The purpose of this study was to investigate the connection between the soundscape of a forest park, restorative perception, and health benefits. In order to assess sound source perception, soundscape perception, restorative perception, and health benefits, 10 forest park environments in Fuzhou National Forest Park were chosen for sound walks. Correlation analysis, structural equation modeling, and mediating effects were used to analyze the relationships between the variables. The results showed that (1) the majority of natural sounds, like birdsong, had a positive correlation with soundscape perception with respect to being perceived as pleasant, harmonious, varied, and fluctuating; however, human-related and traffic noises had a negative correlation with perceptions of being pleasant and harmonious, and a positive correlation with perceptions of roughness. (2) The sound of running water and wind-blown leaves had strong favorable connections with emotional, cognitive, and behavioral restorative perceptions. The sound of birdsong was strongly correlated with restorative perceptions regarding emotional dimensions. The sound of wind held substantial favorable associations with emotional and cognitive restorative perceptions. Natural sounds, except for the sound of cicada chirping, had positive correlations with health benefits. The associations between human-related and mechanical sounds and restorative perception and health benefits were not statistically significant. (3) Soundscape pleasantness had a significant positive effect on restorative perceptions, and restorative perceptions had a significant positive effect on health benefits. The effect of soundscape pleasantness on health benefits was fully communicated through restorative perceptions. The annoyingness of a soundscape had no effect on restorative perception or health benefits. In the future, forest recreation activities based on soundscape perception could be carried out through the considered use of natural soundscape resources to promote health benefits.

Studying the impact of various factors on environmental perception is crucial because humans live in an environment where these factors interact and blend. The thermal-acoustic environment is the major factor that affects the overall perception of urban parks. This study focuses on urban parks in the subtropical region, with Xihu Park in Fuzhou, China, as the research area. Through measurements and questionnaires, this study explores the effects of the thermal-acoustic environment in urban parks on subjective evaluation (thermal assessment, acoustic assessment, and overall environmental assessment). The results reveal that: (1) a higher temperature significantly increases the sensation of heat and lowers thermal comfort, heat acceptance, and overall thermal environment evaluation scores. The type of sound source has a significant positive impact on thermal assessment, and the higher the ranking of the sound source type, the greater its positive impact on thermal assessment. (2) Regarding acoustic evaluation, higher sound pressure level is associated with more negative subjective ratings of loudness, harshness, intensity, and excitement. In contrast, positive sound sources can enhance comfort, preference, disorder, coordination, and overall soundscape evaluation. Additionally, temperature increases tend to result in more negative harshness, intensity, and coordination ratings. The interaction between temperature and sound pressure level also significantly affects subjective loudness, harshness, and intensity. (3) Overall environmental evaluation is also affected by temperature, with increasing temperatures leading to decreased comfort and satisfaction while increasing irritation. High sound pressure environments result in worse overall irritation ratings, while positive sound sources can significantly enhance overall comfort, irritation, and satisfaction ratings. Furthermore, the interaction between temperature and sound pressure level significantly impacts overall irritation and satisfaction ratings. These findings are significant for managing and improving the park’s thermal environment and soundscape, providing a practical framework for landscape architects.

A soundscape can enhance the acoustic environment of urban areas and support the sustainable development of green spaces. This study is based on field research on plant information and a perception questionnaire conducted in 30 urban park sample sites in China. The study analysed the differences in soundscape perception among different plant spaces using three dimensions: sound source dominance degree (SDD), sound source harmony degree (SHD), and soundscape perception evaluation. Additionally, five physical indicators of plant space were selected to quantify the effects of physical characteristics of plant space on soundscape perception in urban green space (UGS). The results indicated that there were impacts on soundscape perception. The evaluation of soundscape perception between different types of plant spaces revealed notable differences, particularly in open and enclosed spaces. All eight indicators demonstrated significant differences, indicating that soundscape perception was influenced by the type of plant space. Additionally, there was a significant correlation between plant space and soundscape perception. The evaluation of soundscape perception in three dimensions was related to several factors, including the degree of spatial enclosure, crown density, average tree height, the proportion of trees and shrubs, and the number of tree species. The dominant factor affecting sound source dominance was found to be the degree of spatial enclosure, followed by the average height of trees. Additionally, the diversity of trees affected the overall soundscape perception.
