摘要
体育场馆扩声系统从设计到调试,首要目的是为实现语言可懂度,其次是音乐丰满度。也就是在客观声场环境下,能实现STIPA平均值及五大指标的招标要求。通过对贵阳体育场的封闭EASE模型后的计算机声学模拟结论,与第三方检测结果做对比分析,针对"有必要制定STIPA空场测点最低下限值"问题展开讨论,希望制定出STIPA相应合理的统计标准。
The primary objective of stadium PA system design and debugging is achieved intelligibility, and next is music richness. Through the contrastive analysis between computer acoustic simulation conclusions after closed EASE model of Guiyang stadium and the third test results, the issues of ＂the need to establish low limits of open field STIPA＂ are discussed in this paper.
