The acoustic eigenfrequencies fnsm in concentric spheroidal-spherical cavities are determined for both Dirichlet and Neumann boundary conditions. Two types of cavities are examined, one with spheroidal outer and spherical inner boundary and inversely for the other. The pressure field is expressed in

Analytical expressions are derived for the acoustic eigenfrequencies and modes in a soft-walled spherical cavity with an eccentric inner acoustically small sphere. A straightforward and very simple approach is employed to obtain a first-order perturbation of the cavity eigenfunctions and the corresp
