Fit testing is key for effective wear and hearing conservation. The 3M™ E-A-Rfit™ Dual Ear Validation System accurately quantifies personal attenuation from inside both ears when wearing earplugs or earmuffs. The system takes only seconds to measure across 7 standard frequencies and gives a simple pass or fail rating for each personal attenuation rating (PAR) to facilitate training on the importance of fit.
- System provides fast, clear, accurate fit testing of hearing protection as quantified scientific data
- Personal attenuation rating (PAR) is first step in fit testing and hearing conservation program
- Measures sound levels inside and outside of the earplug in only 5 seconds
- Results can be printed or saved electronically for future reference
- Packed in sturdy, compartmentalised, impact-resistant carry case
- System uses specially adapted hearing protection with probes
- Test and train on standard hearing protection for most effective results
The highest-rated SNR earplug or earmuff won’t provide the expected protection if it doesn’t fit or isn’t used correctly. To make sure your team are getting the protection they need, the personal attenuation rating (PAR) of each team member is required. This system saves time as the dual microphone measures both ears at the same time. The process is extremely quick and easy, taking only five seconds to measure the dB protection inside both ears. The software is seamless to integrate, and results can be printed and saved electronically for future reference and comparisons. Finding employee’s PAR is the first step in a successful hearing conservation program.
Once measured you can determine if the protection employees are using is the right hearing protection, and ensure they are trained on using it properly. 3M engineers this hearing protection to be validation compatible by probing the plugs and earmuff cushions for use with the system. The kit is provided as a total system including software and is packed in a compartmentalised, impact-resistant carry case. The system includes software, speaker, and carrying case. Requires probed test plugs, pods, or cushions. Free online training and user support is also available.
