A numerical method for analyzing the nonstationary vibrations of radially polarized spherical piezoceramic bodies in an acoustic medium is developed. The electrically excited vibrations of piezoceramic spheres with impedance boundary conditions are analyzed. It is established that the vibrations depend on the ratio of the thickness of the sphere to its radius. The vibrations of a sphere with free outside surface and a sphere immersed in water are compared
