低频噪声主动控制技术实现实用化,需要同时了解其在声学和电子控制方法上的可实现性。本文在系统的文献检索的基础上,综述了局域空间自适应噪声主动控制技术的发展,内容包括用次级声源控制室外局域噪声、围护结构内的局域空间和室外向室内传播的小范围区域空间噪声主动控制在声学上的限制(原理),以及各种控制策略和算法的应用。本文列出的文献包括了已有的重要研究成果,可为读者进一步了解该领域的研究提供详细的背景材料。
The practical application of active control of low-frequency noise requires knowledge of both its acoustical and electronic controllability. Based on the systematic literature retrieval, this paper summarizes the development of local space adaptive noise active control technology, including the control of outdoor local noise with secondary sound source, the local area within the enclosure and the outdoor transmission to the interior The acoustical limitation (principle) of active control of spatial noise in a small area and the application of various control strategies and algorithms. The articles listed in this article include important research results that have been developed to provide readers with further background information on further research in this area.
