Computer assisted evaluation of traffic noise level

This article presents the main aspects concerning the traffic noise as well as the elements that generate it. Starting with a study on several street profiles, the paper takes into account the variability of modelling parameters (height of buildings, distance between the faзades of buildings, green zones, composition of traffic etc) and then, analyzes the influence of these factors on the traffic noise level. At the same time, it proposes a comparative study of the equivalent noise level, calculated and measured "in situ", in several boulevards of the Romanian capital city, Bucharest.
