Introduction
Thank you for purchasing ISOtunes® LINK Professional Noise
Isolating Earmus. These earmus have been specically
designed for use in noisy environments – allowing you to block
out much of the surrounding noise so that you can listen to your
music or talk on the phone with less interruption. This product
has been tested and meets the European Safety Standard
EN352-1:2002, EN352-8:2002 and the ANSI & NIOSH standards
for a hearing protector, with a Single Number Rating (SNR) of 36
dB with a Noise Reduction Rating (NRR) of 27 dB. Full testing
details are available in the Noise Attenuation section of this
booklet.
Noise Attenuation
APPROVAL: ISOtunes® LINK is tested and approved in
accordance with ANSI S3.19-1974 Specications and the
European Safety Standard EN 352-1:2002 and EN352-8:2002.
ANSI
S3.19-1974
The level of noise entering a person’s ear, when ISOtunes®
LINK headphones are worn as directed, is closely approximated
by the dierence between the A-weighted environmental noise
level and the Noise Reduction Rating (NRR). Improper t of this
device will reduce its eectiveness in attenuating noise. Consult
the enclosed instructions for proper tting.
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® LINKis 23 dB.
3. The noise level entering the ear is approximately equal to
77dB.
Please note that the 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 gunre.
EN352
The EU declaration of conformity can be accessed at www.
isotunes.co.uk/EU-declaration-of-conformity.
The products will be certied to the Product standard EN 352-
2:2002 and the PPE Regulation 2016/425.

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)
