Earplug Noise Reduction Ratings Explained

Earplug Noise Reduction Ratings Explained

This means that if you are at a rock concert with a level of noise exposure at 100 dB and you are wearing a hearing protector with an NRR 33 dB, your new level of noise exposure is 87 dB. If you are wearing a product with an NRR of 27 it would deduct 10 decibels (277/2=10). *To maximize noise reduction, hearing protectors must be worn properly.
