Underwater noise radiated from marine vessels is a significant problem for research, fishing and military vessels, and is a major source of pollution in the marine environment. The major source contributing to underwater noise is due to the propeller. This work will develop numerical models with experimental validation that can accurately predict the sources of noise generated by marine propellers and acoustic signatures of marine vessels due to propeller motion. This work has great significance for Australia’s construction and military maritime industries. The technologies developed in this project are also applicable to rotors in other industries such as in aircraft, helicopters and wind turbines.

海洋船舶辐射的水下噪声是研究、渔业和军用船舶的重要问题，也是海洋环境的主要污染源。水下噪声的主要来源是螺旋桨。这项工作将开发经过实验验证的数值模型，可以准确预测船用螺旋桨产生的噪音来源以及螺旋桨运动引起的船舶声学特征。这项工作对澳大利亚的建筑和军事海事工业具有重要意义。该项目开发的技术也适用于其他行业的转子，如飞机，直升机和风力涡轮机。
