| Abstract: | A trijunctional spherical microphone array is designed to sample the sound field.A multiple sound sources localization algorithm is realized by plane-wave decomposition in the three-dimensional spaces with this array.Experimental results show that,using 98-element trijunctional spherical microphone array to locate multiple far-field sound sources can improve the accuracy and spatial resolution of the sound source localization.In addition,this method is robust to the environmental noise. |

| Keywords: | sound source localization plane-wave decomposition trijunctional spherical microphone array |
