摘　　要：湖北省政府多功能厅是省政府举行国办视频会议和全省大型会议的重要场所,由于其原有扩声系统设计不完善且设备老化,迫切需要重新设计。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,需要在建声和电声方面同时下功夫。针对以上问题阐述了多功能厅扩声系统的设计和调试技术,以及最终达到的良好效果。The Multi - Functional Hall of Hubei provincial government is an important venue for state video conference and large conferences by the provincial government. Since the original sound reinforcement system design was not perfect, and the aging equipment, the urgent need for a thorough, detailed and scientifically redesigned is necessary. The new system not only needs to ensure the quality sound reinforcement effect and to provide good sound effects, but also meet the needs of good transmission frequency characteristics, sound field nonunifornity, audio gain, and high performance indicators etc.. It needs to work hard at acoustic and electro-acoustic aspects at the same time. This paper describes design and adjustment technologies of sound reinforcement system which to achieve good effects finally in the Multi - Function Hall.
