The World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA) recommend maintaining environmental noises below 70 dBA over 24 hours (75 dBA over 8 hours) to prevent noise induced hearing loss.1 Directive 2003/10/EC of the European Parliament and of the Council of 6 February 2003 on the minimum health and safety requirements regarding the exposure of workers to the risks arising from physical agents (noise): Action level EC2 First action level (minimum) to provide protection Second action level: mandatory protection Daily exposure level LEX, 8h 80 dB(A) 85 dB(A) Peak sound pressure level LC, peak 135 dB(C) 137 dB(C) Accepted exposure level for 8 hours 85 dB + SNR 25 = Exposure value without protection for 8 hours 110 1 https://www.cdc.gov nceh hearing_loss what_noises_cause_hearing_loss.html 6 2 DIRECTIVE 2003/10/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 6 February 2003 Noise sources1 Jet plane take off, firecracker, gun shot Percussion section at symphony, air raid, jackhammer, power drill Ambulance siren, pneumatic drill, chain saw Leaf blower, power saw Motorcycle at 50 km/h, wood working, factory machinery Heavy goods vehicle at 50 km/h, tractor Handsaw, heavy traffic, noisy restaurant Manual machine tools, computer printing room Flush toilet, coffee grinder TV audio Alarm clock, electric shaver Call centers, offices, air conditioner, sewing machine Electric toothbrush Refrigerator Quiet residential area, library Soft whisper Ticking watch Noise level in dB 140 130 Health effects2 Pain and ear injury 120 110 Hearing loss possible in less than 25 minutes 100 Hearing loss possible after 15 minutes 90 Damage to hearing possible after about 50 minutes of exposure 85 Damage to hearing possible after 2 hours of exposure 80 Cardiovascular effects 75 70 Sleep disturbances 65 Stress, annoyance 60 55 50 Sounds at these dB levels typically 40 don't cause any hearing damage. 30 20 7 Performance counts 8 9 Phonak Serenity ChoiceTM Pro highlights at a glance Phonak Serenity ChoiceTM Pro, generic ear tip, exchangeable filter, lanyard Phonak Serenity ChoiceTM Pro Custom, full concha, exchangeable filter, lanyard Attenuates noise and loud sounds effectively Phonak Serenity ChoiceTM Pro significantly reduces noise and loud sounds, allowing you to work safely in noisy environments1.

The relative humidity of normal, healthy ears is between 40% and 70%1. However, lower humidity in the ear has been linked to a reduced chance of ear infections. Lab tests show that Serenity ChoiceTM Pro filters allow lower levels of humidity in the ear compared to a full block filter.

The generic product has a medical grade TPE (ThermoPlastic Elastomer) eartip and the custom product is a standard custom earshell made from silicone or acrylic. Each of these has a hearing protection filter inserted. The filter itself is made up of two main parts: the filter housing, available in different colors to distinguish between filter use cases; and a washer with mesh. For custom products made from acrylic, there is also a pressor with tag. This provides adequate seal and retention for the filter which enables an easy filter exchange process.

Contact your Phonak representative or check our website for a complete list of partners. Acoustic Leakage Tester (ATL) Verifying the fit and seal of custom earpieces is critical to ensure the correct attenuation performance of hearing protection. A leaky custom earshell reduces performance, making the user susceptible to hearing damage. Up until now, the standard ways to test for acoustic leakage were either by using test equipment which is large and complicated to use, requiring a noisy pump and air tubes or, more commonly, by performing audiometry. This method is relatively time consuming, requiring around 15 minutes for each earpiece. The Acoustic Leakage Tester (ALT) from Phonak not only simplifies this testing process, it is also fully portable and easy to use. You can use it to verify the fit and seal of custom (and generic) hearing protection in less than a minute. It runs on an iPod, iPhone or iPad, and you just need to press a single button for automated calibration and leakage measurement. 24 25 Getting the numbers right 26 27 Performance and costs comparison The actual purchase price of a hearing protection device doesn't take into consideration the costs over time, nor the advantages or disadvantages of a solution.
