tag will likely be partially funded by the hospital’s donors. The Stewart Memorial Community Hospital (SMCH) in Lake City IA also unveiled expansion plans, which are intended to improve patients’ privacy needs, security and safety. The $31 million renovations will expand the emergency and rehabilitation departments, adding private exam and treatment spaces to both areas. The emergency room area will be relocated so that it is closer to the patient wing, and the hospital plans to streamline traffic by separating the emergency traffic from the main driving areas and adding a landing area for helicopters. As of this writing, the hospital has yet to announce the architect for the project or the expected completion date. The majority of the project’s price tag, however, is expected to be covered by the United States Department of Agriculture (USDA), with any remaining costs being picked up by local bank loans and contributions from the community.

Order In The Court Harrisburg PA is one city currently building a new federal courthouse, which will be located at Sixth St. and Reily St. The project remained in the development stages for several years, but the groundbreaking ceremony took place last June, and the facility is currently undergoing construction. The 243,000-square-foot building is expected to cost around $190 million when it’s finished, but the city expects the facility to bring in at least $300 million during the site’s development. There has been some controversy when it comes to the workers hired for the project, with the general contractor, Mascaro Construction Company, receiving backlash after it was revealed that most of the contractors on the project come from outside of the Harrisburg area. The courthouse construction is scheduled for completion by the end of 2021, allowing citizens to begin using it at the beginning of 2022. Potential tenants for the facility include the Pennsylvania 3rd Circuit US Court of Appeals, the US District Courts, US Mashal Service, US Attorneys and US Bankruptcy Trustees. That list had yet to be officially confirmed by project leaders at the time of this writing. February 2019

We work with inventors and investors to create and deliver revolutionary product ideas to redefine the professional audio industry. Sound & Communications: Who are the inventors you’re seeking to partner with? What kind of specific help are you offering them in their product development? Inline Audio: Everybody we talk to seems to be carrying around a great idea...perhaps one that wasn’t considered the right brand fit, or one that was rejected because the idea was genuinely new and therefore risky. We work with our inventors to guide them through the entire launch process—from creating investment proposals, to optimizing their designs for efficient mass production, to market launch and beyond. Sound & Communications: What is different about Inline Audio’s approach to cultivating its investor network, and how does it differ from conventional tech incubators? Inline Audio: We take a different approach than other incubators by wanting to provide an alternative to the clichés prevalent in the startup world.

Research into the profiles of successful entrepreneurs identifies that they are typically middle-aged, with a decade or more of industry experience, and they have acquired the judgment and expertise to make them lower-risk propositions for investors. We see the combination of these two factors as providing compelling investment propositions. Sound & Communications: What is the first launch we can expect to see from Inline Audio’s “incubator”? When can we expect to see it? Inline Audio: The products that we incubate are confidential until launch, due to the legal considerations with public disclosure before filing for intellectual property protection. Plus, we like surprises! Our first incubated product range will launch later this year. Sound & Communications: Why is now a particularly ripe time for Inline Audio to emerge? Inline Audio: We see an industry more interested in incremental improvement and grabbing market share from competitors by, perhaps, tweaking a couple of features, rather than by pursuing new and potentially risky product ideas. What we don’t see is any new and radical ideas. So, we decided to take the initiative do something about the state of our industry. —Dan Ferrisi February 2019

Portrait Displays, LG Electronics Announce Calibration Support Portrait Displays, Inc., and LG Electronics announced CalMAN AutoCal (auto calibration) support for the 2019 LG OLED and select NanoCell TVs unveiled last month at CES. In addition to CalMAN’s AutoCal support, two new calibration features have been added to LG’s TV lineup for this year: customizable high-dynamicrange (HDR) tone mapping and a built-in video test pattern generator. Display color calibration is the process of fine-tuning the color settings on a television to make the colors more accurate and lifelike, optimizing the video experience and making films, TV shows and other media match the creator’s intent. HDR televisions, such as the LG OLED and NanoCell TVs, map the color gamut to provide rich and lifelike colors. The 2019 LG TVs are the first to provide customizable HDR tone mapping, and CalMAN 2019 will take advantage of that customizability. Customized tone mapping will offer color professionals, content providers, integrators and installers the ability to control how their TVs render HDR10 content. People will now be able to configure three separate custom HDR tone maps and corresponding roll-off points that are tied to specific HDR10 metadata values.

Symetrix Manages Dante System At Elon University Schar Center Elon University recently opened the Schar Center, the home of Elon Phoenix basketball and volleyball and many other major campus events, on its 636-acre campus located in the Piedmont area of central North Carolina. The new building offers a spacious entry atrium, a large practice gymnasium, locker room and team facilities, a hospitality room for social events and gatherings, and a 160,000-square-foot, 5,100-seat main arena. Audio & Light, Inc., designed and installed the arena’s sound system, which is based on a Dante network managed with three Symetrix Edge DSPs. A second sound system, based on a Symetrix Prism 16x16, serves the three locker rooms and the weight-training room downstairs. “We have been using Symetrix DSPs for at least five years and use them increasingly now that Dante has become prevalent in the industry,” Brian Cox, Audio & Light’s Installation Division VP,

According to John McCoy, IT Systems Analyst in Aviation with the city of Austin, “This install was easy to do, because the early preparations were done well and [ever ything was] ready for us. The cabling and other items were put in by Br yComm with the oversight of Benjamin Stewart,” who, he said, worked on a number of projects for the airport. Shaun Davis was also involved in this portion of the overall renovation. McCoy added, “He had to get the IT working together with the airport information system, plus the airport personnel [had] to know how to run it correctly.” Ver y shortly after the installation of the display, a historical weather event oc70 Sound & Communications February 2019

curred, which, unfortunately, took out the monitor that had been installed. Because of the severity of the weather event, the display’s seal was breached and water got into the interior. Happily, because of the simple but effective infrastructure put in place, it took staff members literally 10 minutes to replace the TV and get the complete system back online. Davis summed up a feeling that virtually ever y participant in this project— and in this stor y—expressed. He said that morale was high throughout and ever yone was a team player, focusing on getting the job completed. “We own whatever we do,” he concluded. “There’s a great deal of cooperation on this. We all work together, and, even if it’s not part of our job, we help other sections to get things done.”

who designed the Schar Center AV systems, reported. “Symetrix DSPs work extremely well with Dante, and Elon University has adopted Dante as their digital-audio-transport platform. We also like Symetrix DSPs’ sonic quality, and they’re really flexible in the way you can control things, what they can do and how they can route. Symetrix Composer is a very good software package, and Symetrix does a really good job with the user interface. It’s easy to configure third-party products in Composer, as well. I used the Linea Research network I/O modules that were already available in Composer to drop the amplifiers right in.” All inputs, including the Dante feed from the arena’s Yamaha console, come into the main routing/switching Edge, which sends it to the other two Edges via Dante. The second Edge DSP is for the north, south, east, and west concourses and auxiliary spaces, which include a donor presentation room, a couple of media rooms, and the restrooms and hallways. The third Symetrix Edge splits signals out for the arena amplifiers.

(main story continued from page 37) and there are no tall buildings near it,” Martin explained. “It’s a real target for lightning strikes.” The East County EOC’s equipment choices were initially laid out nearly five years ago, reflective of the time spans that government projects can cover. However, according to Bilar, a former AV integrator himself, equipment choices for EOCs tend to be based on what has worked in those environments before. “EOCs are not the place to experiment,” he cautioned. He also used a previous project he worked on for the city of Los Angeles CA’s EOC as a kind of template for Riverside County, scaling things to fit the latter’s size and budget. At the same time, however, he always kept future expansions and upgrades in mind, with provisions to “bag and tag” some of the cabling to be installed for future applications. Although the East County EOC will have its videowall filled out at some point in the future—there are also tentative plans to add other features to it—the facility, as it is, is more than equal to its tasks. Its copper-cable infrastructure is as robust as it needs to be, Bilar affirmed, noting that the installation techniques, such as quad shielding and extensive grounding, are as reliable as any networked infrastructure is. “As the events of the last several years have shown, EOCs are going to be used more, not less, and they will have to manage a lot more information in real time,” he obser ved. “This facility can do all that. The cabling and interfaces for future phases are already in place as part of my baseline design, so they just need to hang ’em and hook them up. It’s ready to do more when the time comes.” February 2019

Lectrosonics’ Antenna With Built-In Amp

Elite Screens’ In-Ceiling Projection Screen

Lectrosonics has released its ALP690, a high-performance UHF log periodic dipole array (LPDA) antenna with built-in RF amp, for use with wireless mic receivers or base station transmitters in location and studio production. The new antenna design delivers +4dBd of passive gain in a directional pattern to extend operating range, and an RF amp can be engaged to supply gain for overcoming signal loss in long coaxial cable runs. The ALP690 antenna is powered by DC bias inserted on the coaxial cable connected to the 50-ohm BNC jack. This power can be supplied by a Venue Series receiver, an active multicoupler or an inline BIAS-T. When no bias is applied, the ALP690 automatically switches via relays to function as a passive antenna so that the antenna can be used for receivers, as well as IFB or IEM transmission applications. RF amp gain, filter bandwidth and display brightness are adjusted with a membrane switch keypad and LED display on the control panel. Lectrosonics

(continued from page 26) that it is. When you start talking about resolutions of 4K, 8K and 16K, along with high dynamic range (HDR), the amount of data required for uncompressed video signals becomes unmanageable. SMPTE is in the process of looking for a mezzanine-level compression for 2110 that will make 4K more feasible. NDI uses a discrete cosine transform (DCT)-based visually lossless compression scheme that allows for many 3G, and a reasonable number of 4K, streams to travel across existing network infrastructure. Both HDBaseT-IP and SDVoE utilize visually lossless compression, especially for 4K transmission. And, as resolutions continue to increase over time, compression will become even more necessar y. One of the benefits of using

(continued from page 18) your clients and potential clients. I hope this article can also provide you with information that arms you with a rationale that will help you to help HoW leaders understand the value purchasing new technologies brings. In Part 2 of this series, we will examine the remaining list of valued technologies. I believe new technologies, when used correctly, can create the desired worship experience that addresses the needs of each audience. That is what I believe. Please tell me what you believe.

IP to move audio and video streams is that it opens up the number of sources and destinations that are available, and it makes accessing those streams from more locations possible. SMPTE 2110 uses multicast to make sources available ever ywhere on a dedicated network, although it requires quite a bit of configuration. NDI can use either multicast or unicast, but it also has autodiscover y and the ability to select named sources (not just IP addresses), which makes configuration easier. Neither HDBaseT-IP nor SDVoE requires a dedicated central switching matrix, unlike previous-generation AV setups, so scaling the number of inputs and outputs only involves adding additional network ports. In all cases, the ability to traffic more

signals, route them easily and have them travel over longer distances (using multiple switches) is a game changer for both industries. It’s clear that both the live production and the commercial AV communities have come to the same conclusion—the future of connectivity for audio and video signals belongs to IP. It solves too many problems to ignore. The answer to the question of which flavor of AVoIP or liveproduction IP protocols depends on many factors. There is no silver bullet for ever y installation. The good news is that all types of IP utilize the same network switches and cabling as traditional IT technology does; that makes it much easier to mix and match flavors of IP, as well as to scale effectively as demands for more functionality arise.

INDUSTRY POV: QUIETER IS HEALTHIER: SOUND ABSORPTION CAN BE A CRITICAL COMPONENT (continued from page 30) range of reflected sounds— from low pitch to high—is not absorbed evenly. Whereas higher speech frequencies are the easiest to absorb (due to shorter sound wavelengths), problematic mid frequencies and low frequencies are more difficult to absorb. Rooms with thin absorber panels will commonly have dull, booming speech. Generally, the thicker a fiber-based absorber panel is, the better are its abilities to absorb lower frequencies, which results in smoother overall sound in the room. To account for such effects, manufacturers have started to roll out a new class of absorber panel products, known as microperf (or microperforated) panels, which are nearly perfect for hospital

usage. Unlike fiber-based solutions, microperf panels don’t have particulate fallout or as serious frequency selectivity. And, because the panels are typically wood or aluminum, which don’t give the appearance of traditional acoustical absorbers, microperf solutions are increasingly showing up in architectural designs. Microperf wood panels are commonly used in auditoriums, building lobbies and corporate meeting rooms, where they act as “stealth” acoustical absorbers that help to control echo and reverberation. Microperf aluminum solutions are excellent for cleanroom and medical-area use; they absorb a wide range of frequencies, and they can be steam-cleaned whenever

needed—something that cannot be done with fiber- or wood-based panels. Microperf aluminum panels are most often used in drop-ceiling grids, where they can replace existing gypsum ceiling tiles easily. Having awareness of the unique noise and sound problems found in hospitals is a good first step in achieving “quiet wellness”; second is to have knowledge of the applicable sound-absorber products. Quieter hospitals are healthier hospitals. Suggested References “Noise Pollution: Non-Auditor y Effects On Health,” by Stephen A. Stansfeld and Mark P.

AUDIO ARTS + MASS TRANSIT = BART PLAZA: DOWNTOWN BERKELEY TRANSIT HUB’S CREATIVE AND ARTISTIC SOUL (continued from page 46) chitect, Office of District Architect, San Francisco BART District. The overall project sought to enhance multi-model transit access and capacity for pedestrians and bicyclists, with improved safety and security in the plaza and in the transit area. The utmost care was taken in all aspects of the design and execution, as Downtown Berkeley is one of BART’s busiest stations, with around 30,000 riders a day. With regard to technology, real-time information display systems (RTDs) help transit riders get where they need to go, displaying information for both the buses and the trains. Specifically, the display screens show the transit operators’ logos/modes of transportation and ser vice lines. Departure times are displayed in a consistent format that’s easy to read and clearly illustrated. Information is updated every few seconds, and the current time is always displayed on the screens. The page can scroll to subsequent ones, if needed. The associated components were included as part of a performance specification

in the plaza construction contract, and they took only a matter of weeks to install. However, given the scope of the larger improvement project, installation had to wait until all the demolition, underground, foundation and utility work had been completed. According to Smith, coordinating the scope of the RTDs with the plaza improvements presented a challenge. The equipment installation and configuration of the system was fairly quick, he said, because all the configuration and design of the system was already completed prior to construction. The hard wiring of the data lines and tying into the network connection were not as easy, however. The conduit, circuits and cables had to be installed and pulled so as not to impact any operations of the station or impede pedestrian circulation. The work had to be performed at night, during nonrevenue hours or at off-peak times. With regard to components, Peerless-AV XHB552 55-inch Xtreme high-bright outdoor displays were chosen, combined with Peerless-AV CL-ENCL68 small-form-factor enclo-

sures. The compact, sleek design combined the displays with the enclosures, allowing for nicer aesthetics and performance criteria to be met. According to Smith, “The displays can be located in direct sunlight without any glare; they are weather-tight and can operate in rain; and the brightness of the displays helps the legibility of the content and provides a better customer experience for transit riders.” The displays are driven by an Advantech DS-081 ultra-slim fanless digital signage player. The power requirements are 120V, with Cat6A cable routed to the network. The signage player points to a URL with the transit information for the plaza. Finally, for the AC Transit NextBus Displays, hardware is limited to two MB-961603-S/S NextBus Signs. The signs are self-contained, and they only need AC power to run. All communications are done via the General Packet Radio Services (GPRS) digital cellular system between the sign and the bus. The sign requires continuous AC power, which is supplied from a dedicated breaker.

GETTING UP TO SPEED FOR AN AVoIP FUTURE, PART 3: THE IT MANAGER AND YOU (continued from page 61) always require configuration. For instance, although Dante uses QoS, QoS only requires configuration as total traffic approaches maximum bandwidth utilization on a mixed-use network. At that stage, it is sometimes only necessar y to configure QoS for the audio clock, rather than for all the audio data. IT managers might want to know if the proposed methodologies use unicast (from one source to one destination) or multicast (from one to many). Not all network managers are comfortable with multicast on their networks, because it potentially increases bandwidth consumption and it’s thought to send the same content ever ywhere on a network. However, Internet Group Management Protocol (IGMP) snooping, which sounds like a bad thing, is actually a helpful method for IT managers to keep multicast traffic off portions of the network that do not have to receive the multicast data. Keep in mind that, even if IT managers

do not permit you to use their networks, some might allow you to use a virtual local area network (VLAN) if you provide insights on how the VLAN will (or will not) connect to the primar y corporate local area network (LAN). Some manufacturers voluntarily assist integrators in the conversations with IT to help facilitate the adoption of their solutions. AVoIP of fers numerous benefits as compared to traditional signal distribution, even if you have to create a dedicated network entirely separate from the enterprise. Although an independent network might require pulling new cable, switches and other devices, you will have better control over the configuration, while also reducing potential conflict with nonmedia traffic. And even if you do choose a “plug-and-play” solution on a dedicated network, continue to educate yourself about networking. After all, the AV/IT convergence is here, and technology changes occur frequently.

left the room. None of this technology is expensive or difficult to implement, and all of it relies on Internet of Things (IoT) wireless connectivity. AI is already migrating into our industr y, and a fully loaded AV control system implementation, like those seen at CES, will happen within the next five years. Of course, adoption of AI and voice recognition for control systems will raise some big security issues, given that any of those connected devices can be (and, indeed, have been) hacked. 2. Yes, 8K displays and televisions are really coming! It’s not a fad. Thanks to overcapacity in Asian display-panel manufacturing facilities and aggressive pricing, we will have multiple vendors that offer native 8K-resolution LCD and OLED displays at InfoComm within a year or two. And, no, it doesn’t matter that there’s virtually no 8K video content to watch at present. After all, our industry is transi-

tioning to 4K resolution for flat screens and LED walls, even though there’s not a lot of 4K content out there, either. Bear in mind that the image-scaling processors are so good in these 8K sets that even standard-definition video looks decent on these huge screens, thanks to another type of AI. Some companies have already figured out complete 8K video production, editing, storage and deliver y systems (NHK in Japan is leading the way here). To top it off, an 8K Association was announced at CES, which will promote, and educate ever yone about, this new format. 3. LED displays are taking over ever ything. You already know about finepitch LED tiles—they’re in ever yday use, and they have reached resolutions as fine as 0.8mm. Now, there’s a new batch of “mini” LEDs being used as direct-view displays, as well as backlights for large LCD panels. Several TV manufacturers

showed TVs with “mini” backlights at CES, offering more local dimming zones. It won’t stop there, either. One company previewed a 75-inch 8K TV with a “micro” LED backlight prior to the show. Micro LEDs are super-tiny chips that can almost match display pixels in size, providing high levels of illumination and creating a new class of emissive displays with high dynamic range (HDR) and super-saturated colors. I had discussions with a display analyst who said a major manufacturer of LCD panels now wants to exit that business and, going for ward, concentrate on mini and micro LED displays for TVs. LEDs have been steadily eroding market share for large-venue projectors, and they’re competing with tiled LCDs for videowalls. Eventually, they will replace both LCD and OLED technology for a clean sweep across the display board. It won’t happen tomorrow, but I predict it will happen in the next decade. 4. We’ll be more dependent on wireless than ever. I saw some really clever demonstrations of high-speed gaming, 4K video streaming and display connections,

Wandering In The Desert, Again The Consumer Electronics Show continues to be a harbinger for our industry in more ways than one. By Pete Putman, CTS ROAM Consulting LLC As I write this, it’s the second full week in Januar y and I’ve just finished sorting hundreds of photos and several dozen videos from the Consumer Electronics Show (CES, as ever yone formally knows it), editing them down to a manageable lot. From the time I first attended the show nearly two decades ago, CES has slowly evolved away from being an exposition of standalone high-tech gadgets to become more of a “World’s Fair” or lifestyle/technology concept show. Early on, the attractions for me were high-definition rear-projection televisions, advanced plasma display technology and a new crop of LCD televisions that promised full-HD (1920x1080) resolution. Back then, DVD was an established technology for standard-definition video, and blue laser HD formats (HD DVD and Blu-ray) had yet to make an appearance. Wi-Fi was still pretty slow. Tablets and smartphones didn’t exist yet, nor did video streaming. (VHS was still a viable format back then!) TV networks were slowly coming around to broadcasting in high definition. And all this technology was expensive. A good plasma TV in 2003 could set you back more than $10,000, and some models went for as much as $30,000. Rearprojection TVs weren’t much cheaper. Loaded DVD players cost hundreds of dollars, and a decent digital TV set-top box was north of $700. A gigabyte of solid-state memory was an expensive proposition back then. All these products infiltrated the commercial AV space, and, in a few short years, a new expression had been coined: “the tail is wagging the dog.” It meant that the path from technical innovation to mass-market adoption had been inverted, trickling up from consumer devices to eventual commercial adoption and installation. 84 Sound & Communications February 2019

A few sights from CES.

Fast-for ward to this year. We’ve blown by full-HD displays and TVs to ultra HD (4K), and, now, a new wave of 8K TV sets is hitting the market. LCD screens that are 42 inches, once considered “big,” are pipsqueaks. Now, thanks to super-low prices, 65 inches is becoming the norm for homes and classrooms. Home-theater projectors are giving way to 70-inch, 85-inch and 88-inch LCD and OLED TVs. The Blu-ray optical disc format matured to Ultra HD Blu-ray, but not many people care about it anymore, because they’re streaming full HD and 4K video from YouTube. That’s possible because of super-fast Wi-Fi that uses channel-bonding techniques. Now, 60GHz Wi-Fi, which has been lurking on the sidelines for years, is poised to go mainstream. And a 32GB flash memor y card or thumb drive can be had for less than $20. In fact, just about ever y piece of hardware shown at CES sells for bargain-basement prices, with the exceptions being exotic products like 98-inch 8K televisions or roll-up OLED TVs. More and more of these products now move through distribution as retail prices drop. And all of them will make their way into your upcoming AV installations as the lines continue to blur between the conference room and the living room. (After all, what are huddle spaces if not riffs on the family room or kitchen?) Here’s what you’ll have to think about this year: 1. Artificial intelligence (AI) is here, and its adoption is happening faster than you think. At CES, multiple TV manufacturers showed next-generation AI implementations that could remember the TV programs (continued on page 79)
