Description

This study explores the effects of natural sounds, such as water sound and birdsong, on people's reactions to urban courtyards with and without the presence of sounds. A series of laboratory experiments were conducted in virtual reality (VR) environments. The first experiment investigated people's reactions to urban courtyards in terms of perceived pleasantness, perceived enclosure, and perceived spaciousness. Three-dimensional (3D) models of small and large courtyards were created with different height-to-width ratios (H/W) and features. A laboratory experiment was then conducted with three sessions: 1) audio-only, 2) audio-visual, and 3) visual-only. Additionally, the participants' physiological responses were monitored through facial electromyography (fEMG) and heart rate (HR) throughout the experiment. The second experiment focused on the restorative effects of urban courtyards. A similar experiment was conducted in VR environments and participants were asked to rate psychological restoration in each urban courtyard. Moreover, electroencephalogram (EEG) alpha waves (α-EEG) to each stimulus were measured throughout the experiment.
