本文首先讨论建筑中的噪声标准——人们在睡眠、工作和休息时所希望的低声级;然后研究通风管道系统中的噪声源,对过去20—25年关于机械设备系统中噪声控制问题作了述评;最后给出了许多实物图片,说明隔振技术在工程中的最新应用。
This paper begins with a discussion of noise standards in buildings - the low levels of sound people want when they sleep, work, and rest; then studies the sources of noise in ventilation ductwork and reviews the noise control issues in mechanical equipment systems over the past 20-25 years The review; Finally, a lot of physical pictures are given to illustrate the latest application of vibration isolation technology in engineering.
