摘要
从空调系统噪声源控制入手,讨论各部件噪声的主要控制方法。在此基础上,根据典型的风道结构,详细阐述风道设计中行之有效的降噪方案,提出在传播路径降低噪声的措施。同时对目前城铁客车广泛采用的几种风道吸声辅材的降噪效果进行比较和分析,提出可行性建议和未来的研究方向。
Starting from the noise source control of air-conditioning system,the article discusses the main control methods of noises in each component. Based on this and according to the typical air duct structure,it specifies the effective noise reduction scheme in the air duct design,proposing to reduce noises in the travel path. In the meantime,by comparing and analyzing the noise reduction effects of several air duct sound-absorbing materials that are widely used in urban railway passenger trains,it puts forward some feasible suggestions and the research direction of future technologies.
