Abstract:
A device for determining a sound source direction determines a direction in which a source of a reached sound exists, based on at least one of a sound pressure difference between a first sound pressure that is a sound pressure of a first frequency component of a first part of the reached sound acquired by a first microphone and a second sound pressure that is a sound pressure of the first frequency component of a second part of the reached sound acquired by a second microphone, and a phase difference between a first phase that is a phase of a second frequency component of the first part of the reached sound and a second phase that is a phase of the second frequency component of the second part of the reached sound.

Claim (Index 9):
The device according to  claim 1 ,\n wherein the sound pressure difference is a sound pressure difference average value, which is an average value of a plurality of frames of the sound pressure difference for each frame obtained by subtracting a logarithm of power of the second sound pressure from a logarithm of power of the first sound pressure, wherein the phase difference is a phase difference average value, which is an average value of a plurality of frames of the phase difference in a target frequency band for each frame, wherein the processor determines that the source of the reached sound exists at a position opposite to the first surface in at least one case of the case where the sound pressure difference average value is larger than a fifth threshold value and the phase difference average value is larger than a sixth threshold value, wherein the fifth threshold value is an average value of the sound pressure difference average value when the source of the reached sound exists at a position opposite to the first surface and the sound pressure difference average value when the source of the reached sound exists at a position opposite to the second surface, and wherein the sixth threshold value is an average value of the phase difference average value when the source of the reached sound exists at a position opposite to the first surface and the phase difference average value when the source of the reached sound exists at a position opposite to the second surface.
