| 摘 要： | 由于大型车站广播系统的使用要求和声学环境特点等原因,完全参照国家有关语言扩声标准进行声场设计存在一定的困难.这里参考现有国家有关标准,根据车站广播系统使用的特点分析,结合对若干新建车站广播系统声场指标的测试数据,初步提出了铁路车站大空间广播系统的主要声场指标,供有关人员参考和补充.这对完成车站广播系统基本功能、规范其工程设计及验收具有一定的积极意义.

| Abstract: | Due to specific requirements and acoustic environment characteristics of the broadcasting system in large railway stations, it＇ s impractical to completely take the national PA system indexes as reference in design of this type station. In this paper, by referring to the existing relevant national standards and analyzing the functional characteristics of railway station broadcasting system, as well as the sound filed test results of the broadcasting system in several newly built railway stations, the main sound field indexes of the broadcasting system for large railway station are preliminarily proposed to provide practi- cal reference for the related designs. It is vital for the basic function design of railway station broadcasting system and stand- ardization of the project design and acceptance. |
