摘要
对上海地铁9号线运行于高架段、敞开段和隧道段时的噪声分别进行了测试.从所测数据结果的分析总结中得到对地铁车内噪声影响最大的是轮轨噪声,并测得列车在通过隧道内道岔时的噪声可达95 dB(A),由此提出了车内噪声的治理措施和控制手段.
The noise of Shanghai Metro Line 9 running in the overhead line, opening section and tunnel were tested respectively. The measurement data and result analysis show that the greatest impact on the subway interior noise is the wheel-rail noise and the noise of the train coming through the tunnel switch can be up to 95 dB （A）. Thus relative control measurements of subway interior noise were raised.
