Hearing fit-test system


The 3M E-A-Rfit Dual-Ear Validation System measures the effectiveness of earplugs and earmuffs. In less than three seconds, seven standard frequencies are measured for both ears, generating a Personal Attenuation Rating to validate hearing protection and assist with selecting hearing protection. The system includes a speaker, software, stand, dual-element microphones, cables and a trial quantity of probed test plugs.
