Abstract
AbstractThis paper proposes a method of carrying out stable sound acquisition even if the targeted sound source moves, by constraining the sensitivity of an adaptive microphone array using multiple fictitious sources. Although the adaptive microphone array can achieve significant noise suppression, the conventional one has a problem in that the desired sound degrades and the noise increases when the desired sound source moves. In our method, multiple fictitious sources are used to constrain the sensitivity to the sound acquisition range. This effect is confirmed by a simulation comparing the proposed method and conventional ones. © 2003 Wiley Periodicals, Inc.
