中文摘要：

有源噪声控制近年来的研究主要集中在低频声的辐射、传播和传入控制方面,在散射声有源控制方面的研究相对不多。本项目以房间内低频噪声控制、厅堂低频音质控制和水下结构低频声隐形为应用背景，研究三维空间散射声的有源控制。由于散射问题及其控制系统实现的复杂性，散射声有源控制的研究目前仅在一维系统中取得一些结果，而实际应用大多是三维的。为在三维空间散射声有源控制方面取得进展，需要在散射控制机理、散射控制策略、控制系统结构、宽带自适应控制算法以及整个物理电子系统的优化上加深了解和有所突破，这些就是本项目拟研究的内容。本项目以实验研究和系统实现为重点，探讨和解决三维空间散射声有源控制实现时可能遇到的问题，力争使本项目的研究结果形成一项国民经济和国防建设中迫切需要的高新技术。
