An Equivalent Dealing Method of Reverberant Acoustic Field in Vibro-Acoustic Responses Simulation

How to recover cross power spectral density (PSD) in finite element method to predict vibro-acoustic response was discussed in this paper. Its validity was testified by the reverberant acoustic experiment results of some cabin. Predicted responses without regard to cross PSD are in good agreement with the experiment results, which indicate that the method can be used to predict vibro-acoustic responses and are suitable for engineering applications.
