RESUMO:

Sound pollution is already considered by the World Health Organization (WHO) to be the second largest cause of pollution in the world. In a general context, urban development was accompanied by the accelerated growth of cities and the increase in the circulation of motor vehicles, causing higher levels of noise pollution. Urban environments present complex acoustic scenarios and their studies need to consider the participation of various sound sources and their impact on the population of the city. When evaluating possible solutions, the computational models become facilitators, since they make possible quick calculations, analyzes and reports. With this feature, it is possible to know the sound pressure levels at any point in a modeled area by means of direct reading on the noise map. The research problem consisted of: in what way is the traffic noise spatialized in the road system in the municipality of Natal? For this, it is hypothesized that in the municipality of Natal / RN, the arterial and collector routes are found at sound pressure levels above those recommended by the legislation. Therefore, this research has as general objective to evaluate the quality of the sound environment and its relation with the road network in the city of Natal / RN. The methodological procedures consisted of the collection of traffic data (light and heavy vehicle flow), paving maps, gauge, densely green areas and road works. After the data collection, acoustic maps processed through the SoundPLAN® Software were elaborated and analyzed. These maps were calibrated based on quantitative acoustic measurement data in loco. When analyzing the results, it was verified that the vehicular flow follows a pattern of growth based on variables such as width and length of the track. The increase in the vehicular flow generates an increase in the sound pressure levels, and consequently almost the entire municipality is above the values recommended for comfort by the current legislation
