Noise Attenuation

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 27 dB and a Noise Reduction Rating (NRR) of 21 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® Sport DEFY Slim 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:

1. The surrounding noise level measured at the ear is 100 dB.
2.  The NRR of ISOtunes® Sport DEFY Slim is 21 dB.
3. The noise level entering the ear is approximately equal to 79 db/

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.
EN 352

• 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 DEFY Slim incorporates SafeMax™ Technology, therefore its volume output has been limited to 85 decibels. ISOtunes® Sport devices with SafeMax™ Technology are OSHA, and ANSI compliant.
