Noise Attenuation
ISOtunes Sport ADVANCE is tested and approved in
accordance with ANSI S3.19-1974 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 Sport ADVANCE 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 attainable 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)
SafeMax™ Technology
ISOtunes Sport ADVANCE incorporates SafeMax™ Technology,
therefore its volume output has been limited to 85 decibels
(IT-36, IT-38), and 79 decibels (IT-39). ISOtunes® devices with
SafeMax™ Technology are OSHA, NIOSH, and ANSI compliant
and, when designated, meet the European Safety Standard EN
352.
Tactical Sound Control™ Technology
This product includes TSC - Tactical Sound Control or Aware
Technology. This is a microphone technology that allows
the user to hear the world around them, but always at a safe
listening level. When ambient noise breaches a safe listening
level, the microphone technology immediately responds and
attenuates to a safe level.
This feature automatically turns on when the product turns on.
Adjusting the TSC/Aware volume is easy. Simply press the TSC/
Aware Volume Up and Down Button.
