摘　　要：可调混响技术在大型剧院式多功能演播厅中设计应用在国内尚属先例。本文介绍的圆筒式电动可调吸声体的技术设计综合了声学、建筑、装修、机械及电气等多方面的要求，文中着重阐述了可调吸声体的声学设计、结构设计及传动设计技术，并对可调吸声体的混响室试验结果作了简要的分析。This is the precedent in China that the technique for the design and application of theadjustable reverberation is used in a multifunction, large scale auditorium for dramatic show, live telecast.This article introduces the requirements of the various aspects of acoustics, architecture, decoration,mechanics and electricity. It also describes the acoustical, structural and transmission system of theadjustable sound absorber and the result of the reverberation chamber test is also presellted.
