Active Sound Control and Noise Cancellation over Space

该项目旨在解决在嘈杂环境中创建声学安静区的关键问题。这将为空间域有源噪声抵消技术的进一步发展提供新的信号处理理论。从该项目开发的新技术预计将支持声学信号处理研究的未来发展，并将有广泛的应用，如降低汽车内的噪音，在客机上建立单独的安静区，减轻工业工厂对邻近郊区的噪音。这项建议的结果也将具有经济重要性，因为它可以减少在嘈杂环境中工作或生活的人所面临的健康风险。

This project aims to address the critical issues for creating acoustic quiet zones in a noisy environment. It will provide novel signal processing theory for further development of active noise cancellation techniques over spatial regions. New technologies developed from this project are expected to underpin the future development of acoustic signal processing research and will have a broad range of applications such as reduction of noise inside cars, creation of individual quiet zones in passenger planes and mitigation of acoustic noise made by industrial plants to neighbouring suburbs. The outcomes from this proposal will also have economic importance as it can reduce the health risk posed to people working or living in noisy environments.
