Simulation Research on the Effect of Distributed Coupling Space on the Sound Quality of Multipurpose Halls
The influence law of coupling space on the sound quality of multifunctional halls by utilizing distributed coupling space design is explored in order to improve the indoor acoustic environment of multifunctional halls.The multifunctional hall of Northeastern University taken as an example,the basic data of the hall are first researched and analyzed.Then the distributed coupling space model is established by Odeon software,and the feasibility is verified by comparing simulation values with the measured data,and the influence of the material,construction and coupling surface area of the coupling space on the acoustic energy attenuation degree and reverberation time is analyzed.Finally,two simulated working conditions are set to optimize the transformation scheme.The main space sound environment optimized,the main space reverberation time is reduced by about 30％,and the speech intelligibility index is improved to a good level.And it is concluded that on the basis of guaranteeing the architectural design style,the distributed coupling space can regulate sound environment of the main space,and the sound quality of the main space can be improved with good effect,which provides a theoretical method and technological support for the design of the multipurpose hall sound environment.
