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 18):
The computer-readable non-transitory recording medium according to  claim 17 ,\n wherein the sound pressure difference is an average value of a sound pressure difference 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 an average value of phase differences of a target frequency band, and wherein the procedure determines that the source of the reached sound exists at a position opposite to the first surface in at least one case between a case where an average value of the sound pressure differences is larger than a first threshold value, which is a plus value, and a case where an average value of the sound pressure differences is larger than a third threshold value, which is a plus value.
