摘　　要：噪声源诊断是有效地控制噪声的前提和基础．本文分析了相干分析原理及其在噪声源诊断中的精度，研究了窗式空调器的声辐射特性，并针对某ＫＣ－２０型窗式空调器进行了实际的噪声测试、分析与诊断，得出了其主要噪声源的诊断结果，提出了相应的降噪对策。Noise source diagnosis is a prerequisite of noise control. This paper analyses coherence analysis principles and their accuracy in diagnosing noise sources. It also studies the sound radiation properties of the window-type air conditioner. Noise testing, analysis and diagnosis are made on a real KC-20 air conditioner. The results of major noise source diagnosis and the counter-measures are suggested.
