摘要
精选具有代表意义的车站,对该站候车区的本底噪声、语音清晰度和混响时间等参数进行不同点位测试,通过对测试数据的分析,阐述目前高铁车站声场设计中存在的一些问题和不足,并对车站建筑结构、建筑材料、装修材料以及平面布局等因素对广播声场产生的影响进行研究,拟找出既能适应我们新型高铁站房建筑特点,又能充分体现声学结构设计的广播系统设计方案。
Taking a representative station as an example, the paper gives testing data of the background noise, speech articulation, reverberation time and other relevant parameters in different locations of the station, explains the existing problem and insufficiency of the design of sound field in high-speed rail stations through the analysis of testing data, and sets forth the building structure, building materials, decoration materials and plane layout affected on the public address system of the station, in order to fi nd out the design scheme of not only adapting to construction characteristics of new high-speed station rooms but also fully representing the public address system according to the acoustics structure design.
