Deterministic Methods of Sound Field Computation

Abstract

The results of a series of carefully planned and executed acoustic-oceanographic measurements in the past several years have clearly demonstrated that the ocean has sufficient stability to permit the prediction of a number of acoustic phenomena by models based upon the deterministic(and in this case time-independent) acoustic wave equation. Given that the acoustic wave equation describes the significant features of propagation, the investigation of a particular phenomenon devolves to the questions of environmental inputs and solution techniques. This pager is concerned primarily with the second question: given a complete, deterministic description of the ocean environment, how does one evaluate : the acoustic field?
