The SEA (Statistical Energy Analysis) model of the hypersonic aircraft is established based on the SEA theory. Three parameters of the SEA model are determined by the theory, experiential formula and experimental data. Compared the simulation with the experiment, the results of numerical simulation and experiments are basically equal in high frequency domain, but there are much differences in low-frequency. The response sound pressure in aircraft cabin between simulation and experiment is consistent with each other well in both low and high frequency. The errors between them are less than 3 dB. It shows that the method of statistical energy analysis is reliable in the prediction of vibration and noise environment.
