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

Abstract

LONG-TERM GOALS: To develop accurate models for high frequency sound propagation in shallow water sediments. OBJECTIVES: The scientific objectives are to: 1) quantify the relative importance of scattering and frictional losses in the attenuation of sound in sediment, 2) evaluate and improve existing models of sound propagation and, 3) develop more complete models of sound propagation which can account for the complexity of shallow water sediments.
