为了简化使用话筒阵列对空间声源的定位,文中提出了一种简单的三维空间声源定位方法.该方法在直角坐标轴上放置4个麦克风,声源到达麦克风对之间的时间差可以由测量接收信号的互相关函数得到.由到达时间差和一个近似的锥模型可以很容易得到声源相对于3个坐标轴的方位角,从而转换成极坐标系中的方位角和仰角.相比较已有方法:该方法具有简单易行、计算量小的显著优点. In order to simplify the localization of spatial sound sources using microphone array, a simple method for stereo sound source localization is proposed in this paper, which consists of placing four microphones on a Cartesian coordinate axis, and the time difference between sound source arrival and microphone microphones can be measured Received signal cross-correlation function obtained by the arrival time difference and an approximate cone model can be easily obtained with the sound source relative to the three axis azimuth, which converted into the polar coordinates of the azimuth and elevation. Method: This method has the obvious advantages of simple and easy operation and small calculation.
