Verified acoustic propagation predictions for a shelf-break case
Richard B. Evans, David B. King · The Journal of the Acoustical Society of America · 2001
A comparison is made between transmission loss computed with stepwise couple modes and the parabolic equation for several shelf-break cases. The close agreement between these two diverse approximate solutions of the wave equation can be interpreted in one of two ways: Either both are producing the correct result or they are making identical errors. The low probability of the second coincidence is interpreted as verification of both results. The difficulties encountered in obtaining verified propagation results are discussed.
