Research On Sound Quality Optimization Design Of Multifunctional Gymnasium With Stage

Among sports buildings,gymnasiums are one of the most common types,and their functional requirements have gradually changed from special functions to multiple functional requirements.In recent years,with the improvement of people’s cultural level and the rise of the quality of life,people not only consider the sound quality design of buildings such as concert halls and rehearsal halls,but also put forward sound quality requirements for sports buildings.As people’s functional requirements for sports buildings are constantly shifting from competitive activities to cultural and recreational activities,a single game space in the hall is not enough to meet other activities.The multi-functional gymnasium with stage provides people with different space requirements.How to provide good sound quality under different functions has become a common concern of many people.Although some scholars have made relevant discussions on sound quality optimization,there are few researches on sound quality optimization specifically for multi-functional gymnasiums with stages.This paper takes the multi-functional stadium with stage as the research object,and on the basis of summarizing the research results at home and abroad,adopts the literature research method,case analysis method,on-site measurement method and software simulation method to conduct an in-depth study of the sound quality status of the multi-functional stadium with stage The analysis provides methodological support for further proposing related influencing factors and sound quality optimization strategies.How to optimize the sound quality design of a multifunctional gymnasium is a common concern of many people.Some scholars have made relevant discussions on the sound quality optimization of the multifunctional gymnasium.However,there are few researches on the sound quality optimization of a multifunctional gymnasium with a stage.On the basis of summarizing the research results in China and foreign countries,this thesis takes the multifunctional stadium with stage as the research object and adopts the literature research method,project analysis method,on-site measurement method and software simulation method to conduct an in-depth study of the sound quality status of the multi-functional stadium with stage.The analysis provides methodological support for further proposing related influencing factors and sound quality optimization strategies.First,conduct a comprehensive analysis of the concept and specification requirements of multi-functional stadiums with stage,clarify the sound quality evaluation indicators of multifunctional stadiums with stage,and analyze the current sound quality of three representative multi-functional stadiums with stage.The sound quality design requirements,the current sound quality of the stage and the competition space are analyzed,and the results and analysis of the sound quality optimization are summarized from them,and the problems existing in the sound quality effects of the multi-functional stadium with stage are summarized.Then,according to the investigation and study of the sound quality problems in the three multi-functional stadiums with stage,the relevant influencing factors are discussed,and the physical factors(planar form,top form,stage form and section form)and interface factors of the multi-functional stadium with stage are studied.(Top interface,side interface and bottom interface),the sound quality requirements of noise factors.It also introduces the necessity of computer simulation in detail,from the aspects of body shape optimization strategy(planar angle,section angle,stage design),interface optimization strategy(side interface,top interface,bottom interface and interface materials),and noise optimization strategy.The sound quality optimization strategy of the functional gymnasium.Finally,this dissertation simulates and analyzes the effectiveness of the sound quality optimization strategy of the multi-functional stadium with stage based on computer simulation.It proposes specific architectural overview and sound quality design indicators for the Xi’an Air Force Engineering University Gymnasium,Xianyang Xizang Minzu University Gymnasium,and Lanzhou University of Technology.The sound quality optimization measures,and finally the use of computer simulation to improve the sound quality effect in the hall,verify the feasibility of theory and practice,and provide a certain reference for today’s sound quality optimization meter with stage multi-functional gymnasium.
