3M™ E-A-Rfit™ Dual-Ear Validation System 393-1100

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.

3M™ E-A-Rfit™ Dual-Ear Validation System helps employers verify whether the hearing conservation product that a worker is using is providing adequate protection. This objective fit-testing system provides a personal attenuation rating (PAR) for each worker. In just seconds, it measures across 7 standard frequencies, quickly reporting whether their hearing protectors (earplugs, banded, or earmuffs) are effectively blocking the individual worker from potentially hazardous workplace noise. Once every employee’s personal attenuation rating is known, health and safety professionals can utilize this data to enhance their hearing conservation program. Simply having hearing protection available is not enough Employers commonly believe that they are protecting employees simply by making hearing protectors available and hope for a high level of compliance among workers to not only wear them but wear them properly. But even when hearing protector usage is high, many employees may still be exposed to excessive levels of noise. Failure to provide adequate protection can be due to several factors, such as employees choosing the wrong type or size of hearing protection or not wearing them properly. These failures can leave workers with a false sense of security that puts them at risk for noise-induced hearing loss. The 3M™ E-A-Rfit™ Dual-Ear Validation System helps take the guesswork out of knowing whether workers are receiving the level of protection they need. Using this system is a simple three step process: 1) Fit - Have the employee fit the hearing protection test probes to both ears 2) Test - Connect to microphones and begin the speaker test sound 3) Assess - Use personal attenuation rating (PAR) to customize hearing protector selection
