While allowing clear transmission of 2-way radio communications and maintaining workers' ability to enjoy stereo audio entertainment, Heavy Vehicle Communication Solution (HVCS) also intelligently limits unwanted and potentially harmful environment noise. Solution targets heavy vehicle operators and decreases exposure by 10 dB or more. When combined with smartHeadsets and smartPlug wireless headsets, solution also protects wearer by electronically limiting in-ear noise exposure at 82 dB.
