Abstract:
A method for determining microphone position is a method for determining positions of a plurality of microphones in a microphone array having the plurality of microphones arranged in a plurality of concentric circles. The method for determining microphone position includes a constraint condition acquiring step of acquiring constraint conditions including the maximum number of the plurality of microphones; and a selecting step of selecting, from among a plurality of combinations of (i) the number of microphones included in each of the plurality of concentric circles and (ii) the radius of each of the plurality of concentric circles, a combination indicating directional characteristics with the smallest difference from a target value of the directional characteristics of the microphone array, where the plurality of combinations satisfy the constraint conditions.
