We were working with a customer recently that was in need of hearing protection here in our office. She wanted to know the difference in hearing protection/ear plugs that were available and why one over the other.
Hearing protection safety items have different noise reduction ratings or NRR. Noise Reduction Rating (NRR) is a unit of measurement used to determine the effectiveness of hearing protection devices to decrease sound exposure within a given working environment
The best out there today are the foam ear plugs, and I’m sure this comes as a surprise to many as she thought the ear muffs would provide the better protection. For example: foam plug NRR is 32, where the rubber Ultrafit is 25 and the muff device is anywhere from 20-25.
Depending upon your application, and your environment, there are several options to choose from. Regardless of the need, General Fire & Safety can assist in that process.
