SUMMRY:
Wide use of tram connections in modern cities, significant sound levels from these sources, the proximity of tram tracks to residential buildings, led to the conduct of this study.
The purpose of the work was to determine the impact of high-speed trams on the acoustic condition of the adjacent household area and to give it a hygienic assessment.
Materials and methods. Measurements were carried out using the Octave 11A noise meter during the period of the most intensive tram traffic in the daytime. The duration of measurements at each point was equal to 2 hours. The average traffic intensity at the time of measurements was equal to 10 trams/hour on one track (6-minute interval). The approximate speed of the trams during movement was 30 km/hour. The distances during the measurements depended on the distance from the rails of the tracks to the fencing of the territory of the high-speed tram.
Results. Based on the results of determining the acoustic characteristics of trams, it was established that the maximum sound level of trams (speed 30 km/h) was equal to 73.178.9 dBA, depending on the section of traffic, the brand of tram and the design of the canvas; the equivalent sound level during the day is in the range of 49.152.0 dBA, in the range of 47.048.8 dBA at night.
Conclusions. Taking into account the obtained results, it can be concluded that a distance of 25 m from the nearest high-speed tram track to residential buildings can be considered as the minimum permissible (in these areas, under existing operating conditions, without taking into account the noise of the traffic flow) when new residential buildings are located near the high-speed tram lines.
