Abstract : In order to predict the interior noise of the cavity, the basic principle of energy finite element method (EFEM) was introduced. A coupled cavity-plate-cavity energy finite element analysis (EFEA) model was built, and its interior noise was computed with numerical method. Meanwhile, a statistical energy analysis (SEA) model of cavity-plate-cavity was also built. The prediction result of the EFEA model was compared with the result of the SEA model. The result showed that they were in accordance with each other. Moreover, an EFEA model and a SEA model of cavity-front windshield-cavity were built
