Near-field acoustic holography is one of the most important methods to identify indoor noise sources, and on the basis of describing the principle of near field acoustic holography and verifying the feasibility of this principle, it is used to scan the mass transit train in order to effectively control the vibration and noise of urban rail transit train and improve passenger satisfaction. After analyzing the holographic scanning and experimental results of the inner wall noise source of the urban rail trans...
