The 3M E-A-Rfit Dual-Ear Validation System determines whether workers are receiving adequate hearing protection by measuring 7 standard frequencies in under five seconds, generating a detailed report on the attenuation performance of the earplugs or earmuffs, and giving each worker a pass or fail based on their personal attenuation rating.attenuation performance of the earplugs or earmuffs and issuing a pass or fail for each employee based on their personal attenuation rating.
- The objective bilateral hearing test takes just a few seconds for 7 standard frequencies
- The two-sided design saves time, measuring ears simultaneously in under five seconds
- The two-element, two-microphone design is an important part of the system and measures noise levels inside and outside the hearing protector
- Fast, clear, accurate results in just seconds that can be printed or stored electronically for future reference
- The system determines each worker's personal protection factor (PAR) and provides measurement and fitting confidence and spectral safety
- Requires test earplugs
- Includes software, speaker and durable transport case
