In this study, the effects of individuals' environmental sensitivity and noise sensitivity on soundscape evaluations were examined through experiencing the audio-visual environments of various urban public spaces in a laboratory setting. The participants, 19-36-year-old college students and staff with normal hearing (N = 60), experienced 12 common urban open space scenarios (parks, squares, pedestrian streets, and residential public areas) for at least 3 minutes each, and completed the questionnaire, which consisted of two parts: 1) soundscape evaluations, which included the 8-dimensional perceived affective quality, overall quality, appropriateness, and perceived loudness of urban soundscapes; and 2) personal characteristics, including the Highly Sensitive Person Scale (HSPS) and Weinstein's Noise Sensitivity Scale (WNSS) for comparison. The results showed that people with higher environmental sensitivity tended to experience soundscape more pleasant and calm, while no significant effect of noise sensitivity was found for the soundscape evaluations, and a moderate correlation between environmental sensitivity and noise sensitivity was also revealed.
