    Details

    The 3M™ E-A-Rfit Dual-Ear Microphone Assembly, 073-781 works with the 3M™ E-A-Rfit Dual-Ear Validation System to help employers determine whether workers are receiving adequate hearing protection from their hearing protector. The complete system issues a pass or fail rating for each individual based on the employee's personal attenuation rating (PAR). Each dual-element microphone connects to probed test plugs, test pods or cushions and measures sound pressure levels inside and outside the hearing protector.
