Modeling Near-Shore Acoustics
Abstract
The ultimate aim of this research is to develop an accurate and reliable tool for predicting sound pressure level at shore due to noise sources above or below the sea surface. The improved understanding of the detectability of Naval vessels will preserve and increase the safety of personnel and equipment during stealth maritime operations. Specifically, the PIs have been involved in modeling and measurements of acoustic propagation over distances ranging from hundreds of meters to several kilometers. To date, the effort has focused on the development of a robust mathematical model of acoustic transmission loss given current atmospheric and weather conditions. The primary goal of this project is to incorporate additional factors affecting the near-shore acoustics in the numerical solver developed at Catholic University of America. The proposed research aims to: model sound attenuation of littoral and riverine ground and vegetation like wet sand, coastal shrubs, mangroves and marsh grass; investigate the masking noise generated by the breaking of shoaling waves and how it relates to physical characteristics of the shore; model sound transmission through near-shore water-air interfaces and the detection inair of underwater sources. The PIs# are committed to involve students in meaningful research endeavors to better prepare them for success in graduate study or professional practice in many DoD-related paths. This work will also serve to support development of graduate courses in numerical methods in acoustics.
