ANÁLISE ACÚSTICA DE PRAÇAS PÚBLICAS NA CIDADE DE JUIZ DE FORA

Abstract

This paper consists of a study based on a master’s thesis of the Post-Graduate Program in Built Environment of the Federal University of Juiz de Fora. With the growth of cities and the complexity of the urban mesh, noise pollution has become a growing harm, damaging public and environmental health. In this context, squares can act as beneficial environments to the population, helping in noise control. Therefore, this research aims to verify the noise level of the public squares in Juiz de Fora-MG, contributing to the characterization of the noise pollution of the city and assessing, indirectly, if they contribute to the wellbeing of users. To that, visits in loco were made to perform sound measurements at afternoons of weekdays in 87 squares. The values obtained were compared with those established by the NBR 10.151/2003, the World Health Organization (WHO) and results of other surveys conducted at different locations. From the data collected, it was noticed that most of the squares have higher noise levels than those suggested by the references. The contribution of this research is the gathering of the values of sound pressure level in squares, demonstrating critical points for the public authorities to initiate corrective actions.
