The university campus landscape is an important environmental factor affecting college students’ restorative effects. Still, current research on the campus healing landscape needs more discussion from the perspective of visual-audio interaction. The study adopts an experimental research approach, forming experimental conditions through the combination of audio-visual materials, investigating the feedback of students in different visual-audio conditions, analyzing the impact of landscape and soundscape types on students’ positive emotions, the evaluation of environmental restorativeness, and eye movement patterns. Research has found that the interactive effect of campus visual-audio landscapes on students’ positive emotions reaches a marginal significance level. Natural sound can effectively improve the healing effect of forest landscapes, while combining artificial sound and lawn or square obtains a more positive environmental restorativeness evaluation. Forest landscapes are more susceptible to the negative impact of mechanical sound. The study suggests that differences in the coordination level of visual-audio elements, specific scene sound expectations, and environmental restorativeness scales may lead to these results. The study clarifies the multi-sensory impact mechanism of the campus healing landscape, and the research results are expected to provide a reference basis for campus landscape design and management.
