Title:
SOUND SOURCE SENSING DEVICE AND SOUND SOURCE SENSING METHOD CAPABLE OF DETERMINING LOCATION OF SOUND SOURCE
Document Type and Number:
WIPO Patent Application WO/2023/106575
Kind Code:
A1
Abstract:
A sound source sensing device capable of determining a location of a sound source by comparing four sound source sensors with each other comprises: the four sound source sensors disposed at the respective vertexes of a square and respectively sensing sound sources generated outside the square; a noise filter which removes noise included in the four sound sources; a selecting unit selecting a maximum sound source sensor closest to the location where the sound source is generated, from among the four sound source sensors, by using at least one of a sensing time and a sensing amplitude of each of the four sound sources, from which the noise has been removed; and a determining unit determining the location where the sound source is generated, by calculating an angle at which the sound source is input, on the basis of the maximum sound source sensor.
