建筑声学仿真软件ODEON在混响室设计中的应用

Application of Architectural Acoustic Simulation Software ODEON in Reverberation Room Design

随着建筑声学仿真软件的普遍应用和算法越来越成熟,可直观判断出声场存在的问题,对建筑体型设计给出指导,使早期反射声在时间和空间上能够合理分布,并防止建筑声场出现声聚焦、颤动回声、驻波和声影等声学缺陷,鉴于此本文在混响室的设计中,引进由丹麦科技大学研究开发的建筑声学仿真软件ODEON,进行体型校核、声压级和混响时间T30的模拟仿真计算,从而保证混响室的体型、声场均匀度和混响时间达到设计标准。

With the development of application and algorithm of building acoustic simulation software,it becomes more and more mature and can intuitively judge the existing problems of sound field and give guidance to the architectural shape design,which makes the early reflections in time and space distribute reasonably,and prevent building from acoustic defects such as acoustic focusing,flutter echo,standing wave and sound shadow.In view of the design of the reverberation chamber presented in this paper,we introduce an architectural acoustics simulation software ODEON developed by Danish University of Science and Technology,and the three-dimensional space and modeling correction,sound pressure level,and reverberation time T30 simulation calculation are conducted,so as to ensure the size of reverberation chamber,the sound field uniformity and reverberation time can meet the design standards.
