Estimation of Noise Hazards in Environmental Monitoring Tools Designe in the Subway

When using public transport, the passenger is exposed to noise. In some areas, this noise exceeds acceptable sanitary standards. The effect of such noise is harmful to the human body. The proposed approach allows assessing the level of hazardous noise exposure in the subway area and establishing a safe period of stay in the area using CAD systems. Also, various methods of collecting input data using stationary sensors and sensors of mobile devices of passengers are considered in the article. Different variants of location of sensors in the metro zone are offered. Describes the processing of input data using the developed software. The corresponding graphs and noise maps are being constructed and the results of the evaluation are estimated.
