The administration of the city of Curitiba, in its environmental protection policy,
has created in 1995 the Law8583, dividing the city in urban zones with defined noise
emission limits. The legislation has been revised in 2002 into Law 10625 (EPA,
2002). Urban public Parks are classified into “green areas”, for which the diurnal
(7 P.M. to 10 P.M.) allowed limits are of Leq =55 dB(A). In order to evaluate whether
these limits are actually met, this investigation has been conducted examining the
six largest city Parks of Curitiba: 1. Public Walk Park, 2. Barigui Park, 3. S˜ao
Louren¸co Park, 4. Botanical Garden Park, 5. Tingui Park, and 6. Tangu´a Park.
