New 3M E-A-Rfit Dual-Ear Hearing Protector Fit-Test Validation System
3M E-A-Rfit Dual-Ear Validation System measures a worker’s Personal Attenuation Rating with science-based, quantitative testing and helps employers identify the most appropriate hearing protection
ST. PAUL, Minn., — 3M Hearing Protection Solutions has announced its latest hearing protector fit test system to help combat hearing loss – the most commonly recorded occupational illness in manufacturing. The new 3M E-A-Rfit Dual-Ear Validation System measures the effectiveness of earplugs and earmuffs, providing accurate, quantitative results for both ears simultaneously. In less than three seconds, seven standard frequencies are measured for both ears, generating a Personal Attenuation Rating (PAR) to validate hearing protection and assist with hearing protector selection.
“The 3M E-A-Rfit Dual-Ear Validation System provides employers with the resources and confidence needed to better protect their workforce,” said Pegeen Smith, MS, RN, COHN-S, Technical Service Specialist. “The dual-ear system enables companies to quickly identify employees at risk for noise-induced hearing loss, assist in training employees, and help with hearing protector selection.”
While other systems typically rely on the employee’s subjective response to test signals, the 3M fit-testing system measures sound pressure levels objectively, both outside and inside the hearing protection. The test can be performed in relatively high levels of background noise. Results are not affected by the hearing level of the employee.
Once the measurement is complete, the software displays the PAR along with a pass/fail indication for the worker’s noise exposure level. The system helps ensure proper use of the hearing protection and identifies earplug or earmuff models offering the best protection, such as the popular 3M E-A-R Classic Earplugs or the 3M PELTOR Earmuffs X Series.
The 3M E-A-Rfit Validation System includes all the hardware and accessories needed, including a speaker, software, stand, dual-element microphones, cables and a trial quantity of probed test plugs.
