How do you know if your workforce is protected?

Protecting workers from hazardous noise levels is an ongoing challenge for many organizations. In fact, according to the U.S. Bureau of Labor Statistics (2010)*, the most commonly recorded occupational health issue in the manufacturing sector is permanent hearing loss. The success of your safety program depends on many factors and requires more than just offering hearing protection.

Individual Fit Testing Using F-MIRE

Using F-MIRE (Field Microphone-In-Real-Ear) technology, the 3M™ E-A-Rfit™ Dual-Ear Validation System generates a Personal Attenuation Rating (PAR) in under 5 seconds for both ears, taking into account the 7 standard measured testing frequencies.

  • Measures how well that earplug is performing on that person
  • Delivers a quantitative measurement of personal noise reduction for each employee
  • Can help identify whether or not the employee has adequate protection

The Right Protection for Your Facility

Get results you can trust. The 3M™ E-A-Rfit™ Dual-Ear Validation System measures the effectiveness of the hearing protection from inside the employee’s ear, providing accurate, quantitative results. And because you can simultaneously test both ears, you’ll have more time to educate employees on the importance of fit and compliance.

Employee-to-Employee Variability

To make sure they are getting the protection they need, you might want to know the Personal Attenuation Rating (PAR) of every employee. The highest-NRR earplug or earmuff won’t provide the expected protection if it doesn’t fit right or isn’t used right. Once you know each employee’s number, you’ll be on the way to yours: 100% confidence in your hearing conservation program. Every employee is different. Every job is different. Every ear is different. Finding each employee’s number will help you validate compliance and have assurance that their hearing protection is sufficient.

E-A-Rfit Program Documentation

E-A-Rfit™ Dual-Ear Validation System testing sessions produce a validation document that can be kept in each employee’s file, providing documentation of your commitment to training and compliance with OSHA hearing conservation program guidelines.

  • Features easy-to-read test results for both ears as well as testing history
