Analytical studies on the vibration and sound radiation characteristics of an asym-
metric laminated rectangular plate are carried out in this paper. Theoretical formulations, in
which the effects of thermal environments are taken into account, are derived for the vibration
and sound radiation based on both first-order shear deformation plate theory and Rayleigh inte-
gral. It is found that the natural frequencies, the resonant amplitudes of vibration response and
the sound pressure level decrease with the temperature rising. The natural frequencies of asym-
metric plates are smaller than those of symmetric plates and the velocity responses of asymmetric
plates are larger than those of symmetric plates.
