Non-Linear Filter

Variable sound reduction is achieved using a non-liner filter inserting into a pre drilled canal on your custom plugs.  This filter attenuates as sound pressure increases, which causes the filter to restrict sound pressure (loudness) as it increases.  The non-linear filter also reduces the occlusion effect (blocked ear sensation) and allows you to percieve a more open ear or natural effect whilst wearing plugs. Also allows for easier communication.
