| 摘 要： | 为了治理振动压路机施工时的噪声污染，对两种型号振动压路机施工时的噪声进行了现场测试，对试验数据进行了统计分析，并与采取隔声屏后的噪声数据进行了对比研究，得出振动压路机施工时噪声随距离变化的衰减规律。结果表明，利用隔声屏降低噪声效果明显，在距噪声源7．5m处就达到了国家噪声限制标准70dB。

| Abstract: | In order to control the noise caused by vibraory roller, the experimental data of noise produced by vibratory roller is presented. It is statistically analyzed and compared with the noise of sound barrier experiment. The spreading rule is deduced from the experimental data. It is found that the sound barrier is in good effect, the noise can be reduced to 70 dB in the distance of 7.5m. 2 tabs, 9 figs, 9 refs. |
