Cuts external background noise by up to 99.15%
Product was attached to an ear simulator centrally positioned between 5 noise-generating speakers (4 active speakers and 1 sub-woofer) while pink noise played at a cumulative level of 80dB. Ten (10) second recordings were made from the ear simulator with the DUT’s Active Noise-Cancelling (ANC) feature turned off and on. The measured noise attenuation was calculated and reported in support of the claim.
