反射板设置位置对教室声学特性影响模拟分析

Simulation analysis on the impacts of reflector location on classroom acoustic propertiy

以150人阶梯教室为例,用声学软件分析了反射板设置于讲台顶部和黑板两侧时的不同声学效果,并从三方面进行了论述,该教室将反射板设置于讲台顶部并将其剖面形式进行改良,可以更好地将声音反射到教室听众区的各部位,取得了良好的效果。

Taking the lecture theatre holding 150 people as an example, this paper analyzes different acoustic effects of reflector located in the top of platform and in both sides of the blackboard with acoustic software, and carries on discussion from three aspects. If the reflector is located on the top of the platform whose profile is improved, it will better reflect the sound to various audience areas in the classroom and can achieve good effect.
