Loud sounds can damage hearing, but wearing the wrong hearing protection can do the same. Do you know what level of protection your employees are receiving from their hearing protectors? Learn more about our quantitative method for hearing protection fit testing.
3M™ E-A-Rfit™ Dual-Ear Validation System uses a proven technique known as Field Microphone in Real Ear or F-MIRE to measure how well the hearing protector is working for each employee. The noise reduction provided by the hearing protector is measured directly and objectively, without the need for the employee to listen or respond to the test signals.

Hearing loss is 100% irreversible, but it’s also 100% preventable. And it starts here. Download the toolkit with literature and tools that help implement your hearing conservation program.
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 protector.
Hearing protective equipment is a Category 3 piece of PPE, like respiratory protection. If you fit test your respiratory protection, it would be good practice to fit test your other Category 3 PPE where equipment is available.
3M™ E-A-Rfit™ Dual-Ear Validation System uses a proven technique known as Field Microphone in Real Ear or F-MIRE to measure how well the hearing protector is working for each employee. The system test both ears in under 5 second across 7 frequencies. The noise reduction provided by the hearing protector is measured directly and objectively and provides and accurate quantitative assessment, without the need for the employee to listen or respond to the test signals.
When selecting the appropriate hearing protection it is key that they offer the best fit and meets the needs of the wearer. Use the Hearing Protection Advisor to help find the best solution for you.
Connect to the unique dual-element microphone
The microphone measures the noise reduction of each earplug or earmuff as worn by the workers across the wide range of industrial noise frequencies.
Advantage: Objectively tests 7 frequencies in under 5 seconds per ear, so you do not have to rely on subjective test responses.
