    The numerical calculation of natural frequencies of a spherical shell with an acoustical medium is studied in this paper as an approximation of the human skull. The elastic sphere is described by using thin shell theory and, in general, a compressible inviscid fluid, that is considered in the inside of the vibrating shell. The dynamic characteristics such as the natural frequencies and the modes of vibration are analysed as functions of the geometrical and physical parameters of the studied system. The problem of numerical calculations of the multiple natural frequencies of an elastic sphere and the coupling effect of the sphere and compressible fluid are discussed.
