Abstract

Urban areas suffer several environmental perturbations as a result of human activities and technological developments that contribute to the formation of heat islands and increasing noise contamination. Environmental effects are incorporated by population in urban areas and, especially, in areas near roads with heavy traffic. This paper presents a theoretical-experimental analysis on the relationship between climatological conditions and the propagation of noise in traffic corridors with high, medium, and low intensity. Some variables, such as the width of the streets, the height of the buildings, the distance between buildings, the volume flow of vehicles offer the possibility to make traditional techniques for mitigating the air temperature increase and reduce noise levels in urban zones. The results obtained in this work by measuring temperature, humidity, and noise levels, made during certain periods of time in different parts of the city of Belem/Brazil, were linked to a database georeferenced (GIS) that allowed interpolation of data in a single platform, enabling integration between data allowing to correlate them in order to assess which typological conditions are most favorable to the thermoacoustic comfort.
