NRR: 15 dB 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:
1. The environmental noise level as measured at the ear is 92 dBA.
2. The NRR is 15 decibels (dB).
3. The level of noise entering the ear is approximately equal to 77 dBA. 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 Mexico *This product is not manufactured or distributed by Cirrus Healthcare Products, maker of EarPlanes. 100% Satisfaction guaranteed with all Walgreens products or your money back. |
