摘　　要：针对某指挥大厅音视频系统设计项目,介绍该项目音视频系统设计内容和系统功能。常规指挥大厅在设计过程中往往忽视建筑声学设计,导致建筑装修完成后音频系统无法达到预期效果,不能满足标准规范要求,常常需要再次验证建筑声学指标或者对装修进行拆改,造成大量人力、物力、时间的浪费。为避免这一现象,建议同类型项目一定要重视建筑声学设计。本文针对该指挥中心的建筑声学、音频系统、视频显示系统三个子系统进行了同步设计,针对混响时间(Reverberation Time,RT)和噪声评价曲线指标、音频系统声学特性指标、视频系统显示特性指标等系统关键指标进行了详细剖析,可为同类型系统的设计提供借鉴。Aiming at the audio and video system design project of a command hall, this paper introduces the design content and system functions of the audio and video system of the project. In the design process of the conventional command hall, the architectural acoustic design is often ignored, resulting in the audio system unable to achieve the expected effect and meet the requirements of standards and specifications after the completion of building decoration. It is often necessary to verify the architectural acoustic indicators again or dismantle and modify the decoration, resulting in a waste of a lot of manpower, material resources and time. In order to avoid this phenomenon, it is suggested that similar projects must pay attention to architectural acoustic design. In this paper, the architectural acoustics, audio system and video display system of the command center are designed synchronously, and the key indexes of the system such as Reverberation Time(RT) and noise evaluation curve index, audio system acoustic characteristic index and video system display characteristic index are analyzed in detail, which can provide reference for the design of similar systems.
