Acoustical holography has been widely applied for noise sources location and sound field measurement. Performance of the\nmicrophones array directly determines the sound source recognition method. Therefore, research is very important to the\nperformance of the microphone array, its array of applications, selection, and how to design instructive. In this paper, based on\nacoustic holography moving sound source identification theory, the optimization method is applied in design of the microphone\narray, we select the main side lobe ratio and the main lobe area as the optimization objective function and then put the optimization\nmethod use in the sound source identification based on holography, and finally we designed this paper to optimize microphone\narray and compare the original array of equally spaced array with optimization results; by analyzing the optimization results and\nobjectives, we get that the array can be achieved which is optimized not only to reduce the microphone but also to change objective\nfunction results, while improving the far-field acoustic holography resolving effect. Validation experiments have showed that the\noptimization method is suitable for high speed trains sound source identification microphone array optimization.
