Noise Reduction Rating (NRR) - Custom Molded Earplugs

Noise Reduction Ratings (NRR) have been tested by an independent third-party lab.

Noise Reduction Rating with foam tips: 31

Noise Reduction Rating with silicone tips: 24

THE NOISE REDUCTION IS DEPENDENT ON THE FIT OF THE EARPLUGS. TEST YOUR EARPLUGS IN PROGRESSIVELY LOUDER ENVIRONMENTS BEFORE ENGAGING IN ANY ACTIVITY THAT COULD CAUSE HARM 

What is Noise Reduction? 

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. Decibullz are one of the highest rated custom-molded earplugs available!

*The EPA has selected the Noise Reduction Rating as the descriptor of hearing protector effectiveness to be utilized on the labels required by U.S. EPA Regulation 40 CFR Part 211 Subpart B. Decibullz makes no warranties as to the suitability of NRR as a measure of the actual protection afforded to the individual user.
