广州天河体育馆建声、电声系统测试分析
Measurement and Analysis of Building Acoustics and Electroacoustic System for Guangzhou Tianhe Gymnasium
【摘要】 结合广州天河体育馆详细介绍了体育馆建声、电声的设计优选指标及测试过程,并针对实测数据进行分析,提出了对建声的修改方案,同时对改造后方案的满场混响时间进行了推算。从推算结果可知,天河体育馆满场按照80%的上座率计算,中频满场混响时间可降至1.8~1.9s,达到规范的优选范围。
【Abstract】 It is introduced briefly in this paper that how to design and measure building acoustics and electroacoustic system of gymnasium. According to the measurement, a revised scheme for building acoustics is proposed and the occupied reverberation time is calculated. The results show that the occupied reverberation time can meet the standard requirement.
