Information required by E.P.A. (US)
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 25 decibels (dB).
3. The level of noise entering the ear is approximately equal to 67 dB.
Caution. For noise environments dominated by frequencies below 500 Hz the C-weighted environ-
mental noise level shall be used.
Warning. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hear
-
ing protectors can be recommended for protection against the harmful effects of impulsive noise,
NRR is based on the attenuation of continuous noise and may not be accurate indicator of the
protection attainable against impulsive noise such as gunfire.
