It is well known that the vibration induced acoustic pressure in an acoustic fluid can be theoretically calculated by Rayleigh integral techniques. But it needs a lot of calculations since it contains integral form equations. In this study, an alternative calculation method was suggested by using Timoshenko-Mindlin plate theory. The governing equations for circular plate vibration and acoustic pressure were simultaneously constructed. The solutions to the coupled equations can be obtained by the proper coordinate transformations. In order to show the effectiveness of the method, this technique was applied to a clamped layered circular plate with structural damping in contact with an inviscid fluid, and so the nearfield and the farfield pressure in the fluid and radiated power were calculated.
