The characteristic of vibration and noise of an automobile has become an important guide line to evaluate an automobile during the development of manufacturing and comfort of automobiles. In this study, finite element modal analysis was used to extract the acoustic resonant frequency and acoustic modal modes. The results show that the influence of vehicle seats on the acoustic modality should be considered in the acoustic design of vehicle interior cavum. Higher acoustic pressure areas for lower acoustic modalities mainly lie at the anterior/posterior ends or middle of the vehicle interior cavum.
