Transmission losses predicted by the parabolic equation model FEPE over a 20‐ to 150‐Hz frequency band are compared with transmission losses predicted by Gaussian beam tracing in range‐independent and downslope environments. Ocean impulse responses, computed with each model, are also compared with experimentally determined responses previously reported. [R. L. Field and J. H. Leclere, J. Acoust. Soc. Am. 93, 2599–2616 (1993)]. As in the earlier paper, environmental inputs to the model are derived from the Ocean Drilling Project (ODP) sites near the experiment location, and impulse response comparisons are made using correlation coefficients.
