Quantitative Fit Testing of Hearing Protection

Environmental controls, hearing protectors, and on-the-job training are the first steps to protecting your workers against noise-induced hearing loss (NIHL). Take the next step with Fittest.ie Validation System, an objective, quantitative hearing protector fit-test system. We are now offering Quantitative Fit Testing of Hearing Protection to our customers. Using New Acoustic fit testing Technology we are now able to establish the Personal Attenuation Rating (PAR) achieved when wearing hearing protection. As part of compliance with the Control of Noise at Work contained in the SH&W (General Application) Regulations 2007 employers must ensure appropriate Hearing PPE is provided where engineering controls cannot reduce the noise levels sufficiently. Integrating hearing protector fit testing into your hearing conservation program benefits everyone from new hires to high-risk workers.

Noise is one of the harmful and arduous factors appearing at work places. Taking into hear consideration safety and comfort of your employees we have implemented a new service which provides proper selection of hearing protectors. The service is based on 3M E-A-Rfit™ Validation System which considers specific factors appearing at work place and also individual characteristic of employee (i.e. ear build)

Main role of this service is to counteract loss or aggravation of hearing.


It is implemented in 3 steps: 

Step 1: Workers fit plugs themselves 

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 

Advantage: Reflects an individual’s fitting methods and indicates if additional training is necessary.

Step 2: Unique dual-element microphone

The unique dual-element microphone measures the noise reduction of each earplug as worn by the worker across the wide range of industrial noise frequencies.

Advantage: Objectively tests 7 frequencies (125 Hz - 8 kHz) in under 8 seconds per ear, so you don’t rely on subjective test responses.

Step 3: 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.
