Five years in development, the Hocks Noise Braker® is a device that suppresses noise to a safe hearing level, while allowing important, normal conversation to be heard.
The Hocks Noise Braker Filter® converts sonic energy into thermal energy by means of compression acceleration.
You can still hear, but a dangerous level of sound can not possibly get through the filter.
The Noise Braker® is a filter.
As such, it lets air and sound through. The Noise Braker® is designed to reduce the intensity of sound waves, as the sound waves get stronger. The wearer can carry on a normal conversation. The normal voice can be heard with a slight reduction of volume, while the background noise is filtered out to a greater extent.
