Shallow Water Reverberation: Data Analysis/Modeling and S. Korea Experiments

Abstract

Shallow water experiments at 3.5 kHz were conducted in two bay settings, one off the Geoje Island, Republic of Korea, the other in Dabob Bay, Washington state. The goal is to investigate mid-frequency sound uncertainty under different environmental conditions, including wind and current. A key feature of the experiments is that transmission loss and reverberation are measured simultaneously in fixed-fixed arrangement. Contrary to conventional understanding, transmission loss and reverberation level respond to environmental conditions differently. Detailed mechanism behind this is complex and includes the difference of sound energy distribution near the sea surface and bottom.
