暴露声级监测方法探讨

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1dB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.
