Soundscape diversity of different public green spaces in cities

Soundscape of urban public green space plays an important role in urban green space sightseeing experience, but it is not clear whether there are differences in soundscape diversity of different urban green space. This study investigated soundscape diversity of 30 urban green space samples, including urban park green space, roadside green space, square green space, campus green space and residential green space. The results showed that there are differences in soundscape diversity of urban different public green spaces. In campus green space, soundscape diversity and soundscape perceived affective quality are closely related, while in urban parks and roadside green space, soundscape diversity and soundscape perceived affective quality are not significantly related. The linear regression of soundscape diversity indices and overall quality evaluation of soundscape fit well in campus green space, square green space and residential green space. The R2 of these regression equations were 0.65, 0.74 and 0.63, respectively. This study provides potential ideas for the design and management of urban different public green spaces in the future.
