PROBLEM TO BE SOLVED: To provide a method for correcting a sounding body directivity which prevents a high frequency region from being indistinct even when a gain in the rear of a speaker becomes high in a delay sum array method.;SOLUTION: In the delay sum array method, a position of the sounding body is detected from output signals of a plurality of microphones. Output signals from a plurality of microphones near the sounding body (near microphone output signals) among the plurality of microphones are monitored by a frequency region. A direction of the microphone having the highest high region of a spectrum envelope of frequency characteristics among the near microphone output signals is detected as a front face of the sounding body. A difference from frequency characteristics of the other microphones is detected and corrected.;COPYRIGHT: (C)2002,JPO
