3M™ E-A-Rfit™ Dual-Ear Validation System helps determine whether workers are receiving adequate protection from their hearing protector by measuring across 7 standard frequencies in under five seconds, providing a detailed report on the noise attenuation performance of earplugs or earmuffs.
3M™ E-A-Rfit™ Dual-Ear Validation System helps determine whether workers are receiving adequate protection from their hearing protector by measuring across 7 standard frequencies in under five seconds, providing a detailed report on the noise attenuation performance of earplugs or earmuffs and a pass or fail rating for each individual person based on the employee's personal attenuation rating.
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 with data stored locally in the PC or, for data sharing, in the 3M Cloud. 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:
Fit - Have the employee fit the hearing protection test probes to both ears
Test - Connect to microphones and begin the speaker test sound
Assess - Use personal attenuation rating (PAR) to customize hearing protector selection
Features:
Dual-element, dual-microphone assembly is the key to the system, measuring sound levels inside and outside the hearing protector
Science-based, quantitative testing gives accurate reports of hearing protection
Optional Cloud enables stored centralized data, multiple fit testing systems operating simultaneously across sites, and access restricted to authorized users.
System determines personal attenuation rating (PAR) of individual workers and helps remove measurement, fitting, and spectral uncertainty
Dual-ear design saves time by measuring both ears simultaneously in under five seconds
System tests across 7 standard frequencies (125, 250, 500, 1000, 2000, 4000, 8000 Hz)
