Abstract: 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.
