摘　　要：在实际音响扩声工程中所遇到最多的两个系统分别是公共广播系统和厅堂(场馆)扩声系统。而且,在很多工程中,这两个系统是集成在同一个工程包内的。因此,对于做扩声工程的人来说,熟知这两类系统用途的差异以及由于用途差异而决定的特性指标和其测量方法的差异是非常重要的。论述了两类扩声系统中主要电声特性指标的差异,说明了指标的测量方法。In the actual sound amplifying engineering encountered in most of the two systems are the public broadcast sys- tem and halls （or venues） sound amplifying system respectively. Moreover, in many projects, these two systems are integrat- ed in the same engineering package. Therefore, for the sound amplifying engineers, it is very important to know the differ- ences about characteristic indices and methods between these two types of system. The differences between the main electroa- coustic characteristic indexes of two types of sound reinforcement system are discussed, and the measurement index is illus- trated.
