2 Abstract The parks selected for this study are located in areas very close to streets with intense vehicle traffic, raising the hypothesis that this proximity impairs the acoustic comfort of their visitors. The purpose of this work was to investigate the sound environment of public parks in the city of Curitiba - Paraná - Brazil, 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. The findings confirm the strong influence of traffic noise on the soundscapes of the parks. Other conditions in the parks’ environments were also identified, which interfere jointly in the soundscape and in its perception, such as the spatial factors of each park, the urban setting of its surroundings, and the sounds originating inside the parks. Keywords: noise pollution, public parks, soundscapes, urban noise pollution, parks.
3 1 . Introduction The soundscape of a city is an important environmental reference of the quality of life in the urban setting (Pereira, 2003). However, the continuous technological advances of industrialization and their essential introduction into the life of society over the last century have led to considerable negative impacts on the urban soundscape, since the noises created by humanity multiply continuously through these advances (Zannin, 2002). This fact, combined with the expansion of urban populations and the lack of information and sensitiveness about the problem of noise pollution, has generated a widely diverse range of unpleasant noises that are harmful to health and that are present mainly in leisure, professional and transport (traffic) activities, diminishing and jeopardizing the quality of life, causing irritability and communication problems, and triggering disorders that alter and impair social contact (Pimentel Souza, 1997). In general, the effects of noise on human health can be divided into 3 main categories: 1) subjective effects such as irritation, disturbance, irksomeness (??), etc.; 2) effect on the development of any specific activity, such as loss of attention, sleep disturbance, interference on speech communication, etc.; 3) psico-physiological effects, such as anxiety, depression, headache, digestive malfunction, increase in blood pressure, hearing impairment, etc. (Harris, 1998; ABNT, 2000). Researchers and society in general are increasingly concerned about this issue, and there has been a surge in the development of researchers and the creation of laws and regulations to mitigate the impact of these disagreeable noises in the social environment, emphasizing the fight against this current and harmful type of pollution (Brown et al., 1994; Pandya, 2001; Zannin et al., 2002; Zannin and Szeremeta, 2003; Brambilla, 2004; Zannin et
