Avaliação dos níveis de ruído no interior dos ônibus urbanos na cidade de Campina Grande - PB.

Abstract

Currently, one of the main themes discussed worldwide is the quality of life in its different spheres. For there to be quality of life it is necessary to have a set of conditions that contribute to the physical and psychological well-being of each individual in society. The rapid increase in the number of motor vehicles has caused a significant increase in the number of complaints from the population regarding noise generated in cities, both in Brazil and in the rest of the world. Studies conducted in several cities have revealed that traffic noise is the largest contributor to measured sound levels and the biggest cause of nuisance in urban areas. In this context, this work aimed to carry out a case study in the city of Campina Grande, Paraíba, to measure the noise level inside urban buses. The study was carried out through an objective evaluation of the sound pressure level inside urban buses. Then, the collected data were analyzed to compare with the levels allowed or recommended by standard. The data were analyzed taking into account aspects such as: noise level for vehicle in motion, vehicle stopped, acoustic performance of vehicles on pavements with different types of coating, vehicles at times and peak and time out of peak. The results were satisfactory, since the average values obtained were below the limits established by norm.
