消声室内运动声源定位研究 Study of Moving Sound Source Localization Array in Anechoic Room

Abstract

在飞机飞行噪声测量技术中，基于麦克风阵列的运动声源定位技术是飞行噪声测量的核心技术。本文利用对消声室内移测架携带的不同速度的运动声源进行定位分析，利用自研程序处理采集数据获得噪声源实际位置，通过结果对比分析，验证了运动声源定位的可行性，为飞机飞行噪声源定位奠定了基础。 In aircraft flight noise measurement technology, moving sound source localization based on mi-crophone array is the key technology of flight noise measurement. 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.
