摘要
结合人流密度的变化对线侧式高铁站候车厅噪声环境进行了现场实测,分析了候车厅声学环境的特点;结合实测的背景噪声数据,采用声学计算仿真软件ODEON模拟了现状情况下的混响时间(RT30)及公共广播系统开启时的语言传输指数(STI)。针对现存问题,提出了不同方案用以提升现有候车厅声学环境,并通过模拟验证了其优化效果。
Based on the flow density changes of the waiting hall in a line-side high-speed railway station,an on-site measurement of noise environment is carried out.The characteristics of the acoustic environment are discussed in this study.Furthermore,combining the measured data of the background noise,acoustic computer simulation program ODEON is used to calculate the reverberation time(RT_(30)) and speech transmission index(STI) of public broadcasting system.Against the existing problems,various scenarios for upgrading the acoustic environment of the waiting room are presented and proved to be efficient.
