3M Hearing Protection Solutions has introduced the E-A-Rfit dual-ear validation system. The hearing protector fit-test system measures the effectiveness of earplugs and earmuffs, providing quantitative results for both ears simultaneously. In less than 3 sec., the system measures seven standard frequencies, generating a personal attenuation rating (PAR) to validate hearing protection and assist with hearing protector selection.
The 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.
The system includes all the hardware and accessories needed, including a speaker, software, stand, dualelement microphones, cables, and a trial quantity of probed test plugs.
