Hearing protection fit testing: Make it easy to measure hearing protection needs.
The 3M™ E-A-Rfit™ Dual-Ear Validation System makes it easy to measure every employee's unique level of protection in hearing protection fit testing and takes the guesswork out of managing compliance in your hearing conservation program.
What is the 3M™ E-A-Rfit™ Validation System?
E-A-Rfit is a service program designed to help validate hearing protection and compliance with hearing protection fit testing. It delivers an objective, quantitative measurement of each employee's protection, so you can better protect your workforce while helping employees understand the importance of proper fit. With the E-A-Rfit Dual Ear validation system, your employees will learn how to properly fit their 3M earplug or earmuff, and you'll have the confidence that they are wearing the right protection for their environment.

3M™ E-A-Rfit™ Dual Ear Validation System Training
In less than 5 seconds, the system generates a personal attenuation rating (PAR) that indicates a worker's noise reduction levels for a given fitting
Advantage: Reflects an individual's fitting methods and indicates if additional training is necessary in hearing protection fit testing.
The microphone measures the noise reduction of each earplug or earmuff as worn by the worker across the wide range of industrial noise frequencies.
Advantage: Objectively tests 7 frequencies (125 Hz - 8 kHz) in under 5 seconds per ear, so you don't rely on subjective test responses.
Patented system and proprietary algorithms quickly analyze real-ear data to provide Personal Attenuation Rating (PAR) and fit variability.
Advantage: PARs can assist in determining if the level of hearing protection your workers are getting is appropriate to their work environment.
Documented Results: Easy-to-understand test results are documented for each test subject, both in print and electronic formats, for future reference.
Integrating hearing protection fit testing into your hearing conservation program benefits everyone from new hires to high-risk workers.
