SOUND SOURCE SEARCH APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sound source search apparatus which is hardly affected by a background noise, and can perform source localization with high accuracy without performing complex signal processing. SOLUTION: The sound source search apparatus 1 includes: a plurality of differential microphones 10 with bi-directionality; and a supporting member 20 which supports the plurality of differential microphones 10 so that the plurality of differential microphones 10 are aligned in an array on the same plane. The plurality of differential microphones 10 are supported by the supporting member 20 so that the main axis with bi-directionality is substantially vertical to the same plane.
