The Mean Acoustic Field in Layered Media with Rough Interfaces

Abstract

An algorithm is presented for determining the mean acoustic field in a layered medium containing rough interfaces. It is assumed that scattering by the rough interfaces when considered separately and in the absence of sound speed and density variation can be well-approximated. It is also assumed that propagation in layered media with flat interfaces can be well approximated. The present work shows how these results can be combined to yield the mean field in a stack of layers with variable sound speeds and densities which are separated by rough interfaces.
