Hearing protection must provide the correct amount of sound attenuation (dampening) to keep workers' hearing in the safe zone, while still allowing these employees to perceive warning signals. Over-attenuation should be avoided.
All Phonak's static hearing protection systems provide uninterrupted noise attenuation, and their supplied acoustic filters provide fully customizable levels of protection.

Our passive (or 'static') systems are designed for use in continuous loud noise. Serenity SP is fully, enabling the user to click their ear shells into other Serenity products. Silemo Mini suits offices and clean workplaces.
