Fit testing is key for effective wear and hearing conservation. The 3M™ E-A-Rfit™ Dual-Ear Validation System accurately quantifies each wearers personal attenuation from inside both ears when wearing earplugs or earmuffs. Our system takes only seconds to measure across 7 standard frequencies and gives a simple pass or fail rating for each employee’s personal attenuation rating (PAR) to facilitate training on the importance of fit.
Fit testing is key for effective wear and hearing conservation. Get fast, clear, accurate and quantified data on the effectiveness of your hearing protection with our 3M™ E-A-Rfit™ Dual-Ear Validation System. The highest-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, you need to know the personal attenuation rating (PAR) of each one. Our 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 the 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 programme. Once measured you can determine if the protection they’re using the right hearing protection and ensure they are trained on using it properly. We engineer our hearing protection to be validation compatible by probing the plugs and earmuff cushions for use with the system. You can test the exact 3M hearing protection you use on the system and train on the actual products you use with specially probed versions. The kit is provided as a total system including software and is packed in a compartmentalised impact resistant carry case.
