In recent years, numerous studies have emphasized the crucial role of natural sounds in alleviating mental and emotional stress, as well as in restoring cognitive functions. Scientific literature has also underscored the restorative benefits of natural spaces and urban parks, leading to the development of best practice guidelines and legislation for their management. This study aims to compare different methodological approaches for assessing restorative qualities within the soundscapes of urban parks and to track changes over time. For the assessment, two evaluation methods were chosen: Attention Restoration Theory (ART), proposed by Kaplan & Kaplan [1], and the Perceived Restorativeness Soundscape Scale (PRSS), introduced by Payne [2]. The data for this study were collected over two campaigns (2012 and 2021) through interviews with visitors at the Municipal Botanical Garden and Bacacheri Park, both located in Curitiba, Brazil. A Mann-Whitney U test was employed as a statistical analysis to compare non-parametric samples.
