E-A-Rfit™ Dual-Ear Validation System

How do you know if your workforce is protected?

Go To Hearing Protection Overview

Overview

  • The success of your safety program depends on many factors and requires more than just offering hearing protection. To make sure they are getting the protection they need, you need 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.
