办公楼大会议室扩声系统设计

摘要

As the place of meeting report and training,a large meeting room in office building puts forward the higher demands of language sound reinforcement functions.In order to meet the usage requirements of the large meeting room,this paper used the active controllable acoustic beam columns and reinforcement mode of point acoustic source.The sound field simulation was carried out by the EASE software.The simulation results show that the main acoustic indexes achieve the first grade demand of the sound reinforcement meeting standard.%办公楼大会议室主要作为会议报告及培训的场所，对语言扩声功能提出了很高的要求。为了满足大会议室的使用需求，在设计中选用有源声束可控音柱和点声源扩声方式，并通过EASE声学软件对大会议室进行声场仿真模拟。模拟结果表明，大会议室主要声学特性指标均达到会议类扩声一级指标要求。
