The impact of soundscapes in religious architecture on public psychology has garnered increasing attention in both research and policy domains. However, the mechanisms by which temple soundscapes influence public emotions remain scientifically unclear. This paper aims to explore how soundscapes in temple architectures designated as World Natural and Cultural Heritage sites affect visitors’ experiences. Considering visitors with diverse social and demographic backgrounds, the research design includes subjective soundscape evaluations and EEG measurements from 193 visitors at two World Heritage temples. The results indicate that visitors’ religious beliefs primarily affect their soundscape perception, while their soundscape preferences show specific correlations with chanting and human voices. Furthermore, compared to males, females exhibit greater sensitivity to emotional variations induced by soundscape experiences. Urban architects can enhance visitors’ positive emotional experiences by integrating soundscape design into the planning of future religious architectures, thereby creating pleasant acoustic environments.

Ensuring a sustainable and healthy human environment in university dormitories is essential for students’ learning, living, and overall health and well-being. To address this need, we carried out a series of systematic field measurements of the noise levels at 30 dormitories in three representative major urban universities in a major provincial capital city in China and designed and implemented a comprehensive questionnaire and surveyed 1005 students about their perceptions of their acoustic environment. We proposed and applied a sustainability–health-oriented, multidimensional assessment framework to assess the acoustic environment of the dormitories and student responses to natural sound, technological sounds, and human-made sounds. Using the Structural Equation Modeling (SEM) approach combined with the field measurements and student surveys, we identified three categories and six factors on student health and well-being for assessing the acoustic environment of university dormitories. The field data indicated that noise levels at most of the measurement points exceeded the recommended or regulatory thresholds. Higher noise impacts were observed in early mornings and evenings, primarily due to traffic noise and indoor activities. Natural sounds (e.g., wind, birdsong, water flow) were highly valued by students for their positive effect on the students’ pleasantness and satisfaction. Conversely, human and technological sounds (traffic noise, construction noise, and indoor noise from student activities) were deemed highly disturbing. Gender differences were evident in the assessment of the acoustic environment, with male students generally reporting higher levels of the pleasantness and preference for natural sounds compared to female students. Educational backgrounds showed no significant influence on sound perceptions. The findings highlight the need for providing actionable guidelines for dormitory ecological design, such as integrating vertical greening in dormitory design, water features, and biodiversity planting to introduce natural soundscapes, in parallel with developing campus activity standards and lifestyle during noise-sensitive periods. The multidimensional assessment framework will drive a sustainable human–ecology–sound symbiosis in university dormitories, and the category and factor scales to be employed and actions to improve the level of student health and well-being, thus, providing a reference for both research and practice for sustainable cities and communities.

Plant vegetation is nature’s symphony, offering sensory experiences that influence ecological systems, human well-being, and emotional states and significantly impact human societal progress. This study investigated the emotional and perceptual impacts of specific monocultural vegetation (palm and rubber) in Nigeria, through audiovisual interactions using facial expression analysis, soundscape, and visual perception assessments. The findings reveal three key outcomes: (1) Facial expressions varied significantly by vegetation type and time of day, with higher “happy” valence values recorded for palm vegetation in the morning (mean = 0.39), and for rubber vegetation in the afternoon (mean = 0.37). (2) Gender differences in emotional response were observed, as male participants exhibited higher positive expressions (mean = 0.40) compared to females (mean = 0.33). (3) Perceptual ratings indicated that palm vegetation was perceived as more visually beautiful (mean = 4.05), whereas rubber vegetation was rated as having a more pleasant soundscape (mean = 4.10). However, facial expressions showed weak correlations with soundscape and visual perceptions, suggesting that other cognitive or sensory factors may be more influential. This study addresses a critical gap in soundscape research for monocultural vegetation and offers valuable insights for urban planners, environmental psychologists, and restorative landscape designs.

Urban noise pollution significantly degrades people’s health and well-being and, furthermore, traditional noise reduction strategies often overlook individual perception differences. This study proposed to explore the role of eco-acoustic indices in capturing the interplay between biophony, geophony, and anthrophony, and their relationship with classical acoustic metrics and the perceived soundscapes within a University Campus (University of “Mila-no-Bicocca”, Italy). The study area is divided in to eight different sites in “Piazza della Scienza” square. Sound measurements and surveys conducted in June 2023 across four paved sites and adjacent courtyards involved 398 participants (51.7% female, 45.6% male, 2.7% other). The main noise sources included road traffic, technical installations, and human activity, where traffic noise was more prominent at street-level sites (Sites 1–4) and technical installations dominated underground courtyards (6–8). Human activity was most noticeable at Sites 4–8, especially at Site 5, which showed the highest activity levels. A circumplex model revealed that street-level sites were less pleasant and eventful than courtyards. Pairwise comparisons of noise variability showed significant differences among sites, with underground locations offering quieter environments. Eco-acoustic analysis identified two site groups: one linked to noisiness and spectral features, the other to intensity distribution metrics. Technical installations, people, and traffic noises showed distinct correlations with acoustic indices, influencing emotional responses like stimulation and liveliness. These findings emphasize the need to integrate subjective perceptions with objective noise metrics in soundscape descriptions. Full article

Streets play a crucial role in shaping urban soundscapes, influencing individual wellbeing and urban sustainability. Although urban soundscapes have been widely studied, research focusing on street soundscapes remains limited. This scoping review aims to provide a comprehensive analysis of the main themes and methodologies used in recent street soundscape literature. Scopus and ScienceDirect databases were searched for journal articles and conference papers with the keywords “street and sound”. The review included articles published in English between 2000 and 2025. The selected studies focused on soundscapes in outdoor environments while offering insights into streetscape features. Articles that did not focus on perception of the street environment or report a sample size were excluded, resulting in 16 studies in the final review. Soundscapes were mostly examined in terms of noise annoyance (n = 6) and sound perception (n = 14), distinguishing between pleasant and unpleasant sounds. Natural elements are frequently identified as essential streetscape (n = 8) and soundscape components of streets (n = 3). These features are associated with positive perceptions, whereas traffic features are perceived negatively. The predominant methodological approach was laboratory studies (n = 10), with participant groups typically consisting of healthy adults. Sample sizes ranged from 10 to 1200. Overall, the literature points to a significant gap in research on the effect of street soundscapes on wellbeing, revealing that numerous streetscape characteristics remain unexplored and the link between soundscapes and street features has not been thoroughly examined.

The acoustic environment of urban forests is indispensable for urban residents’ nature-based recreation opportunities and experience of green spaces, and the perceptual and physical sound features in time and space serve as determinants during this process. However, their spatiotemporal variation mechanisms and influential landscape characteristics are still underexplored in urban forests. Thus, this study aims to explore the spatiotemporal variability of perceptual and physical sound features and their relationship with landscape characteristics in urban forests. For this purpose, we measured perceptual sound features using the indicators of the sound harmonious degree (SHD) and soundscape pleasantness and eventfulness. The physical acoustic features were determined using sound-level parameters for measuring the sound level intensity (L_Aeq, L₁₀, L₉₀) and fluctuation (L_10–90). Perceptual and physical sound data collection was based on on-site questionnaire surveys and acoustic instrument measurements, respectively. The landscape characteristics were classified using the principal components of four main categories, including the terrain, area proportion of land cover types, distance to land cover types, and landscape patterns. The results showcase that significant spatiotemporal variation was found in most perceptual and physical sound features, whereas soundscape pleasantness and eventfulness did not vary significantly across time. In general, the variabilities of both perceptual and physical sound features were affected more by the types of spatial functions than by diurnal patterns. Human activities that generate sounds (e.g., hawking, playing, and exercise) may be the key drivers for spatiotemporal changes in physical acoustic features. The components of landscape patterns, including landscape structural diversity and shape complexity persistently, affected specific sound features in all periods. However, no landscape component had persistent cross-spatial influences on the sound features. This study offers critical insights into the spatiotemporal patterns of the acoustic environment and its relationship with landscape characteristics in urban forests. The findings underscore the practical importance and implications of integrating acoustic considerations into urban forest management. By providing a scientific foundation, these results can usefully inform dynamic resource management, functional zoning optimization, and sustainable landscape development in urban forests.

The restorative effects of soundscapes on human physical and mental well-being are widely recognized, but their effectiveness is influenced by various factors, including external environments and individual characteristics. Despite being a crucial element in environmental experience, the role of individual behavior in the restorative effects of soundscapes has been insufficiently studied. To address this research gap, we conducted a survey in five parks in Fuzhou, China, using questionnaires to assess visitors’ evaluations of soundscape characteristics, their soundscape restorative experiences, and behavioral characteristics. A total of 419 valid responses were collected. Using these data, we employed a structural equation model and conditional process analysis to explore the interaction between visitor behavior and soundscape experiences. The results show that soundscapes with pleasantness and eventfulness promote static behaviors to a certain degree, while dynamic behaviors are influenced solely by eventfulness soundscapes. In the process by which soundscape characteristics influence restorative experiences, static behavior is the only mediating factor, accounting for 8% of the total effect. Additionally, increased visit intensity enhances the impact of pleasantness soundscape on restorative experiences while weakening the mediating effect of static behavior. These findings provide strong support for relevant design considerations. Full article

The urban soundscape contributes significantly to defining human perception and experience. Several standard assessment methods for data collection refer to in situ evaluations to determine how people perceive urban acoustic qualities. These methods, which generally involve soundwalks accompanied by questionnaires, are valuable but need to be validated in different cultural contexts. To address this need, international efforts such as the Soundscape Attribute Translation Project (SATP) are underway to ensure the effectiveness of a data collection standard in non-English-speaking regions. As a part of the SATP project, this study explores potential variations in how people experience urban soundscapes in North Africa. A standardized listening experiment was used to compare how Arabic speakers and French speakers rate the perceived affective qualities (PAQ) of urban soundscapes. Using data collected in public urban spaces in London, participants from both language groups rated 27 recorded urban soundscapes using a PAQ questionnaire. Findings from the Kruskal–Wallis H-test suggest that the perception of pleasant, chaotic, and vibrant are significant, while the dimensions of eventful, monotonous, and quiet show no significant distinctions between the two PAQ groups. Furthermore, opposing Pearson correlations were observed for the attributes of pleasantness and eventfulness, along with contradictions for vibrant, monotonous, and calm. The two-dimensional circumplex models visually map the differences in perceptual responses between the two PAQ groups, displaying distinct circular distortions along the monotone-vibrant axis for Arabic PAQs and the chaotic-calm axis for the French PAQs. The findings of this study suggest that further investigations are needed to understand whether the differences in the urban soundscape perception between these two PAQs are due to linguistic factors or other factors.

Humans perceive their surrounding environments largely through their experiences of sight and hearing. The perceived environmental information then brings on neurophysiological changes, so as to influence human emotions. These mutually influenced relations have been widely utilized by many environmental psychologists to explore potential avenues for improving human emotions through design interventions. However, to date, no efficient and accurate way has been established to describe these relationships. Inspired by Russell’s model of emotion, this study aims to develop an efficient process that uses coordinate mapping and can intuitively describe the impact of visual-aural perceptive attributes on human emotions. Taking typical urban green spaces (UGSs) in Chengdu as examples, this study first measured the visual and aural characteristics of study sites perceived by people and their emotional responses. The study then established the use of emotional status on a coordinate axis, allowing each visual-aural attribute corresponding to each emotional response to be projected onto the coordinates. Results suggested that the dataset composed of 279 evaluations could be classified into three distinct types of visual-aural settings and the distribution of emotions is evidently varied in different settings. It was found that aesthetic and order of visual aspects as well as eventful and harmonious soundscape in environments are more likely to make people feel pleasure, while openness and layering of the visual landscape can easily arouse people’s positive status. The research outcome broadens the practical path of soundscape research, centring on human emotions, experiences and feelings, such as the pleasantness and arousal raised in Russell’s theory of emotion. The study also makes an empirical contribution to the design of UGSs based on multi-sensory perception and serves the purpose of improving people’s environmental experiences. Full article

The acoustic landscape directly affects people’s perceptual experience, which is crucial to enhancing urban greenways’ visibility experience. This study analyzed data from three typical urban greenways in Fuzhou City. By classifying and combining the landscape space into two levels of “enclosure–coverage”, the space was categorized into six types: covered, uncovered, open, semi-open, semi-enclosed, and enclosure space. We explored the characteristics of soundscape perception and the factors affecting the evaluation of soundscape perception in different landscape spaces. The results showed that differences in sound sources between day and night led to differences in the soundscape of different spatial types. The sound pressure level decreased with an increasing degree of enclosure and coverage. The evaluation scores of sound source perception and soundscape perception were significantly different in different degrees of spatial enclosure and coverage, where the open space and covered space were the most sensitive to sound, and the open space played a positive role in enhancing the harmony of the artificial sound. Pleasantness and richness were the main factors influencing overall perception, contributing 50% and 17%, respectively. Visitors’ age, residence type, and visit frequency were the main factors affecting the evaluation of soundscape perception. The conclusions provide a reference and data for improving urban greenways’ soundscape quality. Full article

Soundscape quality in green spaces of residential areas directly contributes to residents’ quality of life. It has close relationships with landscape characteristics, which should be considered in landscape planning and design processes in residential areas. Accordingly, this study proposed a new perspective on the interrelationships between soundscape perception and landscape pattern on multi-scale, based on a case study of 30 residential green spaces in Fuzhou, China. Percentage of Landscape (PLAND), Patch Density (PD), Landscape Shape Index (LSI), and Patch cohesion index (COHESION) were utilized to represent the landscape pattern of vegetation, buildings, and roads in the residential areas. Soundscape perception was interpreted using the sound dominant degree (SDD) of sound sources and overall soundscape quality. The examined spatial scales range from 20 m to 180 m, with concentric circles spaced 20 m apart for each sampling point. Correlation analyses indicated that most landscape indices of vegetation and buildings were correlated with these soundscape perception indicators, while limited landscape indices of roads were associated with them. Based on the multi-scale landscape indices, multiple linear regression models for the SDD of sound sources and overall soundscape quality were established, confirming that the scale effect of landscape patterns can affect soundscape perception. Expressly, results indicated that these models were chiefly influenced by the landscape indices at a scale less than 120 m, but the scale effect of landscape pattern on the SDD of birdsong, pleasantness, and quietness was not so evident. Furthermore, we found that the number of explanatory variables may somewhat affect the model performance. The overall interpretability of these landscape indices for the SDD of sound sources was better than that of overall soundscape quality, implying the complexity of the latter. This study offers a fresh insight into the relationship between landscapes and soundscapes at varying scales. The findings can provide useful information for the promotion strategies of landscapes and soundscapes, especially in residential green spaces. Full article

The acoustic environment can influence people’s perceptions and experiences and shape the soundscape. The soundscape has a unique role in shaping the cultural identity of a regional culture. Artificial sounds are an essential source of sounds in historical blocks; research has shown the influence of the ratio of perceived artificial sounds to the perceived extent of natural sounds on environmental perception in historical blocks. In order to explore this impact, this study uses the red soundscape index (RSI_n), which represents the ratio of perceived artificial sounds to natural sounds, and constructs a structural equation model to elucidate the relationship between RSI_n, soundscape perception, and sense of place. The results show that: (1) The evaluation of the sense of place is inversely related to the perception of artificial sounds and positively related to the perception of natural sounds. (2) Different artificial sounds have different effects on soundscape perception and the sense of place; the traditional culture soundscape index (TRSI_n) has a significant impact on soundscape pleasantness (β = −0.13, p < 0.001) and soundscape quality (β = −0.09, p < 0.01). (3) The human soundscape index (ARSI_n) has a significant impact on the sense of place (β = −0.14, p < 0.001). (4) The music soundscape index (MRSI_n) has a significant negative impact on soundscape quality (β = −0.13, p < 0.05) and the sense of place (β = −0.12, p < 0.05). Therefore, the different dominant artificial sound sources should be considered and emphasized when designing and optimizing the soundscape of historic districts. The results of this study can serve as design guidelines and supporting data, providing a reference for the optimization and enhancement of the soundscape of historical blocks. Full article

A comprehensive and scientific recognition and evaluation of landscape resources is an important prerequisite for the sustainable development of global geoparks, but the existing research lacks specific means and methods. In the case of the Koktokay Global Geopark (GGp), for example, in this study, we used GIS spatial analysis, SBE, and a questionnaire survey method to construct a comprehensive evaluation path and method for an audio-visual landscape for global geoparks and further built an audio-visual preference matrix. The research results show the following: (1) The Shenzhong Canyon scenic area has the best visual evaluation effect, whereas the Golden Triangle has the worst evaluation effect. (2) Tourists are generally satisfied with the soundscapes of the ten scenic locations in the Koktokay GGp. In addition, tourists do not think that a higher or lower volume of a soundscape would make their experience more comfortable or pleasant, so an increase in the threshold value of the sound level to a level that tourists can bear while traveling is possible. (3) The Shenzhong Canyon area is located in the key landscape area; the Aiguzi Mine and Cocosuri are located in the landscape natural development area; the No. 3 Mine Pit, Eremu Lakes, the Golden Triangle, and the Karadrola Falls are located in the landscape subpriority improvement area; and the Waterfall Fossil, Betula Forest, and Karashanger Earthquake Fault Zone are located in the landscape priority improvement area. The comprehensive audio-visual landscape evaluation method constructed in this study provides a methodological tool for evaluating other similar landscapes and provides professional guidance for the protection and development of geoparks.

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. Full article

Soundscape is an essential component of urban forest landscapes, acoustic indices can be effectively used to monitor biodiversity, but whether they can be used for soundscape perception assessments needs to be further explored. In this study, soundscape recordings were collected in Beijing Eastern Suburban Forest Park, and acoustic indices were used to explore the relationship between the acoustic environment and soundscape perception, as well as the possible effects of temporal changes. To achieve this, audio recordings collected in spring and summer were divided, and a total of 90 audio segments were extracted from three time periods—morning, afternoon, and evening—to calculate the acoustic index and complete a questionnaire survey. The urban forest soundscape was evaluated according to the eight perceptual attribute quality indicators of ISO 12913, and generalized linear models were constructed to quantify the relationships between the acoustic indices and perception. The results showed that the temporal variation of the soundscape influenced the subjective evaluation, with the highest overall evaluation relating to the morning soundscape. The combination of acoustic indices explained the soundscape pleasantness (R² = 0.58) better than the soundscape eventfulness (R² = 0.54), demonstrating the utility of these indices in soundscape assessment. Linking acoustic indices to human perception generates innovative ideas and theoretical support for soundscape enhancement, contributing to a more pleasant acoustic environment and maximizing the social value of urban forests.
