Comparison of sound transmission loss and noise reduction for a single-layer hollow cylinder subjected to an oblique plane wave between the present study and (a) Magniez et al.74, (b) Sastry and Munjal73; and (c) and (d) comparison of sound transmission loss for a double-walled shell between the present work and both the theoretical and experimental models presented by Lee and Kim69.
