摘要
利用有限元技术对不同形状舞台音乐反射罩所产生的声场及其建筑声学参量进行了数值分析,并与无音乐罩时的声场情况进行了对比。结果表明音乐罩对舞台及观众席的音质改善有明显效果。此方法对音乐罩设计有实际指导意义。
Using finite element method, the sound field and acoustic parameters of different stage musical reflecting covers are analyzed, Cases with and without covers are compared, and the results show that the acoustics of auditorium with musical reflecting cover is improved. The method is helpful to the musical reflecting covers design.
