摘要
依据工程实例,介绍会场系统建声装修设计,主要是对混响时间值、混响时间频率特性的控制。论述了低频不上升的混响时间特性,无论对语言场所还是音乐场所都得到极好的评价。本案例实测STIPA均在0.65以上,平均值为0.73,说明达到国家一级标准STIPA=0.60是不难的。提倡具有视频会议功能的会议室应努力做到STIPA≥0.65。
Based on engineering pactice, the building decoration design of venue sound system is introduced, mainly on the control of reverberation time value and reverberation time frequency characteristics. The reverberation time feature of unraised low-frequency is discussed, regardless of language or music venues are places to get excellent reviews. In this case, the measured STIPA are more than 0.65, average value is 0.73, indicating that meeting the national standard STIPA=0.60 is not difficult. It is advocated that a meeting room with video conference function should achieve STIPA≥0.65
