中小型多功能体育馆建筑声学设计探索——以浙江大学紫金港校区多功能体育馆为例

摘要

该文以浙江大学一个体育馆的建筑声学设计为例,探讨多功能体育馆的声学设计目标以及如何通过吸声材料的用法和构造控制中小型体育馆的混响时间,抑制噪声.具体措施包括空间吸声体的布置方法、声学性能测试与对比;墙面吸声的重点提示以及如何抑制噪声;最后运用电脑软件模拟此设计在会议与比赛两个不同声场环境中的具体效果.从而总结出中小型多功能体育馆吸声结构设计的原则,达成理想的声学环境.%the thesis based on an example of the archtectural acousfics design of a sports studium in Zhejiang University.explores the ultimote goal of the acoustics design of a multi-funtional sports studium and the possibifity of ideal acoustic effect through the use and aroper layout of sound absorbing material to control the reverberation time and diminish unwanted sound.Main methods applied include; layout of the sound absorbing material,test and comparision of sound perfomance,attention to the sound absorbing of the walls control of the unwatned sound,and finally the use of simuiation of such a design in computer to find out how it really functions under different sound environment;during a meeting or a sports game,thus pinpointing the main priciples of architeccural acoustics design of a small to medium sized muti-funtional sprots studium,with the ultimate goal of creating on ideal sound effect.
