INFORMATION REQUIRED BY E.P .A.
The level of noise entering a person's ear, when hearing protection is worn as directed, is closely approximated by the difference between the
A-weighted environmental level and the NRR.
Example: 1. The environmental noise level at the ear is 100 dBA.
2. The NRR is 22 decibels (dB).
3. The level of noise entering the ear is approximately equal to 78 dBA.
!
For noise environments dominated by frequencies below 500 Hz, the C-weighted environmental noise level should be used.
Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing protectors can be recommended
for protection against the harmful effects of impulse 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 impulse noise, such as gunfire.
WARNING!
NOTE: The Noise Reduction Rating is derived from testing procedures at an independent laboratory and in accordance to acceptable A.N.S.I.
standards. Actual noise reduction can vary from laboratory results as labelled. Protection is maximized when: proper protector is selected for
application, a good training program is utilized and proper fitting techniques are followed.
