Introduction: The problem of noise pollution is the most severe problem that most people encounter with in public. The purpose of this study was to investigate the amount of noise pollution caused by Tehran metro train traffic at the time of arrival and departure at the underground stations of Darvazeh Doulat and Tajrish.Material and methods: This study was conducted in the summer and autumn of 1398 in Darvazeh Doulat and Tajrish stations of Tehran Metro Line 1. The maximum and minimum values of noise pollution Intensity were recorded at specific distances from the edge of the platforms in the morning and evenings. Once every three days, 48 stations were measured and analyzed. In the continuation of the research in Tajrish Station, the distribution of noise pollution has been estimated by performing limited impressions using artificial neural network.Results and discussion: The values measured at specific distances from the edge of the platform show that the amount of noise pollution from the arrival of trains to the platform, the simultaneous entry of two trains to the platform, the arrival of non-stop trains, and crossing the platform in most times, was higher than standard. In some harvesting stations, it reached over 100 decibels, which indicates the critical situation of noise pollution in these subway platforms.Conclusion: The methods used in the present study have effectively estimated the amount of noise pollution in subway platforms. By identifying critical areas and providing measures to manage noise pollution, the damage on the health of citizens caused by noise pollution can be managed.
