有源消声的成功和发展持续不断地激发着人们的研究热情,使其成为噪声控制领域非常活跃的一个方面。八十年代中期以来,随着有源消声研究的深入和高速信号处理芯片的问世,有源消声逐渐朝着三维空间尤其是封闭空间,自适应消声方向发展。本文系统总结了近几年有源消声所取得的成就。指出了一些最主要的最新研究动态,就今后一段时期有源消声的发展方向提出了看法,并指出了一些需要解决的问题。
The success and development of active noise cancellation continue to inspire people’s enthusiasm for research, making it a very active aspect of noise control. Since the mid-eighties, with the deepening of active muffler research and the advent of high-speed signal processing chips, active mufflers gradually evolve towards three-dimensional space, especially enclosed space, in the direction of adaptive noise reduction. This article systematically summarizes the achievements of active noise reduction in recent years. Pointed out some of the most important recent research developments, put forward some suggestions on the development direction of active noise reduction in the coming period, and pointed out some problems to be solved.
