Abstract
The present work evaluates noise conditions to which people are subject in the central region of São Paulo city. Strategic points were chosen for sound assessment, considering quantitative and qualitative aspects. Different occupancy profiles, height of buildings, constructive density, number of empty spaces, width of the roads and capacity of vehicle flow, were selected. In addition to acoustic measurements, an evaluation of the profile and flow of the vehicles has been made, to serve as input for simulation in a computational model of urban environmental noise and noise mapping of selected areas. The concept of soundscape was approached with the characterization of local sound sources and their sound perception. Questionnaires were applied for subjective assessment and the profile of the interviewees was also characterized. This attitude is important because it leads to an understanding of who exactly is exposed and affected by certain sound levels, and how the same sound level can generate different perceptions. This sensibility while approaching the subject makes people stop being just numbers and more human strategies are adopted for urban planning. At the end, an image was produced to summarize the overall analysis performed.
