NOISE REDUCTION RATING (NRR)
CAUTION: For noisy 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 AESEM1 Bluetooth
Earmuffs automatically default to 85dB when wirelessly connected
to a music device. If the hearing protector is either wirelessly
connected or wired 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 FEATURE DETAILS section for noise exposure
levels.
