Reverberation modeling issues highlighted by the first Reverberation Modeling Workshop

Participants at Reverberation Modeling Workshop I presented solutions to posed reverberation problems using a wide variety of methods. The reverberation problems were posed in both two- and three-space dimensions, and included cases with different levels of boundary roughness, different sound speed profiles, and in some cases, range dependence. A number of important reverberation modeling issues became evident when the results of this workshop were considered in detail following the workshop. These include the important role of coherent effects in determining reverberation structure at short ranges, and the important role of boundary reflection loss in affecting the reverberation level at long ranges. A summary of modeling issues highlighted by this workshop will be presented. [Work supported by ONR and PMW-180.]
