Abstrakt: This study focuses on noise pollution in the Botanical Garden in Curitiba, Paraná, Brazil. Equivalent noise levels (Leq) were measured at 21 points throughout the park, and interviews were conducted with park visitors. Some 47.6% of the measurement sites presented Leq levels over 65dB(A), considered by preventive medicine as the maximum tolerable exposure level without risk of health impairment, and 90.5% of the sites failed to comply with Municipal Ordinance 8,583, setting 55dB(A) as the maximum noise emission level for green areas. The results of interviews with visitors showed that 78% visit the park at least twice a week and that 96% come for physical activity. During their activities in the Botanical Garden, 24% of interviewees identified noise pollution as a source of annoyance, as compared to 22% who complained of insufficient park security.
