USING UPDATED PARABOLIC EQUATIONS CODES TO EXAMINE ACOUSTIC TRANSMISSION LOSSES MEASUREMENTS OVER THE ARGENTINEAN CONTINENTAL SLOPE
Up and down slope acoustic propagation measurements were conducted in 1989 [Milou et al., 1990] over the Argentinean continental slope leading to experimental values of Transmission Losses (TL) for the 100 - 400 Hz frequency band. This enabled comparisons between the obtained data and the parabolic...

| Sumario: | Up and down slope acoustic propagation measurements were conducted in 1989 [Milou et al., 1990] over the Argentinean continental slope leading to experimental values of Transmission Losses (TL) for the 100 - 400 Hz frequency band. This enabled comparisons between the obtained data and the parabolic equation (PE) model predictions. With the aim of examining the effects of using updated PE codes [Collins, 1993] including their corresponding physical and computational improvements, on the already obtained results, predicted TL values are recomputed. An analysis of these new comparisons are presented here |
