Abstract:

This paper presents a study on noise pollution in residential areas of a large Brazilian city, Curitiba. The equivalent sound level values - Leq - were measured and tabulated for 350 locations spread over residential areas. The results showed that 80.6% of the measured points exceeded 65 dB(A). Only 9.4% of the measured points satisfy the 55 dB(A) limit for residential areas during daytime (7:00am – 7:00pm), according to the environmental legislation in effect in the city.
