Acoustic Transmission Loss Through Multilayer Periodic Elastic Structures

Application ID: 26841


In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. The effects of incident angle, frequency, and damping is studied. The uses the Periodic Port condition to treat the incident, reflected, and transmitted waves.

This model example illustrates applications of this type that would nominally be built using the following products:
