Accelerated expansion and traffic noise

the case of the Altiplano Cabo Branco neighborhood, João Pessoa (PB)

Abstract

The elaboration of noise maps is essential for urban planning, as it helps to visualize noise pollution, which is the second most common form of environmental pollution, according to the WHO. In João Pessoa, many studies have highlighted noise pollution in eastern neighbourhoods. The aim of this study is to investigate noise pollution in the neighbourhood of Altiplano Cabo Branco, located in this region, with an intense population density. This analysis was based on a noise map of the neighbourhood. To this end, methodological steps were followed: morphological characterisation, field research, computer simulation, map validation and analysis. The results were analysed in the light of national regulations and the specificity of the urban environment. These showed that sound pressure levels are above the standards of ABNT NBR 10151:2019, especially near busy roads. This is a warning about noise in this rapidly expanding neighbourhood and its impact on the population's quality of life.
