The 3M™ E-A-Rfit™ Dual Ear Validation System makes it easy to measure every employee's unique level of protection and takes the guesswork out of managing compliance in your hearing conservation program.
Tests both ears simultaneously in less than 5 seconds.
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 that they are wearing the right protection for their environment.
It is Fast, quantitative and objective
Personal Attenuation Rating (PAR) of hearing protectors
Step 1: Workers self-fit their own earplugs or earmuffs.
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.
Step 2: Connect to 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.
Step 3: Run the Test for Personal Attenuation Rating (PAR)
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.
Look how well the 3M™ E-A-Rfit™ Dual Ear Validation System fits into your hearing conservation program. Integrating hearing protection fit testing into your hearing conservation program benefits everyone from new hires to high-risk workers.
Establish baseline values for new workers
Helps identify workers receiving inadequate protection that leaves them at risk of threshold shifts
Validate high protection levels required by workers in high noise areas
Fit, Train & Motivate
Provides tool for training proper fitting techniques and to assess proficiency
Motivates employees by helping them realize the control they have in protecting their hearing
Assess & Manage
Improves long term performance of your hearing conservation program
Indicates employees needing further fit training or alternative hearing protectors
Input your noise exposure data and the 3M™ E-A-Rfit™ Dual Ear Software can help you identify the most appropriate hearing protection and help minimize over/under protection
