摘要：

设计一种三线交点球麦克风阵列，利用该阵列进行球面声压采样，实现了基于平面波分解的三维空间远场多声源定位.声源定位对比实验结果表明，采用98元的三线交点球麦克风阵列进行远场多声源定位,可以提高声源定位的精度和空间分辨率，且对环境噪声具有良好的鲁棒性.

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.

Key words: sound source localization; plane-wave decomposition; trijunctional spherical microphone array
