Scattering of sound from a spatially distributed, spherically symmetric source by a sphere

General expressions are derived for the scattering of sound from a spatially distributed, spherically symmetric source by rigid and nonrigid spheres. The incident field is determined using a Hankel transform for spherically symmetric variables. The scattered fields are determined by matching the total pressure and normal velocity at the surface of the sphere. Examples of the total and scattered fields are given for a ball source and a spherically symmetric source with a Gaussian spatial distribution. These solutions are compared with results for a point source.
