Toward Noise Modelling in Urban Areas

Noise field measurements are the only precise method of estimating environment pollution. They are long-term and expensive and are not applicable in case of prediction of conditions caused by the new intervention in space. Independent of the bases of available data, which are sometimes very limited, and of the choice of calculation method for reliable prediction of environmental conditions, making the calculation model is an important segment. In that process it is necessary to consider specific features of the location as well as of the model of behavior of all elements in the process of noise emergence (vehicle, traffic surface, machines, devices), significantly influenced by socioeconomic and economic conditions in the country. This paper provides the calculation model for the prediction of environmental noise for three relevant locations in business and residential areas of Zagreb (Croatia) and their verification was done with regard to field measurements.
