Abstract:
A sound collecting apparatus capable of effectively suppressing sounds other than a target sound is provided. The sound collecting apparatus includes a plurality of microphones. A total number of effective microphone pairs in which a distance between two microphones is smaller than a distance D is larger than a total number of the plurality of microphones. The distance D is represented by D=c/2f, where the frequency of the target sound acquired from each of the plurality of microphones is f and sound velocity is c. When an angle formed by a straight line connecting two microphones configuring an effective microphone pair and a predetermined straight line is θ, the angles θ of all effective microphone pairs acquired from the plurality of microphones are different from each other.

Claim (Index 6):
The sound collecting apparatus according to  claim 1 , further comprising:\n a processor; and a non-transitory recording medium storing thereon a computer program, which when executed by the processor, causes the processor to perform operations including\n giving a delay to a voice signal acquired from each of the plurality of microphones to generate delayed output signals, \n generating a first signal by adding the delayed output signals, \n generating a second signal by performing subtraction on output signals corresponding to two microphones configuring the effective microphone pair among the delayed output signals, \n applying a filter coefficient to the second signal, \n generating a third signal by subtracting the second signal applied with the filter coefficient from the generated first signal, and \n updating the filter coefficient based on the third signal.
