3M Hearing Protection Fit Testing

Measure every employee's unique level of attenuation and take the guesswork out of managing your hearing conservation program.

Hearing protector fit testing is a way to measure the amount of noise reduction, or attenuation, a hearing protector provides while it is being worn by a specific individual.

This real-world measurement is referred to as a “Personal Attenuation Rating” or PAR. 3M recommends workers fit test their hearing protectors. So, like respirators, the worker can better understand the level of protection they can achieve with a properly fitted hearing protector.
