3M Dispenser Base

The 3M dispenser base is a dual microphone assembly for measuring sound level inside and outside the hearing protector and gives accurate reports of hearing protection. This system concludes personal attenuation rating (PAR) of every worker and helps to remove measurement, fitting and spectral insecurity.
