The present paper describes the numerical analysis of the radiated sound field generated by vibration of laminated flat elastic plates in a small enclosure with rigid wall. We try to apply a numerical simulation technique using the finite difference time domain (FDTD)method to the coupled analysis of the vibroacoustic characteristics. The update equations for the FDTD simulation in the sound field and in the elastic body modeled by the isotropy material are coupled at the boundary of both the mediums. Numerical results show that frequency response changes depend on the opening shape and vibration characteristics of stiffer plate. Since the experimental results show the same tendency as the numerical results, the validity of the numerical simulation using the FDTD method in this paper is confirmed.
