This paper aims at attributing classes of urban blocks of a same induced occupation zone for the differentiation of the sound pressure level achieved on the surroundings of these urban blocks. The actual state of noise is described and areas with noise levels above the limits suggested by the Brazilian Standards Regulations are identified. Therefore, the applied method comprehends a delimitation of the study area in an occupation zone of São Carlos (SP). In this area, sound pressure levels are collected in peak hours of vehicular flow, which are used as data entry for an application of a prediction model and noise mapping. The mapped levels are counterexamined with the current regulations for human acoustical comfort and classes of urban blocks are proposed. The results allow highlighting the urban blocks for which control actions should be taken into account, in order to guarantee the local quality of the acoustical environment.
