This project aims to understand how to control noise created by the interaction of airfoils with complex, real-world turbulence. This project is significant because it will develop novel serrated and porous leading edges tailored for complex turbulence for the first time. Using innovative experimental and theoretical techniques, the project will dramatically advance the science of aeroacoustics. The expected outcomes of the project will be substantial reductions in noise from aircraft, wind turbines, submarines and drones. This will provide significant benefits such as a reduction in environmental noise pollution, better public health and submarines with increased stealth.

该项目旨在了解如何控制机翼与复杂的真实湍流相互作用产生的噪音。该项目意义重大，因为它将首次开发出适用于复杂湍流的新型锯齿状和多孔前缘。利用创新的实验和理论技术，该项目将大大推进航空声学科学。该项目的预期成果将是大幅减少飞机、风力涡轮机、潜艇和无人机的噪音。这将带来显著的好处，例如减少环境噪音污染，改善公共卫生和增加隐形潜艇。
