The 3M E-A-Rfit Dual-Ear Microphone Assembly 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.
