Abstract
This study aims to examine the influence of natural sound (i.e. water sound and birdsong) on the perception of the enclosure in urban street canyons with varying height-to-width ratios (H/W). A 27- meter wide street was selected as a typical urban street and three levels of H/W ratios (0.5, 2, and 4) were modelled by changing the height of buildings on both sides of the street. Vegetation and water features were added to the street as visual components, while synthesized car pass-by sounds, water sounds, and bird songs were introduced as sound stimuli. A laboratory experiment was conducted in a virtual reality (VR) environment with normal hearing participants. The experiments consisted of three sessions: 1) an audio-only condition, 2) a combined audio-visual condition, and 3) a visual-only condition. Participants were asked to rate their subjective responses to stimuli in terms of the perceived pleasantness and perceived source width for the audio-only condition, the perceived enclosure, perceived spaciousness, perceived pleasantness, and perceived source width for the audio-visual combined condition, the perceived enclosure, perceived spaciousness, perceived pleasantness for the visual-only condition. Additionally, the participant's physiological responses were monitored during the experiment in terms of facial electromyography and heart rate.
