Abstract :
The purpose of this work was to investigate the sound environment of public parks using a soundscape study model that analyzes not only noise but also all the types of sound of a given area, as well as other environmental factors. To this end, acoustic measurements were made in the parks under study and interviews were held with their frequent visitors. Noise measurements were conducted in 55 points, and a total of 335 people were interviewed in the 4 parks studied. The parks selected for this study are located in areas very close to streets with intense vehicle flow, raising the hypothesis that this proximity impairs the acoustic comfort of their visitors. The findings confirm the strong influence of traffic noise on the soundscapes of the parks. Noise measurements showed that in all parks, between 50 and 100% of the points evaluated displayed sound levels above 55 dB(A), the level established by Curitibaʹs Municipal Law 10625 as the limit permitted for green areas during daytime. Other conditions in the parksʹ environments were also identified, which interfere jointly in the soundscape and in its perception, such as spatial factors of each park, the urban setting of its surroundings, and the sounds originating inside the parks.
