摘要
针对超大型铁路站房高架候车厅容积巨大、混响时间长、声场不均匀度大等特点,传统的经验式扬声器布置方法已难以满足高速铁路客运广播对语言清晰度、声压级及声场均匀度的多重需求。本文以超大型站房杭州西站高架候车厅为研究对象,采用ODEON/EASE联合仿真平台,建立几何-材料-声源一体化模型;以混响时间RT、声压级SPL、声场不均匀度ΔL、C7、C50、Alcons、STI七项指标为评价依据,对两种典型扬声器布置方案进行比选。最终推荐候车室采用“线阵列主扩+补声”的技术路线,为超大型站房客运广播工程化实施提供了参考依据。
In response to the challenges posed by the vast volume,long reverberation time,and significant sound field nonuniformity in the elevated waiting halls of super-large railway station buildings,traditional empirical speaker layout methods can no longer meet the multifaceted requirements of high-speed rail passenger broadcasting for speech intelligibility,sound pressure level,and sound field uniformity.This study takes the elevated waiting hall of Hangzhou West Station—a super-large station building—as the research subject.Utilizing the ODEON/EASE joint simulation platform,a geometric-material-sound source integrated model was established.Based on seven evaluation criteria—reverberation time(RT),sound pressure level(SPL),sound field non-uniformity(ΔL),C7,C50,Alcons,and STI—two typical speaker layout schemes were comparatively analyzed.The final recommendation is to adopt the"Mainly line array speakers with supplementary speakers"technical approach for the waiting hall,providing a reference for the engineering implementation of passenger broadcasting in super-large station buildings.
