What is the Noise Reduction Rating (NRR)?

The Noise Reduction Rating (NRR) is a measurement of the number of decibels (dB) that ambient noises are reduced by when a device is used correctly.

This rating is provided to allow the consumer to find hearing loss prevention devices that will offer them the proper amount of Noise Reduction based on their typical environments noise level.

All of our New Line Plugfones as well as our Plugfones Yellow have been rated with a Noise Reduction Rating of 25 dB. This rating matches or surpasses the ratings of traditional earplugs. For more information please visit our Noise Reduction Ratings (NRR) Page.
