In this study, the effects of noise and vibrations caused by railways on the lives of residents around the railways in districts 17 and 18 of Tehran, the capital of Iran which amounts to about 700,000 people, are investigated. In the first stage the actual level of noise was measured at various points which showed above standard levels. Afterward, the authors developed a questionnaire and the survey was conducted from 376 residents. The findings of this study show that the most important factor for the residents adjacent to the railway line is the need for action by the country's railway authorities to reduce and control the adverse effects of noise and vibration. Also, the analysis of inferential statistics performed by chi-square test shows that the variables of gender and proximity of residence or workplace or both to the railway do not affect any of the railway noise or vibration dissatisfaction. The age variable also has no effect on noise dissatisfaction but does impact on vibration. Finally, distance from the railway affects both disaffection from noise and vibration.
在本研究中，对伊朗首都德黑兰第17区和第18区铁路沿线约70万居民生活造成影响的铁路噪声和振动进行了调查。在第一阶段，在各个点测量了实际噪声水平，结果显示高于标准水平。随后，作者编制了一份问卷，并对376名居民进行了调查。本研究结果表明，对于铁路沿线居民来说，最重要的因素是国家铁路当局需要采取行动，以减少和控制噪声和振动的不利影响。此外，通过卡方检验进行的推断统计分析表明，性别以及居住或工作场所与铁路的接近程度这两个变量，对铁路噪声或振动不满情绪均无影响。年龄变量对噪声不满情绪也没有影响，但对振动有影响。最后，与铁路的距离对噪声和振动的不满情绪均有影响。
