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 11):
The device according to  claim 9 ,\n wherein an average value of the sound pressure difference average value when the source of the reached sound exists at the position opposite to the first surface and the sound pressure difference average value when the source of the reached sound exists at the position opposite to the second surface is an average value of a first average value, which is an average value of a first speech section of the sound pressure difference, and a second average value, which is an average value of a second speech section of the sound pressure difference, wherein a difference between the first average value and the second average value exceeds a second predetermined value, wherein an average value of the phase difference average value when the source of the reached sound exists at the position opposite to the first surface and the phase difference average value when the source of the reached sound exists at the position opposite to the second surface is an average value of a third average value, which is an average value of a third speech section of the phase difference and a fourth average value, which is an average value of a fourth speech section of the phase difference, and wherein a difference between the third average value and the fourth average value exceeds a third predetermined value.
