Sound energy reaches the cuff and is directed away from the ear into the chamber. High decibel sound waves are dampened, refracted and cancelled. The chambers are tuned to create an even reduction in sound across all frequencies. Communication and Safety Are Key Hear the useful sounds in your noise environment.
