A rectangular plate is embedded into a flat infinite baffe. The plate's edges are all simply supported. Some effective approximate formulations have been used to determine the values of the self-and mutual-power. The total sound power radiated has been expressed in the form of a series of the selfand mutual-power of the acoustic system discussed. All the theoretical computations have been realized in the case when a part of the plate's area is excited only. All the results presented will further be used for an analysis of the sound power radiated by the enclosure of a power transformer.
