Information required by E.P.A. (US)
The level of noise entering a person's ear, when
hearing protectors are worn as directed, is closely
approximated by the difference between the A-
weighted environmental noise level and the NRR.
For example:
1. The environmental noise level as measured at
the ear is 92 dBA.
2. The NRR is 29 decibels (dB).
3. The level of noise entering the ear is approxima-
tely equal to 63 dBA.
Caution: For noise environments dominated by
frequencies below 500 Hz, the C-weighted en-
vironmental noise level should be used. Improper
fit of this device will reduce its effectiveness in at-
tenuating noise. Consult the enclosed instructions
for proper fit. 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 conti-
nuous noise and may not be an accurate indicator
of the protection attainable against impulsive noise
such as gunfire. Constant or repetitive exposure
to impulsive noise may lead to serious injury,
including temporary or permanent deafness. The
Noise Reduction Rating (NRR) calculated from the
attenuation data is 29 dB. Earplugs must be fitted
to attenuate noise effectively. Refer to instructions.

Hearing protector class 5 tested to AS/NZS 1270. When selected, used and main-
tained as specified in AS/NZS 1269, this protector may be used in noise up to 110dB(A)
assuming an 85 dB(A) criterion. A lower criterion may require a higher protector class.
