The effectiveness of applied means of traffic noise protection can be determined through examining acoustic climate of the areas located near the communication routes. It allows to determine sound level in a specific area and determine the extent that its inhabitants are exposed to the effects of noise. The research and the analysis of the acoustic climate were carried out in the town of Podszosie, located in the vicinity of the S7 expressway. The aim of the research was: to determine the level of noise emitted by traffic on the S7 expressway, to determine the effectiveness of noise barriers installed in a given area, to determine the sound level in the vicinity of properties located in Podszosie, to determine whether the noise level in Podszosie is normal. The conducted research allowed the authors to determine the sound level prevailing in the study area, and to what extent its inhabitants are exposed to the effects of noise and how to prevent it. Showing the scale of the problem posed by noise from road transport. In addition to carrying out activities aimed at reducing its level, society should also be made aware of the harmful effects of its impact.
