| Abstract(in English) | It is necessary to estimate a source location and the direction of an arrival sound to remove the problem on health by the noise pollution of the low frequency sound. Because the wavelength of the low frequency sound wave is long, the wavelength to the distance between the observation point and the sound source ratio is comparatively is low in the sound measurements. It is necessary to consider the phase difference between each microphone that composes the microphone array in an estimation problem for the location of the generation sound source by use of the MUSIC algorithm. The each phase of the steering vector is calculated from an approximation technique by the Taylor's expansion. We estimate the arrival direction and the sound location as a function of the position of the reference microphone in selecting the approximation order of the expansion. |
