An acoustic classification system in which echoes from sediment-sediment or water-sediment interfaces are compared to model waveforms predicted by Biots equations for a given set of acoustic material parameters. The selection of parameters are varied until it match occurs, indicating the correct parameters of the reflecting sediments. Preferably by formal search algorithms, such as simulated annealing or genetic algorithms, to increase computational efficiency.
