In present paper, the interaction of stationary acoustic waves with deformable shallow sandwich panels was formulated on the basis of planar reflection hypothesis to predict pressures caused by reflected and radiated sound waves. Pressures arisen from reflected and radiated sound waves were examined at points on the boundary faces of sandwich panel at the side of incoming waves while pressure arisen from radiated waves were examined on reverse face of the panel. Exact analytical solutions for the prediction of sound insulation parameter presented for simply supported rectangular panels. Numerical solutions were presented for planar square plates.
