Introduction
Thank you for purchasing ISOtunes® AIR DEFENDER professional noise isolating headphones. These headphones have been specifically 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.
Noise Attenuation APPROVAL
This product has been tested to the European Safety Standard EN352-1:2002 and
the ANSI S3.19-1974 standard for a hearing protector, with a Single Number
Rating (SNR) of 30 dB and a Noise Reduction Rating (NRR) of 24 dB. Full
testing details are available in the Noise Attenuation section of this
booklet.
ANSI
S3.19-1974
The level of noise entering a person’s ear, when ISOtunes®
AIR DEFENDER headphones 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:
- The surrounding noise level measured at the ear is 100 dB.
- The NRR of ISOtunes® AIR DEFENDER is 24 dB.
- The noise level entering the ear is approximately equal to 76dB.
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.
EN352
- 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)
