| 摘 要： | 运用LabView和Matlab软件实现了基于传声器阵列的声源定位实验,该实验以基于声音到达时间差的定位技术为理论基础。在此基础上,声源的位置在沿着x和y方向上移动,这时四元阵和五元阵的阵列模型都能准确地定位出声源的空间位置,但五元阵的稳定性更强。声源定位技术为实现声源的可视化奠定了基础,同时在军事等领域也有非常重要的应用价值。

| Abstract: | An acoustic source localization experiment based on microphone arrays, which is on the theoretical basis of the time delay estimation positioning technology, is implemented in the paper by using LahView and Matlab. In this experiment the acoustic source is moved along the x and y directions respectively. It is turned out that both four - element acoustic array and five - element acoustic array could accurately realize acoustic source localization, but the result of five - element acous- tic array is much more stable. The positioning technology lays the foundation of acoustic source visualization, while it also has important value in military and other fields. |
