Title:
SOUND SOURCE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/042201
Kind Code:
A1
Abstract:
A sound source detection device (1) detects a prescribed sound source by comparing sound information collected by sound collectors (13, 14, 15, 16). The sound source detection device (1) is provided with a detection area determination unit (22) for determining a detection area for detecting a sound source by disposing each sound collector at equal distance from a noise source inside a moving body, and a sound source detection unit (25) for detecting the direction of the prescribed sound source using the sound information in the detection area determined by the detection area determination unit (22). Consequently, the sound source detection unit (25) does not treat sounds input into the sound collectors (13, 14, 15, 16) at the same timing as sounds to be detected, so it is possible to eliminate the influence of noise sources other than the sound source inside the moving body in advance.
