| 摘 要： | 分别对金属插板式、通透插板式以及装有轨面吸声板的通透插板式3种声屏障进行了现场测试,结合噪声传递路径分析方法,对测试数据进行了等效A计权声压级(LAeq,T)和三分之一倍频程处理。通过同一声屏障的横向和不同声屏障的纵向分析、比较,得出分析结论,并为今后高速铁路的声屏障设计和选择提供了借鉴和参考。

| Abstract: | Three kinds of sound barrier: metal plate,transparant plate and transparant plate with rail surface acoustic board,were tested respectively.For the status quo,combined with noise transfer path analysis,the test data was processed with the equivalent A-weighted sound pressure(LAeq,T) and one-third octave method.Through analysis and comparison of data,the conclusion was drawn.These performance parameters and conclusions provide reference for high-speed railway noise barrier design and selection in the future. |
