How do we know a sound level is safe?
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

= Exposure value without protection for 8 hours 110

Why is it important to `let the ear breathe'?
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.

Construction is key

19

A unique simple, flexible and reliable construction
In the illustrations below, we can see how Serenity ChoiceTM is constructed. 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.

How we serve you and your workforce
Our extensive service network is always on hand to take ear impressions and to test custom hearing protection devices. 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.
