作者考虑到广大工程技术人员面临日益增多的噪声控制问题而又缺乏这方面的基本知识和适当资料来处理这些问题,在编著时汇集了许多有关噪声,控制的常用原理和参考资料,目的是将噪声控制文献中的大量资料编成简明而紧凑的参考手册.本书主要内容包活:噪声概述,单室和双室不同声学场合的噪声级估算,单层墙、及、双层墙和管道的透射损失,声屏障、隔声罩、局部隔声罩、机罩等设计,噪声问题的分析和建议,风机、泵、电动机、齿轮、 Considering that the majority of engineers and technicians face increasing noise control problems and lack of basic knowledge and proper information in this area to deal with these problems, the author compiled many commonly used principles and reference materials on noise and control in order to compile Lots of information in the noise control literature is compiled into concise and compact reference manuals. The main contents of this book include: noise overview, noise level estimation for different acoustics occasions in single and double rooms, single wall, double wall and pipe Of the transmission loss, sound barrier, noise enclosures, local noise enclosures, hood design, noise analysis and recommendations, fans, pumps, motors, gears,
