NOISE REDUCTION RATING (NRR)
CAUTION: For noise environments dominated by frequencies below 500
Hz, the C-weighted environmental noise level should be used.
NOTE: 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 continuous noise and may not be
an accurate indicator of the protection attainable against impulsive noise
such as gunfire. The Environmental Protection Agency uses the Noise
Reduction Rating (NRR) as a rating of a hearing protector’s noise-reducing
performance. Klein Tools cannot guarantee the suitability of the NRR as a
method of rating protection as protection relies on the level and exposure
of sound and how well a product fits.
AUDIO INPUT LEVEL
The audio level in the hearing protector is dependent on the audio input
level. To prevent harmful noise levels, the AESEB1S SMART SENSE
Situational Awareness Bluetooth
®
Earbuds automatically default to
85dB when connected to music device. If the hearing protector is
connected to a music device with a high audio output level, it is the
user’s responsibility to set the audio input level to safe level. See table in
WARNINGS section for noise exposure levels.
