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.

本文研究了密集高层建筑的邻里景观对人类对压迫性和噪音烦恼的感知的影响。较早的研究发现，包含附近高层建筑的景观不仅会对道路交通噪音引起的烦恼产生负面影响，还会产生压迫感。然而，对于被紧密间距和间隔距离的建筑物阻挡的视线影响压迫性和噪音烦恼的反应的程度，人们的理解非常有限。此外，很少有研究探讨垂直绿化和立面条件在减弱这些反应方面的潜力。本研究旨在制定多变量模型，以预测在 55 至 65 dBA 之间的道路交通噪声水平下，在峡谷状环境中，当受到空间和立面属性的限制时，当暴露在室内被遮挡的视野中时，诱发感知压迫和噪音烦恼的概率。通过沉浸式虚拟现实向 53 名参与者展示了 16 个视听复合场景，以评估烦恼和压抑程度。结果表明，较大的间隔距离、垂直绿化的存在以及建筑物外墙的维护可以显着降低高噪声干扰响应的概率。此外，降低噪音水平、增加间隔距离、存在建筑物间距、垂直绿化和维护良好的建筑立面可能会减少压迫感。此外，该模型显示，参与者在感知噪音烦恼时，对垂直绿化的敏感度高于对视野开放性的敏感度。分离距离对感知压迫感的影响明显强于对噪音烦恼的影响。
