This paper is concerned with the soundproof characteristics of infinitely long, cylindrical sandwich shells composed of orthotropic face layers and a honeycomb core. The shell is excited by axisymmetric acoustic waves travelling within the shell. To simplify the shell governing equations it is assumed that the facings resist only bending moments and the honeycomb core resists only transverse shear forces. The sound transmission loss for the shell wall, TL, is derived and calculated numerically for various values of the physical parameters involved.
