Study On Improvement Of Sound Insulation Performance Of Lightweight Building Partitions

At present,China’s construction industry presents an extensive development mode.To build a beautiful China,we must adhere to the harmony between man and nature,among which resource conservation is the top priority for ecological protection.Light partition wall has been widely used due to its advantages of light weight,low resource consumption and high cost performance,and has made an important contribution to low carbon architecture.However,with the continuous improvement of people’s demand for a better life,the problem of insufficient sound insulation performance of light partition wall is becoming increasingly prominent,which has brought serious troubles to people’s life.Therefore,how to improve the sound insulation performance of light partition wall more efficiently has become an urgent problem to be solved.In this paper,the main research direction is the sound insulation of air.Through the analysis of noise types,sound insulation principles and characteristics,combined with the experimental methods and evaluation standards of sound insulation testing,it provides sufficient theoretical basis for the improvement of sound insulation performance of light partition walls.To improve the sound insulation performance of the light weight partition wall,we should first investigate and analyze it,and select the representative light weight partition wall for experimental test,so as to get the sound insulation characteristics of the light weight partition wall itself.Based on theory and data,it is found that the key to improve the sound insulation performance of lightweight partition walls lies in the performance of additional sound insulation structures.Therefore,a comparative study is made on the commonly used additional sound insulation structures to find out the factors of insufficient improvement of sound insulation performance,which points out the research direction for the improvement of sound insulation performance in the following paper.With the continuous development of the field of architectural acoustics,the emergence of materials to improve the sound insulation performance,it is necessary to understand the properties of various acoustic materials,and choose suitable materials for the sound insulation structure.Based on the analysis of the defects of the commonly used additional sound insulation structure,a sound insulation structure with improved sound insulation performance and high efficiency is designed from the aspects of structure thickness,material installation location and selection of air layer thickness through in-depth research.In order to ensure the full utilization of resources and the improvement of construction efficiency,the prefabricated assembly design is carried out.Through the in-depth study of material,structure and construction,a new sound insulation structure adapted to people’s living needs has been designed.Through theoretical calculation and experimental test,it is fully proved that the new sound insulation structure with comprehensive design has good sound insulation performance.Today’s low carbon development overall layout has been incorporated into the ecological civilization construction,more and more buildings will be more low carbon environmental protection of lightweight partition,in order to adapt to the needs of the development of the low carbon buildings attach new sound insulation structure of lightweight partition on low carbon environmental protection experiment test,through the experimental data proved that still has a good sound insulation performance.Finally,based on the sound insulation performance improvement design scheme and the application of low carbon lightweight partition,a general method to improve the sound insulation performance of lightweight partition is summarized,which provides a reference for the sound insulation performance improvement design of lightweight partition and other types of partition in the future,and provides a reference for the relevant standards and specifications.
