SOUND SOURCE DETECTION SYSTEM AND SOUND SOURCE DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/130789
Kind Code:
A1
Abstract:
In a sound source detection system (5), a microphone array (MA) mounted to a vehicle (3) and a sound processing device (10) are connected to be communicable with each other. The microphone array (MA) has eight microphones (M1-M8), and transmits a sound signal picked up by each of the eight microphones (M1-M8) to the sound processing device (10). The sound processing device (10) detects the presence or absence of a sound source of object sound around the vehicle (3) on the basis of the sound signal transmitted from the microphone array (MA). The sound processing device (10) outputs information indicating at least the presence or absence of the sound source to a display device (60) if the sound source has been detected.
