LIMITATIONS ON THE USE OF CIRCUMAURAL EARPHONES
Abstract
A literature survey and interpretation by a panel of experts of the NAS-NRC Committee on Hearing, Bioacoustics and Biomechanics shows that the now commonly-used large earmuffs, designed to protect hearing, cannot indiscriminately replace the small earphone cushion currently the standard for audiometry. If they are so used, hearing losses at 3000-8000 cycles/second should be rechecked with the standard cushion.
