In this paper, the principal theories of the moving frame acoustical holography and main processes are presented. To build databases of noise maps of noise sources under moving vehicles, several measurements were taken with EMU vehicles using microphone arrays. Moving frame acoustical holography noise maps were obtained in overlap with each component of the under part of the EMU vehicles. Some results are shown and discussed.
