CAUTION.

For noise environment dominated by frequencies below 500Hz, the C-weighted environmental noise level should be
used. Improper fit of this device will reduce its effectiveness in attenuating noise. Although hearing protection can be recommended for protection against the harmful effects of impulse noise, the Noise Reduction Rating is based on the

attenuation of continuousnoise
