Traffic noise (car, rail and air transport) has an influence on human health and the comfort of human life. The human body experiences the harmful effect of traffic noise beginning at values slightly higher than hearing range. This effect involves excessive tiredness, drowsiness and discomfort. Equilibrium, psychomotor fitness and physiological functions may also be disturbed. Acoustic pressure higher than 140 dB causes permanent harmful changes in the human body. This study evaluated traffic noise pollution at three selected sites in Krakow. At the research sites, two sources of traffic noise were present: car and rail transport (trams). The sites were located in the city centre and in the outskirts of the city. The level of traffic noise was measured at three sites in Krakow (research site A: Teligi Street, research site B: Nowy Bieżanów tram balloon loop and research site C: Piłsudski Bridge) on different days of the week (Wednesday and Sunday) and during different times of the day (morning, afternoon and evening). The obtained results show that the level of traffic noise was the highest on the Piłsudski Bridge (research site C), where most of the values exceeded the permissible norms. The two remaining research sites (A: Teligi Street and B: Nowy Bieżanów tram balloon loop) shared similar levels of traffic noise which did not exceed the norm. A comparison of the level of traffic noise at the three research sites according to the day of the week and time of day showed that the level of noise was the highest on weekdays in the morning. During the weekend, the level of noise in the afternoon hours was higher than the value registered in the morning and evening hours. The lowest level of noise was registered at Teligi Street during the weekend in the evening hours, and the highest value was registered on the Piłsudski Bridge on weekdays in the morning hours.

The aim of the study is to analyse and compare the vehicle noise level when driving through the speed bumps and near them. Sound level measurements were taken in selected street cross-sections in Kielce, which are equipped with different types of traffic calming measures. The traffic noise was recorded in one seconds time interval using a manual sound meter. At the same time traffic movement characteristics were being controlled. The vehicle type, driving techniques and the running speed influence elimination allowed to assess the impact of the traffic calming barriers presence and their slowing effect on registered noise values.
