Abstract
An evaluation was made of the acoustic environment of the Green Line North (GLN) by noise mapping calculations. In addition, the equivalent sound pressure levels, Leq, that reach the facades of a residential building and a hospital located along the GLN, were simulated to determine the noise levels to which they are subjected. The simulated noise levels were compared with the maximum allowable noise levels established by Curitiba Municipal Law and by the Brazilian standard on Noise Assessment in Populated Areas. It was concluded unequivocally that, in the current situation, noise pollution affects the hospital and the gated community. A simulation of heavy vehicle traffic reduction was performed, aiming at evaluating the impact of this mitigation measure. Even the reduction of number of heavy vehicle to 10% of the original number proved to be insufficient to attend values established by the municipal law and the Brazilian standard.

This study describes the impact of noise pollution on two noise sensitive areas—a hospital and a gated community located along the-Green Line North-GLN
Summary
Noise in cities is a global problem, whether small, medium or large cities. Sound pressure levels in urban environments have produced harmful effects on people’s health. One in 2017 and three in 2018 show the extent of the noise problem in cities (Licitra et al, 2017; Engel et al, 2018; Asdrubali & D’Alessandro, 2018; Morillas et al, 2018). According to Fiedler and Wilhelm (2011): “In Germany, around 70% of the population is disturbed by noise”. A similar conclusion is presented by Morillas et al (2018), where they state that: “From a temporal and spatial point of view, it is recognized that the main source of noise in cities comes from road traffic”
