Název v původním jazyce

Homogenized model of vibro-acoustic transmission on multi-plate panels

Popis výsledku v původním jazyce

We consider problems of the acoustic wave propagation through panels consisting of several vibrating periodically perforated plates. The aim is to model the noise transmitted through the acoustic fluid and influenced by geometrical arrangement of pores in the panel. The global acoustic problem described by the Helmholtz equation involves homogenized transmission conditions imposed along a compliant panel which is formed by multiple plates of the Reissner-Mindlin type. For a suitable mutual arrangement of holes in two, or more parallel plates there is a coupling between transverse and surface acoustic waves propagating along the panel.
