The noise measurements were taken as recommended by the Brazilian standard for noise assessment in communities [22] and also following the recommendations of Parts 1 and 2 of the ISO 1996 standard [23,24]. The equipment and software program used in the noise analysis were: 1) sound analyzers (B&K 2238 and B&K 2250), and 2) Predictor 8.11 software for acoustic map calculations. All the noise measurements were taken in good weather (without rain or strong wind). The measurements were taken in the daytime (07:01 to 19:00), between April and August 2012, with simultaneous traffic counts at different times on week days.
