Update on the reverberation modeling workshops.

In order to investigate the status of reverberation modeling and establish well‐defined benchmark problems, two reverberation modeling workshops have been jointly sponsored by the Office of Naval Research and the Navy Program Executive Office C4I (PMW 120). The first workshop was held 7–9 November 2006, and the second during 13–15 May 2008. This paper presents the approach used in formulating the reverberation problems posed to workshop participants and shows examples of the modeling agreement obtained for some of the workshop problems. Issues that have arisen as workshop participants have collaborated in their attempts to produce consensus solutions will be pointed out. Finally, some of the problems to be addressed at a proposed third workshop will be discussed.
