Monitoramento da poluição sonora no município de Águas Lindas de Goiás

Abstract

In recent years, the municipality of Águas Lindas de Goiás has stood out for its accelerated population and economic growth. However, the disorganized urbanization process brings undesirable consequences, capable of damaging the environment and causing nuisance and inconvenience that can compromise the health of the population. In this sense, the monitoring of noise levels in urbanized areas becomes of great importance, making it possible to verify the acoustic situation of the study area, enabling the implementation of proposals to assist in mitigating measures for the problem. In order to assess the real situation in which the city of Águas Lindas de Goiás finds itself, sound pressure levels were measured in 15 points in the city, using a digital decibel meter. Through field observation, information was gathered about morphological, meteorological and traffic magnitudes in order to identify the main sources of noise pollution in the areas studied. The data collection was carried out in May 2022, totaling 4 measurements per point, in the morning and afternoon, with a 10-minute interval each measurement. With the results, it was found that all measurements obtained values well above the established by ABNT, NBR 10.151 and through the linear correlation equation identified the vehicle flow as a factor of great influence for the high levels of noise pollution in the region.
