Abstract
A simple first-order shear deformation theory is presented for vibro-acoustic analysis of sound radiating plate by reducing one unknown displacement function. The proposed method is formulated based on the Rayleigh-Ritz method for natural frequency and mode shape analysis and the first Rayleigh integral for sound pressure level (SPL) curve prediction. The numerical solution of SPL curve prediction obtained using this method is compared with that obtained using the other existing theory. The comparison study shows that the simple method can produce results close to those produced by the existing theory. The applications of the proposed method have been illustrated by determining the SPL curves of plates with different thicknesses.
