Abstract

Sound propagation from multiple dipole and monopole sources in a system comprising of a horizontally stratified fluid above a horizontally stratified porous elastic solid is modelled using the global matrix method to solve the wave equation. A modified Biot-Stoll model is used for wave propagation in the porous elastic solid. Predictions of sound pressure level in the fluid are compared with other numerical routines to validate the program. Predicted radiation fields due to dipole and monopole sources are compared. Numerical techniques to ensure the accuracy and stability of the solution are described. 1 Introduction The Fourier Transform method in the form of Fast Field Program has been used to solve the problem of wave propagation in range-independent stratified env
