ISOtunes PRO AWARE Manual De Instrucciones página 12

signed to protect against harmful noise – allowing you to block out
much of the surrounding noise so you can listen to your music or talk
on the phone with less interruption. This product has been tested
and meets the ANSI standards for a hearing protector, with a Single
Number Rating (SNR) of 33 dB and a Noise Reduction Rating (NRR)
of 26 dB. Full testing details are available in the Noise Attenuation
section of this booklet.
Noise Attenuation
ISOtunes PRO Aware is tested and approved in accordance with
ANSI S3.19-1974, EN 352-2:2002, EN 352-7:2020, EN 352-9:2020, and
EN 352-10:2020 Specifications.
ANSI
S3.19-1974
The level of noise entering a person's ear, when these earbuds are
worn as directed, is closely approximated by the difference between
the A-weighted environmental noise level and the Noise Reduction
Rating (NRR). Improper fit of this device will reduce its effectiveness
in attenuating noise. Consult the enclosed instructions for proper
fitting.
A1: Frequency (Hz)
A2: Mean Attenuation (dB)
A3: Standard Deviation (dB)
Example:
1. The surrounding noise level measured at the ear is 100 dB.
2. The NRR of ISOtunes PRO Aware is 26 dB.
3. The noise level entering the ear is approximately
equal to 74dB.
Please note that the NRR is based on the attenuation of continuous
noise and may not be an accurate indicator of the protection attain-
able against impulsive noise, such as gunfire.

B1: Frequency (Hz)
B2: Mean Attenuation (dB)
B3: Standard Deviation (dB)
B4: Assumed Protection Value (APV) (dB)
B5:
H = Hearing protection estimation for high frequency sounds
(f ≥ 2000Hz)
M = Hearing protection estimation for medium frequency sounds
(500 Hz < f < 2000Hz)
L = Hearing protection estimation for low frequency sounds
(f ≤ 500Hz)
Criterion level is the sound pressure level in dB(A) of the noise en-
vironment resulting in 85 dB(A) effective to the ear while wearing
hearing protectors. Three different criterion levels are defined related
to the frequency content of the noies.
C1: H = criterion level for high-frequency noise
C2: M = criterion level for medium-frequency noise
