NOISE ISOLATION POLAR PATTERN Noise isolation is the measure of sound attenuation levels achieved with A10 earphones that have been properly fitted in the ear canals with the supplied silicone ear tips. The noise isolation polar pattern illustrates how attenuation of the A10 earphones varies as a function of both frequency and direction of the sound source. In general, lower frequencies are less attenuated than higher frequencies and sound sources coming the side of the head are less attenuated than from the front or back. Audix earphones do not carry a Noise Reduction Rating and are not meant to be used as a hearing protection device.
