摘要
为实现建筑师与声学设计者在同一平台下的合作,介绍了AutoCAD软件中计算前两次反射的方法.此方法是基于虚声源法,通过利用AutoCAD软件中的Auto LISP语言来实现的.运用此方法,文中得到了一个鞋盒式音乐厅和一个体育馆的反射墙面的覆盖范围及前两次反射声到达时间序列,结果验证了此方法的正确性和有效性.
In order to make it possible for an architect and an acoustical designer working together on the same platform, this paper introduces a method to calculate the first two reflections in AutoCAD. The proposed method is based on the image method, and is implemented by using Auto LISP language of AutoCAD. By using this method, the coverage of reflected walls and the time sequence of the first two reflections in a shoe-box-shaped concert hall and a gymnasium are obtained. The results verify the validity and effectiveness of the proposed method.
