摘　　要：本文通过对风机主要噪声源及频谱、噪声特性的分析，提出了风机结构、气动参数对气动噪声的影响．对国内离心、轴流风机噪声控制的一般方法进行了归类总结，并对国外离心、轴流风机噪声控制的研究方向及方法作了简介．本文可供从事风机设计与制造的工作人员作为参考．In this paper, the main noise source and frequency spectrum and noise characteristic are analyzed and the effect of blower structure and pneumatic parameter on pneumatic noise are discussed. Morever,the practical noise control ways now being used in our country over centrifugal and axial-flow blower are sorted,and based on a colllection of the latest information, the study tendenly and mehods are introduced blriefly. This essay can be used as a reference for engineering and technical person who are engaged in mechanical drawing and manufacturing.
