有源噪声控制是消除低频噪声的一种很有效的方法。这种技术在世界上普遍受到重视。目前英国、美国、法国、联邦德国、日本等国家都正在进行有源噪声控制技术的研究和应用。近年来在我国也逐步开展了这方面的研究。本文总结了有源噪声控制技术的发展历史;介绍管道和三维空间有源噪声控制技术的概况,为这方面的研究提供一些参考。
Active noise control is a very effective way to eliminate low frequency noise. This technique is generally valued in the world. At present, the United Kingdom, the United States, France, the Federal Republic of Germany, Japan and other countries are under active noise control technology research and application. In recent years in our country has also gradually carried out research in this area. This article summarizes the history of the development of active noise control technology, introduces the general situation of pipelines and three-dimensional active noise control techniques, and provides some references for the research in this field.
