Elvex Cap Mount Ear Muff For Hard Hats Universal Bracket NRR 27db

• NRR rated to 27 db
• Consists of two 27 decibel muffs and two arms with universal slot adaptors; fits in the universal slots found above the ears on the outside of most hardhats

• The universal slot adaptors also have the narrow opening to take a visor bracket like our VB10

• The ability to put a visor bracket like VB10 in the slot adaptor means your hardhat can also hold a set of muffs and a visor (to hold a face shield)

QUESTION: What is meant by Noise Reduction Rating? ANSWER: That is the number of decibels by which the hearing protector will reduce the noise. For example, if you are working in an environment with a noise level of 90 dB, a protector with 27 dB NNR (Noise Reduction Rating) will reduce the noise 27 decibels. Scientifically that is a lot more than it appears, because every time you reduce noise levels by three decibels it is like cutting it in half.
