摘　　要：在高铁现场监测数据基础上,根据环境监测经验确定了5种常见暴露声级测试的测量时间段,分别计算其暴露声级并对其结果进行分析讨论。研究结果表明:采样起止时间不同对暴露声级监测的影响误差在1 dB之内,并且在暴露声级测试时,建议选择T5对应的时间段,该结论为科学合理地环境监测提供了数据支撑。Based on the high-speed rail monitoring data,5 different testing time be determined according to the environmental monitoring experience and the exposure sound level results be calculated and discussed.The results show that： the deviation caused by different sampling time was about 1 dB as well as T5 was be suggested to adopt in the exposure sound level testing.The conclusion provide data support for the scientific and rational environmental monitoring.
