Measuring the radiated power from a vibrating source using the integration of the active acoustic intensity normal to the structure surface, suffers from computational cost and the memory of the computer can also be a limiting factor. The multipole translation theory can be used with fast algorithm to accelerate the computation of pressure on the surface in the boundary elements method. This can also be used to measure source directivity and the radiated acoustic power.Published
