Turbulent flow along a structural boundary acts as a source of noise to the interior space. Characteristics of the transmitted noise are determined not only by the turbulent flow field but also by the transmission characteristics of the bounding structure. In low-speed flow applications, the spatial scale of the turbulence can be smaller than the structural wall thickness. Under this circumstance, thickness effects are important in modeling the wall transmissibility. These effects are examined using the elasticity solution for the axisymmetric response of cylindrical shells. Results are presented for steel-like and rubber-like wall materials and compared with results from thin shell theory.
