摘　　要：内蒙古财信集团多功能厅是财信集团举行视频会议、学术报告和大型会议的重要场所,在集团内占据重要位置,对音视频系统提出了很高要求,因此需要进行大量深入、细致和科学的设计。系统设计后,要确保优质的语言扩声效果,还要能提供良好的演出扩声效果,即要具备良好的传输频率特性、声场不均匀度和传声增益等高性能指标要求。要实现以上高要求的性能指标,需要在建声和电声方面同时下功夫。因此,主要阐述多功能厅扩声系统的设计和调试技术,并取得了良好效果。The multi-functional hall of Inner Mongolia Caixin group is an important place for Caixin group to hold video conference,academic report and large-scale conference.It occupies an important position in the group and puts forward high requirements for audio and video system.Therefore,it needs a lot of in-depth,detailed and scientific design.After the design of the system,it is necessary to ensure high-quality speech reinforcement effect and provide good performance sound reinforcement effect,that is to say,it should have good transmission frequency characteristics,sound field unevenness and sound transmission gain.In order to achieve the above high requirements of performance indicators,it is necessary to make efforts in the aspects of architectural acoustics and electroacoustics at the same time.Therefore,this paper mainly describes the design and debugging technology of the sound reinforcement system of the multi-function hall,and has achieved good results.

关 键 词：传声增益 语言传输指数(STIPA) 传输频率特性 声场不均匀度 混响时间 分辨率
