- Be careful not to drop your muffs as this may damage its components.

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.
Example:
- The environmental noise level as measured at the ear is 92 dBA.
- The NRR is 22 decibels (dB)
- The level of noise entering the ear is approximately equal to [92dB-22dB] Caution For noise environments dominated by frequencies below 500 Hz the C-weighted environmental noise level should be used.
