A new method to solve the sound power sensitivity of plates with displacement degrees of freedom is proposed by using the improved acoustic radiation modes model to deal with acoustic radiation and using FEM vibration model for vibration analysis to trcat the structural vibration .Taking a simply supported plate with displacement degrees of freedom as a simulation example, the simulation results show the validity of the presented method.
