The level of noise entering a person's ear, when hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Example: The environmental noise level as measured at the ear is 92 dBA, the NRR is 32 decibels (dB), the level of noise entering the ear is approximately equal to 60 dBA. Noise Reduction Rating 32 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). 1-866-786-2353 Made in USA 100% Satisfaction guaranteed with all Walgreens products or your money back. |
