The sound generator position acquisition system, sound generator position acquisition manner, the sound reflected element in order to generate the specific delay deformation which corresponds to the relative position with the formation mannered

摘要

PROBLEM TO BE SOLVED: To make it possible to estimate the sound source position that has been difficult for the conventional system using a small number of microphones, so as to improve the conventional estimating accuracy of the sound source position.;SOLUTION: It is made possible to estimate the sound source position by forming a reflection surface RS as a enveloping surface of spheroid using the location of a collection means and the sound source location as the focal points, by generating main reflected waves with the amount of delay corresponding to the sound source location, and by inspecting the amount of delay between the direct wave and the reflected wave so as to acquire the sound source location and to make estimable the location.;COPYRIGHT: (C)2005,JPO&NCIPI
