Traffic is the most prevailing source ofnoise in cities. With the number of vehicles increasing and traffic intensity growing, the awareness ofenvironment pollution issues necessitates a search for noise reduction possibilities. Noise is justly considered as one of the key ecological problems in many cities andresidential areas. Naujasodiiai residential area located by Highway A2 Vilnius—Panevezyswas selected for the investigation. The highest noise level in the daytime, 70-71 dBA, wasrecorded in the measurement locations A2—A3 at a 7.5 m distance from Highway A2Vilnius—Panevezys. Data of the spread of noise level indicates that higher levels of noiseare recorded on the edges of the residential area. The measured level of traffic-generatednoise in the residential area shows that the equivalent noise level limits are exceeded onlywithin 30 m distance from the highway. This is mainly predetermined by the absence ofnoise reduction barriers. The spread of noise is partly subdued in the central part of theresidential area by an embankment, running along the highway, planted with bushes andtrees. The equivalent noise level measured at the height of 4.0 m in the living environmentof NaujasodZiai residential area was around 1-2 dB bigger than at the height of 1.5 m. Themost efficient way of reducing the noise is to install a noise-reduction wall on an embank-ment and to construct industrial-purpose buildings, e. shields, in the industrial zone infront of the residential area as well as to plant the slopes of the embankment. 收起
