摘要
该文提出一种使用声压幅度比进行声源定位的方法。该方法从接收阵列各拾音器所接收之电压信号的幅度与相应拾音器到待测声源的距离两者之间存在的关系出发 ,给出了以声压幅度比为参量的约束条件的表达式 ,建立了利用这些约束条件进行声源定位的算法。为了验证方法的有效性 ,进行了计算机仿真实验。结果表明本文提出的定位方法简单、快捷 。
A method for sound source localization based on the amplitude ratio of sound pressure is presented in this paper. The relation between the voltage amplitude of a microphone and the distance from the microphone and the corresponding sound source is used to establish a constraint for the purpose of sound source localization between a pair of microphones. A localization algorithm by using the constraints is then given in the paper. The experimental results show that the proposed method is simple and effective.
