摘要
提出一种基于传声器阵列的自动声源定位方法.该方法首先用一个传声器阵列获取声源信号,然后用基于互功率谱相位的时延估计方法计算传声器对间信号的时间延迟,最后应用Tabu搜索算法搜索最佳声源位置.计算机模拟结果表明,该方法是一种定位精度高、运算量较小的声源定位方法.
A new method using Tabu search algorithm to find the position of a sound source in a room is proposed. The signals are received by a microphone array with 12 microphones and the source localization algorithm is implemented to treat them in two-steps. The first step determines the time delay of arrival for selected microphones. The time delay are estimated by using crosspower-spectrum phase algorithm. The second step finds the position of the sound source by using Tabu search algorithm. The experiments show that it is an accurate method with less computation.
