  • Technique for localizing sound source
    Patent number: 9319785
    Abstract: Disclosed is a technique for localizing a sound source. In the technique, a sound pressure signal measured by microphones is acquired using a spherical microphone array sensor where the microphones are fixedly arranged on a surface of a spherical body. A sound pressure distribution on the surface of the spherical body is obtained by a controller from a sound pressure calculation formula for calculating a sound pressure at a certain location of a spherical surface using the sound pressure signal measured by the microphones as an input value. A location of the sound source is estimated from the obtained sound pressure distribution.
