The 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.
The 3M™ E-A-Rfit™ Dual-Ear Validation System makes it easy to measure every employee's unique level of attenuation through hearing protection fit testing and helps take the guesswork out of managing compliance in your hearing conservation program.
- Make it easy to measure hearing protection attenuation
- Tests both ears simultaneously in less than 5 seconds
- Earmuff and Earplug testing capability
- Tests at 7 standard frequencies - 125Hz to 8000Hz
- Science-based, objective, quantitative testing
- Compliant with ANSI/ASA S12.71-2018
Hearing protector fit testing is a way to measure the amount of noise reduction, or attenuation, a hearing protector provides while it is being worn by a specific individual. This real-world measurement is referred to as a “Personal Attenuation Rating” or PAR.
3M recommends workers fit test their hearing protectors. So, like respirators, the worker can better understand the level of protection they can achieve with a properly fitted hearing protection.
