Transmission loss in the far field over a one-layer seabed assuming the Biot sediment model. (English) Zbl 0882.76089

Summary: A system of differential equations is derived from Biot’s constitutive and motion equations for a poroelastic material, and a model for a one-layer seabed is constructed. A normal mode representation for pressure in the far field is found in the case of constant parameters. The model’s prediction for transmission loss is examined for five different types of sediments and compared to the predictions of a solid elastic half-space model.
