Prediction of cavity noise with multiple layer composite plate as the back panel induced by the turbulence

Cavity noise in the cube with multiple layer composite plate as the back panel was predicted and analyzed in this paper. The mode solution was used to solve this acoustical problem,the mode strain and stress transmission matrix in the composite plate was built up,this paper chose the Corcos model as the turbulent boundary layer pressures's wavenumber-frequency spectrum.The cavity noise was calculated,the sound pressure level's difference between the theory and experiment was less than 3dB,the method in this paper can be used to predict the cavity noise underwater.
