Look out for this sign! The international symbol for telecoils and induction/hearing loops. It may vary in shapes and colours.

The idea of an assistive listening device People with hearing loss often get alienated and cut-off from the social setting. To be unable to take part in the social interaction between people is a dreadful experience and it tend to make them alone and unhappy. The single most important assistive device for people with hearing loss has been, still is and will be for the foreseeable future, the hearing aid. But the hearing aid alone, is not a sufficient tool for better hearing in every place and at every time. The idea of an assistive listening device is to assist whenever the hearing aid is not sufficient. In many cases the only way to increase speech intelligibility is to cut the distance between the sound source and the listener and at the same time reduce the surrounding noise. This can basically be achieved with the use of three different techniques – hearing loop, radio (FM) or infrared (IR) systems.

Why the hearing loop system? While FM and IR systems may have its advantages in certain personalized situations, only the hearing loop can bring sound to everyone, everywhere and at once without the need for an extra receiver. The hearing loop uses the built-in receiver in the hearing aid (T-coil) to transmit the sound without background noise through the personally adjusted hearing aid. Without any extra receiver and without any extra power consumption, the hearing aid user can experience crystal clear sound free of disturbing noise – without even telling anyone about their hearing loss. They just switch their hearing aids to T-position and enjoy the sound. To bring back this freedom to the hearing aid users has always been the most important goal for us.

Everyone wins In a public area the hearing loop is clearly the best option for the hearing aid user. We believe it's also the best solution for the owner of the venue. Although a loop system might demand a little more commitment at the start, it will pay back many times over. A loop system is always active and can facilitate for everybody as it's not limited to the number of receivers you have. With a minimum of maintenance it's also the most cost effective solution. In environments where people are just passing through, a loop system is the only practical solution.

Creating accessibility in public areas Many people haven’t heard of hearing loops and have no idea of how much it can help to compensate for hearing loss. All public spaces benefit from an assistive listening device and according to us, the best way to make larger venues audio accessible to all, is to install a loop system that covers the entire listening area. Venues already equipped with a sound system can easily be connected to a hearing loop. Theatres, cinemas, auditoriums, conference rooms, houses of worship, arenas, schools... All of these public spaces, whether they are old or new, can be fitted with loops. Univox loop systems’ high quality audio with perfect, clear and crisp sound, bring out the fine nuances and details needed for a great experience.

Theatres, cinemas & concert halls The sound of music • Auditoriums • Reception • Ticket sales • Elevators

One of the main applications for hearing loops are venues like theatres, cinemas and concert halls. They are built just to enjoy sound and vision. There is an amazing difference for the hearing impaired to be able to hear everything with a clear sound. And with a loop installed there is no need for extra receivers being requested, handed out, returned, checked and cleaned. These venues all benefit from loops placed in segments along the seating rows, so a hearing impaired visitor can be seated anywhere and still be guaranteed audibility. This type of loop configuration is almost unaffected by the influence of metal and maintain a stable field strength and frequency response throughout the hall. (Read more on SLS, page 13 and 26.)


Stockholm Concert Hall, Sweden

A well designed series of loop systems has made every single seat in the Stockholm Concert Hall available to the hard of hearing community. The audio quality is perfect where ever you sit thanks to the Univox systems that transmit both horizontally and vertically.

Copenhagen Opera House, Denmark

In the Copenhagen Opera House’s main stage, loops were installed in a specially designed configuration. Whenever the size of the orchestra space is changed, the loop sections switches automatically on/off.


Conference and meeting Join the conversation! • Meeting room • Boardroom • Conference • Auditorium

Your audio system in meeting rooms or conference halls should be accessible to all, including the hard of hearing. The Univox loop system serves the purpose to include your colleagues, clients or business associates with hearing impairments, so everythings that’s said and agreed upon is understood by all participants.

Installed loop system For auditoriums and larger meeting areas we offer loop systems covering all seats. Connected to existing sound systems, the loop acts as an assistive listener and your venue is accessible to all.

Portable loop system

All you need – a complete loop kit!


Univox Portable Loop System has everything a venue owner or a meeting organizer needs to set up a professional multipurpose temporary loop system. You will have a mobile system that fulfils any demand for accessibility and matches the expectations of your hard of hearing guests.

The UN City complex, Denmark

The UN City complex Three auditoriums and three meeting rooms in the Copenhagen UN City complex are equipped with installed hearing loops to accommodate the staff and visitors with hearing aids. With a delicate hand, the right segment size is designed to attenuate the overspill enough not to disturb the users of the adjacent loop system.

Nordkalotten Conference, Sweden

Nordkalotten Conference In the very north of Sweden, Nordkalotten conference center has installed hearing loops in several auditoriums. In the crescent-shaped main hall, the loops follow the curved seating rows and create a fully covered listening area.


Houses of worship Hear every word!

St. Leonard’s Church, United Kingdom

In houses of worship the acoustic is often compromised by the echoes and background noise. This is particularly difficult for hard of hearing people. With a loop installed the visitors are able to listen to a sermon with clear sound and high intelligibility. • Churches • Synagogues • Mosques • Temples • Similar premises

St. Leonard’s Church Nestled in the picturesque Somerset village, St. Leonard’s is a charming rural parish church commanding beautiful views over the surrounding countryside. As part of a project to modernize and conserve the building, it was decided to upgrade the existing PA and install an hearing loop system for hearing aid users. The challenge to modernize historic facilities is to do so without ruin the ancient atmosphere of the place. The acoustic challenge for this particular church was the echoes and reverberations from the naked middle age stone walls. The simple but yet so effective solution was a standard perimeter loop configuration, perfectly calibrated, providing crystal clear sound. All wiring were completely concealed, keeping the middle age atmosphere of St. Leonard’s church intact. 8

The Cardboard Cathedral, New Zealand

The Cardboard Cathedral The Cardboard Cathedral in Christchurch, New Zealand, a transitional pro‑cathedral of the Anglican Church, opened in August 2013. It seats around 700 people and also serves as a conference venue. It’s made by cardboard tubes, timber, reinforced concrete and steel. Given the heavily reinforced concrete slab in the area where the loop was being installed, an SLS design was the best solution. The design offers a very uniform field strength level across the listening plane.

The Haci Hasan Mosque, Turkey

Depending on the material and layout of the hall, both perimeter and SLS loops are options. The cable can be hidden and the loop amplifier can be connected to the sound system already in place. Just a small signage by the door will tell your visitors that a loop has been installed and that everyone is welcome to enjoy.

The Haci Hasan Mosque The Haci Hasan Mosque is situated in the city of Eskisehir, in Central Anatolia, Turkey. It was originally built in the 13th century and is a beautiful example of Seljuk architecture. The Haci Hasan Mosque was restored and redesigned to be the first mosque in Turkey fully accessible to all disabled groups and reopened for worship in 2012. This was also the first mosque in Turkey to be looped and to our knowledge the first in the Muslim world. The mosque has received much attention from local and national Turkish media and hard of hearing people from all around the city come specifically to this mosque because of the loop.


Crowds of people yelling and cheering... An excited and intense atmosphere... Also a complete noise blur to the hearing aid wearer.

Sport arenas Keep up! • Seating in arenas • Ticket windows • Elevators • Conference facilities

In a looped arena it is not only easier to get the appropriate information, for example in emergency situations, but also to follow and enjoy the game. When covering every seat you prevent the hearing aid users to be referred to a designated section, separated from friends and family. Instead they have full accessibility to the event on the same terms as everyone else.

The National Museum of Art The National Museum of Art in Stockholm was looking for a guide system which could serve both people with hearing aids and to make the guided tours easy to hear for all. The guides themselves also needed a better work environment to avoid having to talk so loud.


The museum chose the Univox Okayo wireless tour guide system. Thanks to the extra high output power of the pocket transmitters, the system can be used with both earpiece/headset and neck loop for the people wearing hearing aids.

Museums and exhibition Great guiding

Wireless Tour Guide System The wireless tour guide system helps to overcome the problems with the distance between guide and audience in noisy surroundings. Our wireless pocket transmitters and receivers can be used both as conventional guide systems as well as assistive listening devices for guests with or without hearing aids.

Installed loops Installed loops in auditoriums or smaller areas with video or audio installations are also areas that should be taken into consideration. Connect the loop to the existing sound system and you will create accessibility for the hearing aid users. By giving them a crisp and clear sound instead of noisy reverberations, they can enjoy the show to the full.

The Hearing Loop System – How does it work? Induction

Step by step

Most hearing aids have a built in T-coil, a small wireless receiver, in addition to the regular microphone. When a current passes through a wire (the loop cable), a magnetic field is generated around it. If a coil (the telecoil in the hearing aid) is brought within this magnetic field, a corresponding current is created. In technical language, the current is induced in the second wire, hence the term ”induction loop” which is another name for hearing loops. This electro-magnetic principle is the basis for hearing loops and the T-coil technique was invented in the 1950’s.

The hearing loop driver is connected to the source of the sound, e.g. an audio system. The loop driver transforms the signal into an electric current in a loop cable surrounding the listening area. The loop current sets up a magnetic field which fluctuates with the audio. When the hearing aid is switched on to the T-mode, the T-coil will pick up the signal from the magnetic field and convert it back into audible sound. The sound is clear and crisp and tailored for the individual’s hearing loss.

Hotels It’s all about service!

• Reception • Conference • Elevator

Reception Welcoming your hotel guest should be easy and smooth. For a hearing disabled guest to be able to communicate, it is important to have an efficient and easy to use hearing system installed. An across the counter system at the information desk, ensures clear conversation between the guest and the staff, directly transferred via a microphone and a small hearing loop to the guests hearing aid. (Read more on page 12.) Conference For the conference facilities, both installed and portable loops are options for making your hotel accessible to all. The loops can be placed in meeting rooms with adjustable walls and in several adjacent rooms without interference. (Read more on page 6.) Elevator Make the stay even easier by installing loops in your elevators. Loops contected to the intercom system assist the hearing impaired guest both when using the elevator in normal circumstances and in cases of emergency, such as fire alarms.


Scandic Victoria Tower, Kista, Sweden

Scandic Hotels In 2005 Scandic Hotels implemented a program to make their hotels completely accessible to guests with all types of disabilities. Some tasks were aiming at solving the problems for hearing impaired guests. They needed better audibility at the reception desks, audio access in the conference rooms and a safe way of being alerted both for waking up and in case of fire alarms. Together with Univox, all Scandic hotels in Sweden, Norway, Denmark and Finland were equipped with cross the counter loop systems for the reception desks to enable better communication, and portable loop systems for their conference facilities. They were also provided with SafeWake clocks, which alert by vibration, even when the fire alarm goes off. Several Scandic hotels in Germany, Poland, Netherlands and Belgium have the same equipment. New Scandic hotels are ever since equipped with the same “basic kit�.


Transportation Barrier free travelling In the context of assistive listening, transport represents a wide range of applications from coverage on board vehicles to transportation hubs such as airports and train stations where waiting rooms, platforms, departure gates, help desks and even intercom systems in lifts and car parks will require hearing loop coverage. Univox has solutions designed for use on board a variety of vehicles, including trains, trams, metro, buses, coaches, taxis, cars, boats and lifts. Where required, the induction loop amplifiers have been designed to meet appropriate transport EMC and safety requirements. For transport hubs such as train stations and airports, we have solutions suitable for one to one applications and systems covering public spaces and waiting areas – everything to enable barrier free travelling.

Airports Good audio communication is fundamental to the smooth running of an airport. However, where speech is the main means of communication, the sound environments are often particularly difficult for the hearing impaired. • Check-in desks • Passport control desks • Security points • Currency exchange counters • Intercom systems - help points, ticket machines and lifts • Waiting areas by each gate (connected to PA/VA) • Gate desks • Shopping areas

Hearing loops, that are active around the clock, can make the travelling much easier for the hearing aid users. Melbourne Airport, Australia Melbourne Airport, also known as Tullamarine Airport, is the primary airport serving the city of Melbourne, and the second busiest airport in Australia. All gate areas in Pier G are fitted with loops. Due to the heavily metal reinforced structure – common in most airports – a Univox SLS design was preferred to achieve even field strength and adequate frequency response. Now the travellers can hear their flight info loud and clear.


Metro, trams and light rails

• Platforms • Passenger Information System on board • Information desks • Ticket windows • Elevators

Metros, trams and light rails are increasing all over the world. As urban areas grow, more people rely on swift, secure and comfortable public transportation every day. The awareness among train builders, architects and operators about the challenges that disabled people are facing while travelling, is increasing. Decision makers are taking this into account when designing trains, stations and associated facilities. The focus of these efforts is almost always on granting access to wheelchair users and other people with reduced mobility, yet this group is only a small percentage of the total number of disabled people. The largest group by far, the hearing impaired, is almost always forgotten. The sound through the speakers is very difficult to hear even for a normal hearing person. To install a loop makes a great change for the hard of hearing. Hong Kong Metro The MTR Corporation opened the first metro line in Hong Kong 1979. The current system have five lines running over 218 km through 155 stations. Millions of people are on the move every weekday, making it one of the most heavily utilized mass transit systems in the world.

Hearing impaired had difficulties in receiving information, both at the service centres and at the platforms, due to a very high noise level. Univox hearing loops where installed and are now serving the hard of hearing community daily.

Buses and coaches Many people refer to the signage and displays on the public bus, but unfortunately a considerably large group of the hearing disabled also have impaired vision. Not being able to hear when your stop is coming up or communicate with the bus driver, makes the travelling much harder than it has to be. Univox loop systems for integrating with the existing sound system is an excellent utility for the guided tour as well as for the city bus, allowing hearing aid users to access the information they need. We also offer restricted loops for direct communication with the driver. The Univox amplifier is designed to operate in these environments. Our compact amplifiers are small, powerful and efficient (with the smallest carbon footprint in class) and comply with the relevant automotive standards.

• Information on the bus • Cross the counter • Ticket windows • Waiting areas


Trains With a loop system on board, the hearing impaired passengers get direct access to call outs, safety alarms and information transmitted by the Passenger Information System (PIS). Their journey will be safer, easier and more relaxing, especially when travelling alone. A hearing loop system is the most practical, least expensive and lowest maintenance solution to providing quality access to on-board audio information for the hearing impaired.

• Platforms • PIS on the train • Information desks • Ticket windows • Elevators

As always when installing loop systems on-board rolling stock, there are a number of technical obstacles: Attenuation of the magnetic field due to the metal in the cars, magnetic background noise from braking systems and electrical cables, available electrical power, interface to the PIS, vibrations, temperature variations, dust and cramped installation space. All these challenges have to be overcome by choosing the right mix of power, loop design, loop wire placement and of course – the right loop driver for the job. With a robust construction of the amplifier, including dust coated PCB, glued capacitors and dip-switch settings of all levels, the Univox transportation amplifier is designed to work in these conditions.

Direct access to call outs, safety alarms and information.

NSB, Norway

Norwegian railway When NSB invested in 75 five-part electrical trains, a vital concern was to find an appropriate loop system to be integrated with the Passenger Information System (PIS). Some of the trains were long local versions for the S-Bahn traffic in the Oslo area, with travelling times of up to 90 minutes. Others were regional trains covering the area of Southern Norway with travelling times of up to 3 hours. These different traffic conditions and the high ambition of user friendliness for disabled travellers along with the harsh Norwegian climate, posed a real challenge.

The NSB train cars had advanced thermal and acoustic insulation to fulfil the high requirements needed for winter operation in Norway. This proved to be an advantage for the installation. Careful attention was given to the design of the ceiling loop and after thorough testing of the loop system in an actual carriage, pre-set conditions for all input and output levels were established. Following a close collaboration with both train manufacturer and PIS supplier, 375 train cars were equipped with hearing loops, completely covering each train car.

Taxi and transportation service Taxi Even for a normal hearing person, communicating with a taxi driver can be difficult, given the high background noise in the traffic environment and the fact that the driver is facing forward, sometimes even behind a screen. Imagine then the situation for the hearing impaired. To cover a taxi with a loop system makes a lot of sense and the small, efficient loop amplifier from Univox, directly connected to the car’s 12V power system, makes all the difference. Transportation service For wheelchair users or other physically impaired people using a transportation service in a larger vehicle, hearing the driver may prove impossible. To cover the transportation service vehicle with a loop system makes the transport both safer and more pleasant, allowing for a personalized service. 21

Health care

Home environment, wards and infirmary

Solutions for life

In the realm of social welfare and public health we have become increasingly aware of the need for hearing loops in the homes of hearing aid users, and in many countries these assistive listening devices are available free of charge or on a subsidized basis. A hearing loop offers many advantages. At home or in a ward, the listener doesn’t have to sit close to the TV or radio, or put the volume up to the breaking point. Instead, the listener can be seated anywhere in the room, or even move around, and still hear as well. Perhaps the greatest advantage is that the sound comes pure and undistorted directly into the ear, not affected by any interfering background noise. Once having a hearing loop installed at home, it’s easily arranged for the telephone or the doorbell to also be transmitted over the hearing loop.

• Home environment • Wards and infirmary • TV lounges • Nursing homes • Apartment hotels • Homes for the elderly

Low spill The field generated by the loop is threedimensional. It extends above and below the level of the wire and also beyond the boundaries of the loop and into adjoining spaces. This is reduced by using SLS figurations, where the loop is placed in segments, to minimize the overspill.

Home for the elderly, Kontula, Finland

Home for the elderly 48 loop systems were installed in a home for elderly people in Kontula, Finland, resulting in all public areas were made accessible: dining rooms, cafeterias, TV rooms, gyms, meeting rooms, chapel and several halls. As the rooms often were either adjacent or above/ below each other, SLS loop systems were required throughout the house. The exceptional overspill control built into the SLS system made it possible to finalize the installation successfully with a signal-to-noise ratio good enough to allow simultaneous use of the loops.

22 22

For any other space or for outdoor use, a portable loop system was provided, giving them freedom to make excursions.

Hospitals Being able to communicate in an emergency can be vital. At the hospital, hearing loops at the reception and in waiting areas are simple tools to facilitate the situation. Drugstores and counters where specifics needs to be clarified, also clearly benefit from assistive listening devices. And for the doctor or the nurse, a portable loop might be the solution when checking on the patients. Just bring the loop to the bedside! At the hospital as well as in any public space, it’s essential that everyone is addressed when it comes to security and alarm systems. In case of fire alarms, emergency situations, elevator failures all of the intercom communications can be connected to the loop systems.

• Reception • Doctors’ offices • Dentists • Doctor´s rounds • Waiting areas • Elevators • Drugstores The loops enable easy call outs in waiting areas.

23 23

Classrooms An important period in children’s lives is to acclimatize and get familiar to school. Being able to hear and understand is essential to lay the ground for all future learning and socializing. Class rooms where children with hearing impairment can follow the lesson, improves their chances considerably.

School and university Education to be heard

Hearing loss is increasing, even among younger people

• Classrooms • Auditoriums • Dining rooms • Gymnasiums

Although it’s quite common amongst the elderly, a great number of young people also suffers from hearing loss. In addition to those born with it, headphones, loud live music and a constant stream of high background noise, have unfortunately increased the number of children becoming hearing impaired. This is very concerning and will probably grow even more in the future. These young people must be taken into account when planning new schools, universities and other venues.

Auditoriums Integrated with the existing sound systems in auditoriums, loops grant access to the hearing impaired. Without the inconvenience of announcing their disability, students can immediately join the lecture.
