A Study of Soundscape Restoration in Office-Type Pocket Parks

High-density building environments and fast-paced working conditions in cities pose health challenges for office workers. Office-type pocket parks assume the social responsibility of providing restorative environments for office workers, and the soundscape is an essential element of such environments. However, there is limited research on soundscape restoration in office-type pocket parks. Therefore, this study focused on soundscape restoration in office-type pocket parks. First, on-site investigations explored the spatial characteristics of 55 office-type pocket parks while analysing the soundscape features of 12 representative parks. Notably, significant correlations emerged among the perceptual parameters of the soundscape. Subsequently, three dimensions were extracted through an experimental study on the restoration levels of soundscape elements in office-based pocket parks: attractiveness, coordination, and disengagement. Finally, this study explored the impact of spatial enclosures and interface characteristics on soundscape restoration levels. This revealed that the restorative effect of negative sounds, such as traffic, air-conditioning, and speech, is significantly negatively correlated with spatial enclosure. Therefore, the greater the enclosure, the lower the restorative effect of the soundscape. Birdsongs significantly enhance the attractiveness of grey spaces, whereas small fountain sounds are most coordinated in blue spaces. This study provides a reference for the design of soundscapes in pocket parks to build healthy, restorative urban environments.
