Acoustic Transmission Loss through Periodic Elastic Structures
In this model, two fluids are separated by a solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a wave transmitted with a loss through the structure. This model investigates the transmission loss through the structure. The effects of incident angle, frequency and dampings are studied. Important features used: Acoustic-structure interaction with arbitrary incident angle, scattered field formulation, the perfectly matched layer (PML), and periodic boundary conditions.Ref: S.
