Easy Insertion Forms To Ear Canal Shape EPA Now Softer for More Comfort Noise Reduction Rating: 29 Decibels (when used as directed) The range of noise reduction ratings for existing hearing protectors is approximately 0 to 30 (higher numbers denote greater effectiveness.) Information Required By EPA: The level of noise entering a person's ear, when a hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. (1) The environmental noise level as measured at the ear is 92 dBA. (2) The NRR is 29 decibels (dB). (3) The level of noise entering the ear is approximately equal to [92 dB(A) - 29] 63 dB(A).
