( N R R )
The Environmental Protection Agency (EPA) has selected the Noise Reduction Rating (NRR) as
the measure of a hearing protector’s noise-reducing capabilities. 3M makes no warranties as
to the suitability of the NRR as a measure of actual protection from any noise level since such
protection depends on the sound level (loudness), how long you listen to the loud sound and
how well you fit the earmuff over your ears. Although hearing protectors can be recommended
for protection against harmful effects of impulse noise, the 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.

The NRR for the Peltor
™
Tactical 100 Hearing Protector is 22 dB(A). Improper
fit of this device will reduce its effectiveness in attenuating noise. Consult
the enclosed instructions for proper fit.
The level of noise entering a person’s ear when a 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 (dBA).
2. The NRR is 22 dB(A).
3. The level of noise entering the ear is approximately 70 dB(A).
CAUTION
For noise environments dominated by
frequencies below 500 Hz, the C-weighted
environmental noise level should be used.
The NRR used in the above example was
achieved under laboratory conditions.

AUDIO INPUT LEVEL
The audio level in the hearing protector is dependent on the audio input level. To prevent
harmful noise levels, the hearing protector audio level is limited to 82 dB(A) when connected
to a Personal Music Player (PMP). If the hearing protector is connected to a PMP or other
device with a very high output level, it is the user’s responsibility to set the audio input level to
a safe level. The maximum permitted audio input level for 8 hours of usage time, compressed
speech and music is 188 mV.
