摘要
低频噪音污染问题受到了人们越来越多的关注。本文对通风、空调系统中的低频噪声及其产生做了详细的介绍;讨论了低频噪声的评价问题,提出用C声级来计量低频噪声的声级;从主观影响和客观影响两方面介绍了低频噪声对人的影响;介绍了有源噪声控制法在通风、空调系统中的应用。
The awareness of low-frequency noise generated by HVAC systems has been a serious and increasing problem. This paper will introduce the low-frequency noise sources in HVAC systems. The effect of low-frequency noise caused by HVAC systems is also included in this paper. C-weighted criteria should be adopted in the estimate of the low-frequency noise. Active noise control is a effective solution to low-frequency noise problems.
