The perceived quality of soundscape in three urban parks in Rome.

Abstract

The present paper reports a socio-acoustic survey carried out in three large urban parks in Rome, selected on the basis of the outcome of a preliminary online survey. According to the experimental protocol applied in a previous study carried out in Milan and Naples, binaural recordings in 85 sites and interviews with 266 users of the three parks were performed only during the day in summertime. On the basis of selected acoustical descriptors, the sonic environment of the three parks was categorized and, thanks to statistical analysis, three clusters were identified. The results confirm that the sound environment in urban parks is often considered as "good" or "excellent" even if the sound pressure level is nearly always higher than the limits commonly used to define quiet areas. This is due to the influence of other factors, such as the presence of trees, natural features, and the tranquility; all of these components cannot be neglected in the assessment of the soundscape because they directly affect the psychological state of the person.
