摘要
国家体育场馆建设行业标准已对建筑声学指标做了明确规定,在对南京奥体中心体育馆进行声学设计时,发现现行体育馆声学标准还有值得商榷的地方,特别是对大型或特大型体育馆。结合体育馆的使用功能、建筑结构,分析了体育馆声学设计的特点、目的、方法。指出:体育馆声学设计的概念应该是建筑声学和扩声系统设计的统一体;体育馆不存在传统最佳混响时间的概念,体育馆“最佳混响”就是混响时间和扩声系统结合达到的最佳清晰度概念;现行体育馆建筑声学标准中混响时间可以放宽,其意义在于扩声系统和声学装修的优化结合,从而节约国家相关建设投资。
Through the acoustical design of Nanjing Olympic sports center, it is found that many aspects of the existing code for acoustical design on gymnasiums deserve to be discussed, especially for large and overlarge gymnasiums. Taking account of the performing functions and architectural structures, the characteristics, intentions and methods of the acoustical design for gymnasiums are analysed. It is pointed that the concept of the acoustical design for gymnasiums should be an entity of the architectural acoustics and the designs of sound reinforcement , that the concept of traditional optimal reverberation time in gymnasiums, which is actually the optimal articulation obtained by reverberation time and sound reinforcement, doesn＇t exist, and that the reverberation time in existing code for acoustical on gymnasiums can be widen.
