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.
EN 352
The product has been tested and approved in accordance with PPE
standards: EN 352-2:2002, EN 352-7:2020, EN 352-9:2020 and EN
352-10:2020.
RED
The product has been tested and approved in accordance with RED
Standards: ETSI EN 300 328 V2.2.2 (2019-07), EN 62479:2010, ETSI
EN 301 489-1 V2.2.3 (2019-11), ETSI EN 301 489-17 V3.2.4 (2020-

Hereby, Haven Technologies declares that the personal protective
equipment ISOtunes PRO Aware is in compliance with the Regula-
tion (EU)2016/425 and the electrical circuit and radio equipment is in

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
