多功能礼堂的声学改建设计

针对某高校将会议礼堂改建为具有音乐厅、电影院和剧场等多功能类厅堂的需求,通过声学设计软件EASE对原有建筑的声学环境进行建模与模拟,对所得数据进行分析比较,找出原建筑的声学缺陷及扩声系统的不足,并对礼堂装修材质和扬声器系统进行有针对性的调整与更换,使计算机模拟下的各项相关数据达到多用途类厅堂声学特性的国家标准,得到满足会议、报告、电影放映及文娱演出等多功能为一体的理想多功能礼堂的声学改造方案.

Design for acoustic renovation of multi use auditorium

In order to meet the demand of renovating a conference auditorium at a university into a multi use auditorium with such functions as concert hall, cinema and theater, the acoustical environment of original building was modelled and simulated with the acoustic design software EASE. Through comparing and analyzing the obtained data, the acoustic defects in original building and the disadvantages in the sound reinforcement system were found out. In addition, the targeted modification and replacement in both decoration materials and loudspeaker system of auditorium were performed, which could make the various relevant data simulated by computer reach the national standard of acoustic characteristics of multi use auditorium. The acoustic renovation scheme for the ideal multi use auditorium, which can combine such functions as conference, reporting, film screening and cultural entertainment in one building, can be obtained. 
