【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。更多还原

【Abstract】 At present, the construction of sports facilities are booming all over the country, the big part of which is the construction of small to medium sized multi-functional sports centers. The main function of a sports center is to host sports fests, to provide a venue for the training of athletes & the daily sports activities of the public. A sports center at the same time has other non-sportive functions. Culture activities, such as rally, performance & exhibitions etc. are often carried out there. In comparison with a normal meeting hall, a sports center is obviously more spacious and has bigger seat capacity. The disadvantage is that the sound lasts much too long, thus causing sound blemish. Considering the limited space in a sports center for the installation of sound-absorbing material, in order to meet the needs of a multi-functional sports center, more attention should be given to the design of architectural acoustics.This article deals with the sports centers with an area of less than 80000 cu.m.. It provides the accurate data of the loudness of sound, the lasting time of sound & the layout of sound distribution, at the same time giving the solutions to acoustic problems, such as the disturbance of noise, the focus of sound, the vibration of echo & no echo at all, etc. It analyses the actual effects of the use of different kinds of sound-absorbing material & equipments in the construction of sports centers, giving examples of acoustic design problems, such as the sound mixing error, the verification of quota of sound mixing time, the measurement of sound absorbing percentage and the combination of acoustic design & decoration aesthetic, etc. Finally, based on the example of the multi-functional sports center in Zhejiang University, Zijinggang campus, the article set forth the measures & ways regarding the acoustic design for the small to medium sized multi-functional sports centers.更多还原
