Environmental noise has long been considered one of the unwelcome aspects of urban life at home. An increasing number of scholars have studied improving indoor acoustic comfort by using the soundscape approach. However, much uncertainty still exists about the relationship between the audio-visual environment and indoor soundscape perception. The current study investigates the interaction effects of traffic sound and window views on indoor soundscape perceptions in residential contexts. Thirty-two participants were presented with 51 scenarios (a combination of 17 window views and three aural stimuli) and requested to assess their soundscape perceptions in a VR experiment. Results showed that traffic noise could moderate the impact of nature, road, and building views on pleasantness, while it can also moderate the effect of water sound and road view on eventfulness. In particular, natural window views were found not to lead to a more pleasant indoor soundscape necessarily; natural window views even decrease the pleasantness of indoor soundscape in the case of heavy traffic noise outside the window. Besides, overall visual indicators, including complexity and openness, have an interactive effect with traffic sound on pleasantness. Last, pleasantness is found to be associated with the appropriateness of indoor soundscape.
长期以来，环境噪声一直被认为是城市生活中不受欢迎的方面之一。越来越多的学者研究通过使用景观声音的方法来提高室内声学舒适度。然而，音频-视觉环境与室内景观感知之间的关系仍然存在很大的不确定性。本研究调查了交通噪音和窗户景观对居住环境中室内景观感知的交互影响。32 名参与者在 VR 实验中展示了 51 种场景（17 种窗户景观和 3 种听觉刺激的组合），并要求他们评估其景观感知。结果表明，交通噪声可以调节自然、道路和建筑物景观对愉悦度的影响，同时也可以调节水声和道路景观对事件性的影响。特别是，自然窗户景观不一定会导致更宜人的室内景观；在窗外交通噪音较大的情况下，自然窗户景观甚至会降低室内景观的愉悦度。此外，整体视觉指标，包括复杂性和开放性，与交通噪音对愉悦度有交互作用。最后，愉悦度与室内景观的适宜性有关。
