Abstract
The paper deals with modeling the acoustic transmission through a perforated interface plane separating two
halfspaces occupied by the acoustic medium. We considered the two-scale homogenization limit of the standard
acoustic problem imposed in the layer with the perforated periodic structure embedded inside. The homogenized
transmission conditions govern the interface discontinuity of the acoustic pressure associated with the two halfspaces
and the magnitude of the fictitious transversal acoustic velocity. By numerical examples we illustrate this
novel approach of modeling the acoustic impedance of perforated interfaces.
