Análise dos níveis de pressão sonora nos locais de maior incidência de ruído na cidade de Santa Maria, RS

Abstract

Sound pollution is a problem that reaches, with higher or lower intensity, all people that live in small and mainly in big urban centers. We tried to apply the Environmental Education tools in the city of Santa Maria as instruments to evaluate some places that occur problems of sound pollution, providing subsidies in order to set up bases to the projects that aim at the acoustic comfort of the citizens that live near these places. This research hás been planned to be done in two stages, in which we have listened the population that live in the chosen places, to collect information through interviews with their residents and we have done measurements of the noise of the bars, night clubs, fast food places that are more frequented on downtown and in the “Km3” and “Nossa Senhora de Lourdes” quarters in Santa Maria. Through the surveys we could observe that the persons who frequent these places don’t have any concern about the people that live near those bars, using them to have fun and besides the noise and inconvenience cause, they let these locals untransitable after the parties. We have found garbage spread on the streets like broken bottles, plastic glasses and bottles, paper napkins, fast food recipients, that causes visual pollution besides of the sound pollution already mentioned.
