摘要

Perceived safety is an important factor that determines the attractiveness of a place. Urban green spaces at night have low perceived safety, which dissuades people from visiting these locations. Existing literature suggests that a soundscape can convey a sense of safety in a place. However, this topic has typically been explored during the daytime, and the effects of a soundscape on perceived safety during the evening when visual perception is substantially suppressed is generally overlooked. Furthermore, existing research has typically focused on a single medium, namely sound, despite the fact that complex interactions occur between soundscapes and visual landscapes; therefore, our understanding is limited with respect to the combined auditory-visual effects on perceived safety. To better understand these auditory-visual interactions, we conducted a study to evaluate the perceived safety of 30 photographs taken in urban green spaces during the evening, as well as combinations of these photographs with three different soundscapes (singing birds, flowing water, and traditional Chinese music). The results indicated that (1) among the three soundscapes, only traditional Chinese music significantly improved the perceived safety, and (2) perceived safety could be efficiently improved with the proper combination of soundscape and visual landscape, such as by adding the sound of flowing water to a colourful man-made landscape, combining the sound of singing birds with orderly landscaped vegetation, and introducing traditional Chinese music to landscapes with man-made elements. The results of this study can provide valuable guidance for improving the perceived safety of urban green spaces.
