Penetration of the sound field of a spherical radiator through the spherical elastic shell. (Russian. English summary) Zbl 1300.74015
Summary: 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.
