摘要
对北京地铁4号线大兴线地铁车辆车内噪声进行了全程实时监测,并对监测结果进行了统计分析。分析结果表明:轮轨噪声是影响地铁车辆车内噪声的主要因素,地铁运行速度、转弯路段对车内噪声等效声级影响明显。
The real-time monitoring of interior noise in Daxing line of Beijing subway line 4 is carried out in the whole course,and the statistics and analysis of monitoring results are conducted.The analysis results show that wheel-rail noise is the main factor affecting interior noise in subway vehicle,and the effect of operating speed of subway,turning section on equivalent sound level of interior noise is significant.
