E-A-Rfit™ Dual-Ear Validation System

E-A-Rfit™ Dual-Ear Validation System Overview

The 3M E-A-Rfit is a service program designed to help validate hearing protection and compliance. 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 knowing that they are wearing the right protection for their environment.

The 3M™ E-A-Rfit™ Validation System is easy to operate. 

1. Workers self-fit their own earplugs or ear muffs
   
   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.
    
2. Connect the unique dual-element microphone
   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.nnect to the unique dual-element microphone
    
3. Run the test for Personal Attenuation Rating (PAR)
   
   Patented system and proprietary algorithms quickly analyse 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.
