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静音区的关键问题。这将为空间区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。通过该项目开发的新技术预计将为声信号处理研究的未来发展奠定基础，并将有广泛的应用，如减少汽车内的噪音，在客机上创建单独的静音区，以及减轻工业工厂向邻近郊区发出的噪音。这项提议的结果也将具有重要的经济意义，因为它可以减少对在嘈杂环境中工作或生活的人构成的健康风险。

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.
