Previous research has shown that tranquil areas in the city, such as urban parks, are usually perceived as positive and have a restorative effect on visitors. However, visitors could experience these spaces differently depending on the meaning they assign to the concept of tranquility. To investigate how individuals’ personal views on tranquility affect their perception of the sonic environment, a soundscape study was conducted in several city parks in Antwerp, Belgium. Mobile sound measurements were combined with a questionnaire survey amongst 660 park visitors. Within the survey, the participants’ viewpoint on tranquility was evaluated using their agreement with a set of previously established prototypical statements, categorizing them into one out of three main tranquility viewpoint groups: people that associate tranquility with silence, those that associate it with hearing natural sounds, or those that associate it with social relationships. Next to this, the sounds that participants had heard during their visit were noted, and their perception of the overall quality of the soundscape and the degree to which it matched their expectation were assessed. Results show that the park visitors who associate tranquility with natural sounds or to silence are more often found amongst those that report hearing mechanical sounds a lot. The same groups of visitors rate the overall quality of the sonic environment of the park more often bad to very bad. These findings suggest that park visitors pay attention more to the sounds they do not expect to hear, and that the higher their expectations about the soundscape, the more critical they become in their appraisal of the soundscape.

There are relatively few studies on the acoustic environment of care facilities. However, sound is an important component of the users’ experience and quality of life in these spaces, and particularly in nursing homes, where both staff and residents have medium- to long-term perspectives, contrarily to hospital settings. This study included an online large-scale survey for nursing homes in Flanders and it targeted the group of professionals. It aimed at providing an overview about noise sensitivity and sound perception of the staff members in their work environment, as well as investigating the potential effects on sound perception of staff role and context. Results showed that limited differences emerged for staff roles, while more differences were found when exploring the context factor. Overall, the results of this study claim for further attention on the management and design of the sound environment in these facilities.
