This paper discusses analytical Statistical Energy Analysis (SEA) applicability to structural-acoustic coupling systems by means of Finite Elemental Method (FEM) calculation. At first, we summarize analytical equations about SEA primary parameters (power input, subsystem's energy, and coupling loss factor). Next, we calculate these parameters by using analytical SEA and FEM calculation in order to verify the equations for these parameters. FEM calculations are performed to compare power input, subsystem energies, and coupling loss factors on structural-acoustic coupling system. The analytical SEA predictions are also compared with FEM calculation results.
