Avaliação dos níveis de ruído provocados por trens em bairros residenciais próximos ao centro de Curitiba

Abstract

By many years the population that lives, works and passes by some districts of the central region of Curitiba have being disturbed by the passage of the cargo train operated by América Latina Logística (ALL). Besides provoking traffic jams and air pollution, the train emits a loud noise to warn its passage. Many times imperceptible, noise can cause since just and instantaneous nuisance to hearing loss and other organics, emotional and social chances. This case study aims to evaluate the sound pressure level emitted by the train in establishments on central districts of Curitiba, compared them to the limits established by the Law no.10.625/2002 and to the norms NBR 10.151 and NBR 10.152. To evaluate this case, 10 points such as residential buildings, a school and a church, where determined and had their sound pressure level measured with the passage of the train, representing the establishments of the affected region. The methods used on the measures where determined by the norms. The results where worrisome: all the values measured with the passage of the train are above the limits taken as reference. As a solution to the problem, some of the recommendations made are, on a short run, the installation of gates so that the train does not have to honk anymore, and, on a long run, the removal of the railway line.
