摘要
介绍了扩声系统调整的概要与扩声系统声学测试方法的要点,主要从扩声系统组成、各部件调整要点、遵循的原则,扩声系统声学测试技术所遵从的标准、方法、数据处理方法等方面进行了介绍,鉴于目前一些从业人士对扩声系统声学测试技术了解不甚全面,依据GB/T 4959—2011厅堂扩声测量方法,详细介绍了各种测量内容的具体方法与数据处理,并给出了相关的电子表格(Execl)数据处理计算表。
Summary of PA system adjustment and main points of PA system acoustic testing method are introdnced mainly from composition of PA system, adjustment points, principles, standard, method, data processing of PA system acoustic testing technology. Currently numbers of practitioners have less comprehensive understamting of PA system acoustic testing technology, according to GB/T 4959--2011 hall PA measurement method, specific methods and data processing of various measurements are introduced, relevant spreadsheets（Excel） data processing calculation table is given.
