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 decibels dB(A).
  2. The NRR is 33 decibels (dB).
  3. The level of the noise entering the ear is approximately 59 dB(A).

Noise Reduction Rating 33 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).
