Laboratory Investigations and Numerical Modeling of Loss Mechanisms in Sound Propagation In Sandy Sediments

Abstract

The scientific objectives are to: 1) quantify the relative importance of scattering and frictional losses in the attenuation of sound in the sediment, 2) evaluate and improve existing models of sound propagation and, 3) develop more complete models of sound propagation that can account for the complexity of shallow water sediments.
