| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we investigate a method for estimation of environmental sound sources localization based on MUSIC method by small-sized microphone arrays.MUSIC spectrum depends on the property of an array manifold vector provided from a microphone array.By considering the relation between microphone array and MUSIC spectrum, we examine the arrangement of microphones for high accurate localization with fewer number of elements.In addition, we consider sound source dependence of estimation accuracy using environmental sound sources which have various frequency properties.And the sound source positions are estimated by intersections of the estimated directions, which are obtained by a pair of microphone arrays. In the numerical simulation, using microphone array of irregular interspace, localization accuracy can be improved with reduced aliasing. | |
