The COVID-19 pandemic has affected city dwellers' physical and mental health and has raised concerns about the health of urban public spaces. This field investigation research in Dalian, China, examined the perceived audio-visual environment characteristics of urban pedestrian streets with traffic noise and their influences on the environmental health of the pedestrian streets. Five indicators reflecting psychological responses to environmental characteristics (, , , , and ) were used to measure environmental health of pedestrian streets with traffic noise. The results showed that was rated the highest, and was evaluated as the lowest among health evaluation indicators. The imageability and openness of the streetscape were associated with each health evaluation indicator. In contrast, the rhythm and continuity of the street buildings had a greater effect on than the other health indicators. There were negative correlations between for traffic noise and health evaluations. Positive health evaluations were observed when was less than 55 dBA. In contrast, soundscape indicators showed positive correlations with health evaluations, and acoustic comfort and noise annoyance, rather than sound preference and subjective loudness were associated with each health evaluation indicator. In terms of the combined audio-visual factors, acoustic comfort, the quantity of greening, annoyance, sky visibility, spatial scale, and building distance were examined as the determining factors affecting health evaluations, and 55.40% of the variance in health evaluations was explained by the soundscape and streetscape indicators. The findings provide references for better understanding the relationships between healthy experience and audio-visual perceptions. Moreover, they enable environmental health quality optimisation of pedestrian spaces considering audio-visual indicators and approaches in the post-epidemic era.
新冠疫情影响了城市居民的身心健康，并引发了人们对城市公共空间健康状况的担忧。在中国大连进行的这项实地调查研究，考察了存在交通噪音的城市步行街的视听环境特征及其对步行街环境卫生的影响。使用五个反映对环境特征心理反应的指标（、、、和）来衡量存在交通噪音的步行街的环境卫生状况。结果表明，在健康评估指标中，被评为最高，而被评为最低。街景的可意象性和开放性与各项健康评估指标相关。相比之下，街道建筑的节奏和连续性对的影响比对其他健康指标的影响更大。交通噪音的与健康评估之间存在负相关。当时，观察到积极的健康评估结果。相比之下，声景指标与健康评估呈正相关，与各项健康评估指标相关的是声学舒适度和噪音烦恼度，而非声音偏好和主观响度。在视听综合因素方面，将声学舒适度、绿化量、烦恼度、天空可见度、空间尺度和建筑间距作为影响健康评估的决定因素进行了考察，声景和街景指标解释了健康评估中55.40%的方差。这些研究结果为更好地理解健康体验与视听感知之间的关系提供了参考。此外，它们有助于在后疫情时代考虑视听指标和方法对步行空间的环境卫生质量进行优化。
