Background analysis of elevator noise

      With the city of science and technology, social modernization intensifies, the real estate market has been booming, many edifice erected, but the attendant problem of elevator rail noise is highlighted. The vibration and noise produced in the operation of the elevator through the walls of the building, floor to solid transmission way to spread around the room. Lift to work for a long time, low frequency noise pollution in the room of life people's hearing, cardiovascular system and nervous system damage is more obvious, make people confused in mind, bad temper, especially to the unborn child growth fetal dysplasia.

　　In the past two years, there are at least 25 in a single city, Chengdu, the cause of the elevator noise caused by the contradiction between developers and owners of disputes. According to the experience of many years of testing China acoustic detection technology research institute and related to the architectural design unit of communication that appears building elevator noise, mainly because the building housing structure considering the appearance and public area saving and other reasons in the design, developers will lift room main load-bearing walls and the owners of the house the load-bearing walls do public walls or wall steel connection caused by. Lift the noise mainly for low-frequency vibration, the solid vibration of sound transmission. Thus providing a transmission steel connection wall design of the architecture itself for the elevator vibration and noise. If in the design by adding Cuoceng, partition walls or set the staircase separating separation room load-bearing walls and interior wall affected owners can improve or solve the noise problem of elevator. Now many large developers have noticed the noise of elevator brings to the quality of real estate and the owners of residential environment, and made the corresponding noise, but the noise removal problem caused by the quality of the elevator itself, there are still many developers ignore the influence of elevator noise in the architectural design and development of buried hidden noise foreshadowing.
