Environmental noise avaliation of the central region Uberaba city – MG

Abstract

Noise pollution occur a sound exceeds the normal hearing limit.  The World Health Organization (WHO) said that noise pollution is the second largest pollution cause, being considered a worldwide public health problem, as it affects the population physical and mental health. Today, it is one polltution sources that more affect the health human  due to excessive noise generated by different sources. Because to the  health problems  noise pollution, the study objective  was to evaluate some points in the Uberaba - MG central region  to quantify the existing sound intensity levels and  verify if the noise levels are above the noise levels permitted,  cause impacts humans negative effects.  Sound pressure level measurements were performed according to NBR 10.151 / 2019 in 5  zones Uberaba central region and for each zone 4 points measurement were made. The measurement was performed every 1 minute, totaling 10 minutes. The sound pressure level values, the equivalent sound pressure level was obtained, which corresponds to the average noise of each location and this value was compared with the noise pollution standards. The results obtained were above those established by standards and may cause damage to the population health that is subjected to this pollution. Thus, better city urban planning city and the incorporation of control measures and sound attenuation are necessary for the community well-being.

Key words: Noise. Noise Pollution; Health Damage.
