Summary:

Energy Finite Element Method (EFEM) is an alternative method to currently practiced Statistical Energy Analysis (SEA) for the solution of high frequency vibro-acoustic problems. In this paper, the theory of the energy finite element method for interior noise prediction is reviewed first. This is followed by the investigation of two example problems using EFEM; (a) the interior noise of an airplane cabin and (b) the sound transmission loss of a dash. In both case EFEM results are compared to SEA predictions. The EFEM and SEA results using different mesh density are also investigated. Further, the advantages of EFEM in the solution of high frequency vibroacoustic problems are discussed
