Research On The Sound Insulation Of Common Walls And Exterior Windows Of Residential Buildings In Chengdu,Sichuan

With the development of urbanization and the progress of human society,people not only pay attention to physical comfort,but also gradually pay attention to psychological comfort,building and living environment is becoming more and more developed,the study of architecture has not only stayed in a strong,beautiful,applicable range,the building indoor sound environment has also received due attention.Residential buildings almost carry our time to replenish energy,have a good indoor sound environment,can help people have a good mood,provide work efficiency,enhance life happiness.Now with the development of building materials,more and more people begin to use light walls and add windows to the air layer.However,the light weight of light partition wall is not paid with the law of quality,which makes the indoor sound environment affected.How to improve the sound insulation of light partition wall and improve the living sound environment has become an urgent problem to be solved.This paper mainly studies from the following aspects:1.First of all,this paper reviews the literature,combs the main points of building sound insulation and indoor sound environment,and the methods of field test and laboratory test of building enclosure structure members.2.Through the form of questionnaire survey,we understand the components of exterior wall,light partition wall and outer window commonly used in residential buildings in Sichuan area,and through the field test of the sound insulation of light partition wall and outer window,we know that most of the partition walls can not meet the requirements of indoor sound environment.The response and measures of the head of household to the adverse sound environment are inquired,and the reasons why the sound insulation of the light partition wall can not be satisfied are put forward,and the sound insulation performance of the existing building components is classified.3.The sound insulation of light partition wall and outer window is used to understand the gap between the measured data and the actual use in the laboratory,which lays a foundation for the optimization strategy.4.Find the weak link of sound insulation through data analysis,and carry on the optimization simulation of different working conditions of light wall,put forward the structure optimization design of light wall board.5.The optimization method of outer window is calculated and studied under different working conditions and tested in laboratory,the method of outer window optimization is obtained.
