In 2017, Rojone purchased the design, manufacturing rights, and test equipment from Mobile One Electro Acoustics. This acquisition enabled the continued domestic production of the company’s High Noise Environment Headsets, Communication Leads, and consumable products. Over the past eight years, Rojone has made significant efforts to integrate the Mobile One Electro Acoustics designs into its ERP and Quality Management Systems. Simultaneously, we have been developing the necessary expertise to customise and service these components locally at our facilities in Ingleburn, NSW.
Through this acquisition, Rojone implemented production and quality processes improving manufacturability while maintaining the Australian standards and approval of the originally designed product. This move has also allowed us to maintain greater control over the quality and supply chain of our products. Our dedicated team has been working diligently to merge the innovative Mobile One Electro Acoustics designs with our advanced systems, ensuring seamless operations and enhanced product offerings. Additionally, our ongoing focus on building in-house knowledge has equipped us with the skills to tailor these components to specific customer needs and provide exceptional after-sales service, strengthening our commitment to local manufacturing and customer satisfaction.

WHAT IS AN SLC 80 Rating
The SLC80 Rating of a hearing protector, ear plugs or headset is a simple number and class rating derived from a test procedure outlined in the Australian/ New Zealand Standard, AS/NZS 1270: 2002. It provides a consumer with a simple number guide to the level of noise attenuation that can be expected from a particular hearing protection device (HPD). However, because we humans have heads that come in all shapes and sizes, some with or without eyeglasses, beards or long hair, the level of protection achieved for each person could be different. The SOUND LEVEL CONVERSION (SLC80) rating is the difference between the C-weighted sound level of the environment where the HPD is worn and the Aweighted sound level reaching the wearer's ears. The SLC value includes a mean minus one standard deviation correction to ensure that the stated degree of noise reduction is obtained on 80% of occasions. For this reason, it is called SLC80, and the 80 indicates the percentage protection rate.
The test procedure can be separated into two very different areas;
1) Mechanical Testing
Hearing protectors and headsets, like all things new, seem pretty good when worn for the first time; however, all things wear, headbands stretch, etc. To compensate for this wear factor and obtain a real-world test result, the HPD under test is pre-aged. This is done by subjecting the HPD to the effects of heat, cold, being dropped and having the headband flexed many times to simulate everyday use. The mass or weight is recorded and expressed in grams on the test certificate, which is the clamping force in Newton’s. This gives the user further information on which to base their decision on the potential overall comfort the HPD may provide. No one wants to work an 8-hour shift and feel as if they have a lead weight on their head or their head is in a vice.
2) Audiometric Testing
This is a subjective test; a minimum of sixteen (twenty for ear plugs) human test subjects are selected at random. Each subject is then given a hearing test to establish whether they fall into the "Normal Hearing" category, as outlined in the standard. The attenuation of the HPD is determined by measuring each subject's hearing threshold with and without the HPD fitted. The difference between these two thresholds is the so-called real-ear attenuation of the HPD. This is done by presenting each test subject with pulsed 1/3 octave pink noise of a known value at the following frequencies: 125, 250, 500, 1000, 2000, 4000 and 8000Hz and recording their hearing threshold. This data calculates the mean ear attenuation and standard deviation at each frequency
Subtracting the standard deviation from the mean gives us the mean minus standard deviation, which, when subtracted from the band level, provides us with the attenuation.
SLC80 Calculation
SLC80 Calculation 30.14 HMP-1 SLC80 30
Using the test data for our HMP-1 headset, the following formula is then applied: The SLC80 value is 100 minus the logarithmic summation of all the attenuated levels.
SLC80 = 100 – 10 Log10 (105.89 + 106.38 + 106.34 + 106.14 + 106.33 + 105.79 + 105.25) = 100 - 69.86 = 30.14, which is rounded to 30.
HPD is also given a class rating as outlined below once the SLC80 rating is known. CLASS SLC80, dB 1 10 to 13
It must be remembered that the SLC80 rating is not an exam mark where above a certain number you pass and below you fail; it is a means by which, in conjunction with the information contained in the Australian /New Zealand standard AS/NZS 1269.3:2005 Occupational noise management - Hearing protector program you can start to address the problems of hearing loss due to noise exposure for your given environment.
If you wish to gain a deeper understanding of the SLC80 rating or how to apply these ratings to your workplace, copies of the standards can be obtained from the following.
