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。Three kinds of sound barrier： metal plate, transparant plate and transparant plate with rail surihce 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.
