Abstract
Disclosed is a sound source detection devicewhich compares information of sound collected by sound collectors, andto detect a predetermined sound source. The sound source detection deviceincludes a target determination unitwhich arranges sound collectors at the same distance from a noise source inside a mobile object to determine a detection-target region of a sound source, and a sound source detection unitwhich detects the direction of the predetermined sound source using information of sound of the detection-target region determined by the target determination unit. Accordingly, the sound source detection unitdoes not determine sound input to the sound collectors, andat the same timing as a detection target, making it possible to eliminate the influence of a noise source other than a sound source inside the mobile object in advance.
