This paper studies the effects of neighbourhood views of densely packed high-rise buildings on human perceptions of oppressiveness and noise annoyance. Earlier studies have found that views containing close-by tall buildings would not only negatively affect annoyance induced by road traffic noises but also develop an oppressive feeling. However, there is very limited understanding about the extent to which views blocked by buildings with tight spacing and separation distance affects the responses of oppressiveness and noise annoyance. Moreover, few studies have explored the potential of vertical greening and façade condition on attenuating those responses. This study aimed at formulating multivariate models to predict the probability of evoking perceived oppressiveness and noise annoyance when exposed to blocked views from indoors in a canyon-like setting conditioned by those spatial and façade attributes at road traffic noise levels between 55 and 65 dBA. Sixteen audio-visual composite scenarios were presented to 53 participants through immersive virtual reality for annoyance and oppressiveness ratings. The results showed that the probability of high noise annoyance responses could be significantly lowered with a larger separation distance, the presence of vertical greening, and maintenance on building façades. In addition, decreasing noise level, increasing separation distance, presence of building spacing, vertical greening and well-maintained building façades were likely to reduce oppressive feeling. Further, the model revealed that participants had higher sensitivity to vertical greening than to the openness of view when perceiving noise annoyance. The effect of separation distance was significantly stronger on perceived oppressiveness than on noise annoyance.
