Abstract

The major influence on sound propagation and attenuation in surface ship wakes arises from the presence of bubbles. The aim of the research behind this paper is to obtain a better understanding of the propagation conditions for sound in surface ship wakes in order to be able to produce realistic sound propagation models for predicting acoustic qualities of wakes. A high resolution, multi-beam sonar, looking upward at a wake produced by a passing surface ship, has provided data characterizing the wake structure in the along-wake, the cross-wake and the depth directions. A simple wake model has been developed from historical data, and this model has been used with a 2D PE code to calculate the loss of acoustic energy in the wake. Understanding the complexity of the wake bubble structure, and its effect on acoustic propagation, remains a challenging research goal.
