摘　　要：主要通过北京人民广播电台环绕声监听系统设计、原理、环绕声扬声器的调校进行阐述并进行分析,包括录制机房监听系统的组成与各部分的作用,着重介绍了环绕声监听系统的设计与搭建,其中通过对DTS进行介绍与基本原理分析,对杜比环绕声与DTS环绕声进行比较说明北京人民广播电台采用DTS环绕声监听系统的原因。通过对DTS环绕声系统设计的不断完善与严格的施工安装,北京人民广播电台DTS环绕声系统取得了较好的效果,经过专家测试和实际使用,标准听音区域频响平直,节目声像定位清晰、准确,监听效果满足5.1环绕声听音要求,符合ITU-R BS.775-1建议书要求。The paper elaborates on and analyzes the design principle of the RBC＇s surround sound system and tuning of the surround speakers, including an introduction to the composition and function of the monitoring system in the recording studio. A priority is given to the design and construction of the surround sound system in the paper, illustrating factors for RBC to em- ploy the DTS surround sound system through a detailed introduction to the system and comparison with the Dolby surround sys- tem. With the gradually maturing design and stringent installation, the DTS surround sound system of the RBC has achieved good results. It has been tested by experts and proved by operation that the standard listening area has flat frequency response; positioning of programs is clear and accurate ; the monitoring effect meets the requirements of the 5.1 surround sound and is in line with proposals in Recommendation ITU - R BS. 775 - 1.
