公共广播工程部分声学特性测量报告——《公共广播系统工程技术规范(草案)》验证报告之一

Testing Report of Some Acoustical Specifications for Public Address System and Engineering——One of the Validating Reports for "Technical Code for Public Address System and Engineering"

公共广播系统声学特性指标测量是一项新的尝试,到目前为止还没有相应的国家标准可循。笔者根据《公共广播系统工程技术规范(草案)》的规定,选取了几个公共广播系统的若干个广播服务区进行了实地测量,并结合《公共广播系统工程技术规范(草案)》的规定对几种主要的指标进行了讨论。

The testing of acoustical specifications for public address system is an attempt and there is not corresponding national standards or codes for reference so far. According to the stipulation of ＂technical code for public address system and engineering＂, speaker zones in several public address system engineering and conduct testing on the spot are selected. In this article,several main acoustical specifications combining the stipulation of ＂technical code for public address system and engineering＂ are discussed.
