Traffic and industrial noise protection in urban areas - experience from Croatia

One of the main reasons of diminishing quality of living in urban areas is the noise. Higher noise levels are mostly caused by road and rail vehicles traffic and sometime the industrial plants operation. This paper presents the protection of residential areas in Zagreb from traffic and industrial noise. As one example is presented protection from road traffic noise of a primary school in Zagreb, which is located near a city avenue with very high traffic volume. The other example is about protection against the industrial noise, of a residential area located near an asphalt mixing plant. Both locations were protected by the noise barriers. On the first location (Primary School) noise protection barrier was put up in September 2006 and on the second (asphalt mixing plant) in February 2007. In both cases short-term measurements were carried out after the construction of the barriers. One sound level meter was placed in front of the barrier and another at the same time behind the barrier, both close to the protected objects. The results of the measurement on the site were compared with calculated forecasted results from the project and a very good match between the two sets was obtained.
