【摘要】： 当前,全国各地的体育设施建设方兴未艾。中小型综合性体育馆的建设在地方体育设施建设中占有绝对的比重。体育场馆的主要作用是体育比赛、运动员训练和人民群众的日常体育锻炼,同时这些体育馆还承担了其他非体育类的功能,比如在体育馆内举行集会、观看文娱表演,举办展览展示等其他经济文化活动。与一般的厅堂相比,体育馆的容量(容积和容座)大,混响时间长,极易引起各种音质缺陷。同时体育馆可供用于布置吸声结构的面积也极为有限,为满足其多功能的使用需要,建筑声学设计显得尤为重要。本文主要研究大厅有效容积小于80000m3的中小型体育馆,指出这类体育馆的声学设计应该达到合适的响度、混响时间、均匀的声场分布,同时能够抑制噪声干扰、避免声聚焦、颤动回声、无回声等声学问题。还分析了各种吸声材料和吸声构造在体育馆的应用效果,列举了中小型多功能体育关建声设计的若干问题,如混响时间的误差、混响时间设计指标的验收、吸声系数的测定以及建声设计与装修艺术的结合等等。最后结合浙大紫荆港校区多功能体育馆建声设计的实例阐述了中小型多功能体育馆声学设计的具体措施和方法。
[Abstract]:At present, the construction of sports facilities all over the country is in the ascendant.The construction of small and medium-sized comprehensive gymnasium occupies an absolute proportion in the construction of local sports facilities.The main functions of the stadiums are sports competitions, athlete training and the daily physical exercise of the people. These gymnasiums also perform other non-sports functions, such as holding meetings in the gymnasiums and watching cultural and recreational performances.To hold exhibitions and other economic and cultural activities.Compared with the general auditorium, the gymnasium has a large capacity (volume and seat) and long reverberation time, which can easily cause various sound defects.At the same time, the area of the gymnasium can be used to arrange the sound absorption structure is also very limited, in order to meet the needs of its multi-function use, the architectural acoustic design is particularly important.This paper mainly studies the small and medium-sized gymnasium whose effective volume is less than 80000m3, and points out that the acoustic design of this kind of gymnasium should reach the appropriate loudness, reverberation time, uniform sound field distribution, at the same time, it can restrain the noise interference and avoid the sound focusing.Acoustic problems such as quivering echoes, no echoes, etc.The application effect of various kinds of sound absorbing materials and structures in gymnasium is also analyzed, and some problems in the design of multi-function sports closing sound are enumerated, such as the error of reverberation time, the acceptance of design index of reverberation time.The measurement of sound absorption coefficient and the combination of building sound design and decoration art, etc.Finally, the concrete measures and methods of acoustic design of small and medium-sized multi-function gymnasium are expounded with the example of the design of multi-function gymnasium in the Bauhinia Port Campus of Zhejiang University.
