Mapeamento, modelagem e avaliação do ruído urbano no entorno do campus de Cornélio Procópio

Abstract

Noise pollution is a serious problem that affects the urban centers and contributes significantly to the reduction of the quality of life of individuals exposed to it. Contrary to what is expected, small towns, as in the case of Cornélio Procópio, may also suffer from this problem. This study aims to quantify, map and analyze the noise inside the campus of Cornélio Procópio UTFPR, if the noise levels show up above the permitted, propose solutions to reduce this pollution to the standard limits. Therefore, the Cadna-A software was applied for building a three-dimensional model of the region, which was fed with data as hourly vehicle traffic, speed of vehicle, type of roads, train speed, height and geometry of buildings, local relief features, among others. The realization of the simulation generated results of sound pressure level in dB (A) that was validated by field measurement. The comparison showed that the simulated values and measured were well correlated, ensuring the good fidelity of the model. Factor that allowed the model to be used to extrapolate as to propose solutions for reducing the sound pressure levels inside the campus, as these proved to be above the permitted by the standard NBR10151: 2000. Where was simulated three improvements and the one was more effective, decreasing noise levels below the standard limit was the third, who proposed the reduction of the track speed limit, the diversion of traffic of heavy vehicles (buses and trucks), the removal of parking lots located inside the campus and the construction of a wall surrounding the campus area. It concluded that the use of computer media for sound pressure analysis is very effective and highly recommended to municipalities and public bodies who need to do similar studies for better urban planning.
