ANÁLISE ESPECTRAL DO RUÍDO NO ENTORNO DO CAMPUS CENTRO POLITÉCNICO DA UNIVERSIDADE FEDERAL DO PARANÁ SPECTRAL ANALYSIS OF NOISE AROUND THE POLYTECHNIC CENTER CAMPUS OF THE FEDERAL UNIVERSITY OF PARANÁ

TheWorld Health Organizationconsidersnoisepollutiona problem of publichealth.This paper presents a study of the sound pressure levels that reaches the campus buildings of the Polytechnic Center of the Federal University of Parana (Campus III). The evaluation was conducted according to the methodology presented in Brazilian standard NBR 10151, which established guidelines for Noise Assessment in Inhabited Areas. The results were compared to limit sound levels expressed in NBR 10151/2000 and Municipal Law 10.625/2002 of the city of Curitiba.Themeasurement timefor each point was assessed 15 minutes. Four sound calibrated analyzers were used. It follows that for an educational area, the measured values of the sound pressure levels are above the limits set by the standard and by municipal legislation. The analysisof the frequencyspectrumof the noise surrounding the campus,shows that itischaracterizedby a widerangeof frequencies, from lowtohigh frequencies. Considering themaximum sound levelsLAmaxandthe measuredsound spectraand consideringthe limit of60dB(A) establishedby the CityofCuritibaLaw10,625, the frequency bandof thenoise generatedisdominantlybetween 63Hzand12500Hz.
