Noise Attenuation
APPROVAL: ISOtunes WIRED is tested and approved in accordance
®
with ANSI S3.19-1974 Specifi cations.
Frequency, Hz 125 250 500
Grand Mean Attenuation, dB 32.0 32.1 36.5
Standard Deviation, dB 5.8 5.1 4.6
The level of noise entering a person's ear, when ISOtunes
are worn as directed, is closely approximated by the difference between the
A-weighted environmental noise level and the Noise Reduction Rating (NRR).
Improper fi t of this device will reduce its effectiveness in attenuating noise.
Consult the enclosed instructions for proper fi tting.
Example:
1. The surrounding noise level measured at the ear is 99 dB.
2. The NRR of ISOtunes WIRED is 29 dB.
®
3. The noise level entering the ear is approximately equal to 70 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 gunfi re.
