NRR Information
Although hearing protectors can be recommended for protection against the
harmful effects of impulsive noise, the Noise Reduction Rating (NRR) is based
on the attenuation of continuous noise and may not be an accurate indicator of
the protection attainable against impulsive noise such as gunfire. 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.
