    Modelling of the vibro-acoustic transmission on multi-plate perforated panels using two-scale homogenization

  • Original language description

    We consider problems of the acoustic wave propagation through panels consisting of several vibrating periodically perforated Reissner-Mindlin plates. The proposed model of the wave transmission through a layer involving the acoustic fluid and the panel is derived using the homogenization method. This provides homogenized transmission conditions which are prescribed on a flat interface representing the panel, so that the computational complexity of the vibroacoustic problem is reduced, although the geometrical arrangement of pores in the panel is respected in a detail. 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.
