The analytical solution of a boundary problem, describing the process of penetration of the sound field of a spherical radiator, located inside a thin unclosed spherical shell, through the elastic spherical shell is developed. Influence of some parameters of a problem on the value of the attenuation coefficient (screening) of a sound field inside the spherical shell is numerically investigated.
Keywords: dual series equations for Legendre polynomials, infinite system of linear algebraic equations of the second kind with a completely continuous operator, attenuation coefficient of a sound field.
