Hocks Noise Filter®

It is an axiom of physics that we cannot

create or destroy energy. 

We can, however, convert it. 

 

The Hocks Noise Filter® converts sonic energy into thermal energy by means of compression acceleration.  The rise in temperature is so minute you will never notice it.

The filter, inserted into hearing protection, allows air and sound to enter the ear. The Hocks Noise Filter® is designed to reduce the intensity of sound waves, as the sound waves get stronger.

The wearer can carry on a normal conversation. The voice can be heard with a slight reduction of volume, while the background noise is filtered out to a greater extent.

The actual amount of noise reduction depends on fit (in the case of Noise Braker Standards), volume, and pitch (lower sounds are not reduced as much as middle to high sounds).  The louder the volume, the more noise is reduced.
