Energy Finite Element Analysis

In this paper, reverberation chamber high-frequency vibration-acoustic problem for an aircraft cabin is investigated with two methods. One is combining energy finite element analysis (EFEA) and energy boundary element analysis (EBEA); another is boundary element method by SYSNOISE. Comparison is performed between these two methods.
