摘　　要：目的探究分布式耦合空间对多功能厅堂音质的影响规律,以改善多功能厅室内声环境。方法以东北大学多功能厅为例,先对该厅堂的基础数据进行调研分析;然后利用Odeon软件建立分布式耦合空间模型,并与实测数据对比,验证可行性;分析耦合空间的材料、构造和耦合面面积对声能衰减度和混响时间的影响;最后,设置两种模拟工况来优化改造方案。结果主空间声环境得到优化,主空间混响时间降低约30%,语言传输指数提升至良好水平。结论在保证原建筑设计风格的基础上,利用分布式耦合空间可以调节主空间声环境,主空间音质效果提升良好,为多功能厅声环境设计提供技术支撑。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.
