本文主要论述了大型非演出性公共建筑的特点及室内声环境存在的问题和目前此类建筑室内设计常采用的构造处理方法和材料的选择。在调查研究的基础上,根据混响时间计算,吸声减噪的理论,结合本人的设计实践,提出了大型非演出性公共建筑室内声环境设计的原则、要点、材料选择和构造做法。 This paper mainly discusses the characteristics of large-scale non-performing public buildings and the problems existing in the indoor acoustic environment and the selection of the construction methods and materials commonly used in the interior design of such buildings. Based on the investigation and study, according to the theory of reverberation time, sound absorption and noise reduction, combined with my own design practice, the principles, key points, material selection and construction practices of indoor acoustic environment design for large non-performing public buildings are proposed.
