Study of Design and Calibration of Moving Sound Source Localization Array

In aircraft flight noise measurement technology, moving sound source localization based on microphone array is the key technology of flight noise measurement. The technology of moving sound source location is mainly related to array design technology and microphone array calibration technology. In this paper, the acoustic sources of different velocity in the acoustic chamber are analyzed,The actual position of noise source is obtained by using the program. Through comparison and analysis,the feasibility of moving sound source location is verified, which lays the foundation for the aircraft flight noise source location.
