Hearing protection headsets can be made acoustically transparent to the user if environmental sound can be easily localized. A proposed array of microphones processed by a filter-and-sum technique can recreate the target head-related transfer functions. A three-dimensional numerical model of a KEMAR mannequin with headset was experimentally verified to a 12-kHz bandwidth. The optimal six-microphone array (three per headphone) was measured in an anechoic chamber, and preliminary subjective tests were encouraging.
