Verification of Acoustic Propagation Over Natural and Synthetic Terrain

Abstract

In this paper we review the theoretical basis for the PSTOP3D acoustic propagation code and the recently. added features for acoustic source modeling and propagation over porous surfaces. We then present results from verification efforts for free-field propagation, propagation over porous surfaces, and comparison with experimental data for reflections from a wall, Finally, we review recent efforts to extend the modeling capabilities in the code, as well as continuing modeling efforts.
