Abstract
- It is well known that acoustic propagation in shallow water is greatly influenced by an interaction of reflection, transmission, and scattering with the boundary condition. Especially, acoustic propagation of low frequency is depended on the structures of seabed and sub-botttom layer. In this study, acoustic propagations for low-frequency in shallow water were measured from field experiments under the condition of mega-ripple. The study area formed various mega-ripple caused by strong tidal current. Precisely bathymetry and sub-bottom structure were obtained from multi-beam and sparker system. In the experiments, acoustic source and receiver for propagation measurement were single bulb system and multiple self recording hydrophone system, respectively. From the measurement, we described characteristics of acoustic transmission for low frequency around the mega ripple regions.n the structures of seabed and sub-botttom layer.
