The 3M EARfit Validation System is an objective, quantitative hearing protector fit-test system. It assists in achieving optimal fit through hearing protector selection and employee training. In less than 8 seconds per ear, the system generates a personal attenuation rating (PAR) that indicates a worker's noise reduction levels for a given fitting of a hearing protector. Compare ratings across hearing protectors and fittings to determine the best fit.
