The paper presents the results obtained for the noise level measurements in the city of Bacau, Romania. The measurement point was chosen close to the main road of the city, in an inhabited area. During all day the values of the maximum time-weighted sound level shows a significant exceeding of the permissible limits, indicating a serious noise pollution in the area. The IMMI software was used to obtain the representation of noise dispersion in the studied area. The map shows that the neighborhood inhabited areas are affected by street noise, although some of the noise pollution is absorbed by the trees' barrier on the roadside. In order to reduce the noise pollution impact, some solutions are proposed.
