摘　　要：对铁路车站声场设计进行分析,论述合理的建声设计对客运广播系统的重要性,其中混响时间是定量分析建筑声环境的常用指标。通过对Revit进行二次开发,利用BIM模型快速计算房间混响时间值。结合Revit API,介绍在BIM模型中添加信息、过滤元素及提取信息的方法。在此基础上,通过工程实例阐述整体开发流程及实际应用流程,为BIM在声场设计领域的应用提供参考。This paper analyses the sound field design of railway stations,and discusses the importance of a reasonable architecture acoustic design for the passenger broadcasting system,in which reverberation time is a common index for quantitative analysis of the architectural sound environment.Through Revit secondary development,the reverberation time value of the room can be quickly calculated with the BIM model.Based on Revit API,the methods of adding information,filtering elements and extracting information in the BIM model are introduced.On this basis,the overall development process and practical application process are expounded with engineering examples,which provides a reference for the application of BIM in sound field design.
