Abstract:

The long-term goal is to study the physical processes controlling the propagation of high frequency acoustical signals. Of particular interest is the relationship between bubble distributions, surface gravity waves and turbulence and their effects on sound propagation as it affects underwater communication. A second long-term goal is to model these processes to improve our understanding and to enhance the predictive capabilities. Our objectives are 1 to develop new techniques and approaches for high frequency acoustical propagation experiments in environments with dense bubble distributions and significant turbulence 2 to carry out such experiments 3 to model sound propagation in these environments and 4 to interpret the results in terms of appropriate acoustic models.
