摘　　要：汽车通过噪声具有频带范围宽、随车速变化快、来源众多、产生机理复杂等特点。基于麦克风阵列的波束形成和声全息方法及基于“源-路径-响应”的传递路径分析方法适合于汽车通过噪声这类非稳态工况的噪声源识别。文章概述三种方法在汽车通过噪声识别领域的发展历程及应用情况,分析其特点,最后展望其发展方向,为高效准确识别汽车通过噪声源提供参考。Vehicle pass-by noise has the characteristics of wide frequency band,varying with speed,numerous sources and complex mechanism.The beam forming and acoustic holography method based on microphone array and the transfer path analysis method based on"source-path-response"are suitable for the identification of noise sources in unsteady conditions such as vehicle pass-by noise.The development and application of the three methods are summarized in the field of the vehicle pass-by noise.Their characteristics are analyzed respectively.Finally,the development direction of the vehicle pass-by noise sources identification are expected,which provides a reference for the effective and accurate identification of vehicle pass-by noise sources.
