Abstract Various auditory and visual factors influence people’s perception and restoration experiences in the spatial environments. However, few studies have treated these factors as a comprehensive system phenomenon to reveal their integrated effects. Therefore, a specific explanation of the primary pathways and factors that contribute to the main effects of park soundscapes and visual features and the resulting perceived restorativeness remains unclear. The study surveyed 861 visitors in five urban parks in China and collected audiovisual information. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), the research explored the direct, indirect, and moderating effects of common audiovisual environments in parks on perceived restorativeness, emotional states, and preferences. The results indicate that most natural-related visual and auditory factors provide direct benefits for people’s perceived restorativeness, emotional state, and preference. Additionally, certain landscape features and types of sound sources, such as trees and water sounds, have indirect effects on activating restoration through preference and emotion mediation. The study also reveals the moderating effects of landscape features and sound source types on emotional and perceived restorativeness. Another noteworthy finding is the significant relationship between bird songs and the positive impact on perceived restorativeness, emotional state, and preference, which is closely related to acoustic quality indicators. These findings offer new insights for creating urban park spaces through visual and auditory interactions. |
