The level of noise entering a person's ear, when ISOtunes PRO
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.
Example:
1. The surrounding noise level measured at the ear is 97 dB.
2. The NRR of ISOtunes PRO ™ is 27 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 gunfire.
