摘要
本文介绍了某高校礼堂音响扩声系统设计。首先介绍了扩声系统设备选型及音箱布置方案,并对礼堂扩声系统进行声场分析。进行声场分析时首先给出分析依据,利用声场分析软件EASE4构造出建筑3D模型图和礼堂音箱布置内部观测图,生成音箱声向图、音箱3dB覆盖图和声场图。通过分析图给出的计算结果,验证了礼堂音响扩声系统的声学特性已完全达到设计指标参数。
This paper introduces the design of sound expansion system in a college auditorium.Firstly,the equipment selection and speaker layout scheme of the sound expansion system are introduced,and the sound field of the auditorium sound expansion system is analyzed.For the sound field analysis,the analysis basis is given first of all,and the sound field analysis software EASE 4 is used to construct the 3D model map of the building and the internal observation map of the auditorium speaker layout,and generate the sound direction diagram,the 3dB coverage map and the sound field map.Through the calculation results,the acoustic characteristics of the auditorium sound amplification system have fully reached the design parameters.
