A method of vehicle interior noise order analysis was presented to resolve the loud noise problem in a new indigenous vehicle. Sound and vibration properties of the vehicle were tested. The interior noise and vibration acceleration signals at different positions were obtained, and the major sources of noise and vibration were identified. Base on these results, modifications were proposed for different noise sources. The results provide a reference for the optimal design of vehicle motor and transmission system and the internal noise control.
