A method is presented to calculate the sound pressure produced by the structural vibration based on the results of the numerical or experimental vibration analysis of the structure. The vibrating surface is divided into rectangular elements. It is assumed that the finite element analysis gives the displacements and rotations of the node points of each element and the experimental analysis gives the displacements. The interior displacement of an element is expressed by an interpolation function. The sound pressure produced by each element at a point in space is given by integrating a function that includes the interpolation function. The sound pressure produced by the whole structure is calculated by summing up the contribution of each element. The accuracy of the interpolation function is examined. An application of the method to the prediction of the pressure of the sound radiated by an engine block model is presented.
