Abstract: This paper discusses the results of a study about the influence of urban shapes on environmental noise in the city of Aracaju (Brazil). The study, which involved in situ measurements and acoustic simulations using SoundPLAN software, began with an analysis of the current acoustic scenario, followed by the creation and simulation of hypothetical scenarios in as yet unoccupied sectors of the region under study. The acoustic modeling and simulations were based on measurements of equivalent-continuous sound pressure level, LAeq, and vehicle flow data, and on the region's geometrics. The results reveal that the physical characteristics of the urban shape, such as construction density, the existence of open spaces, and the shape and physical position of buildings exert a significant influence on environmental noise. © 2011 Elsevier B.V.
