摘要
通过对不同类型厂房的工作背景噪声值进行分析及实地测量,取得其噪声值数据,汇总分析平均噪声值,根据基础数据模拟广播计算,形成特定背景噪声值下广播系统设计的扬声器选型和应用原则。
Through analyzing the noise values of different types of workshops and field measurement, the background noise values were obtained, the average noise value was summarized, broadcasting calculation was simulated based on basic data, speaker selection and application principles for the design of broadcast systems under the background noise are formed.
