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.
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.
