✦ Synopsis

Sound transmission through viscoelastic sandwich panels into rectangular enclosures is investigated in the low frequency range (0-1000Hz). Both harmonic and stationary random external pressure fields are considered. Two opposite edges of the plate are simply supported while the other two edges are elastically supported. A forced damped normal mode analysis is used for response calculations. Numerical results are presented for different parameters of the viscoelastic core.

Current research has focused on the reduction of sound transmission through the aircraft fuselage into the interior of aircraft due to turbulent boundary layer excitation. The present work utilizes an analytical model, previously developed by the authors, as a design tool in the development of feedb
