Evaluation of Soundscapes in Urban Parks in Olsztyn (Poland) for Improvement of Landscape Design and Management

Mapping and assessing natural soundscape quality: An indicator-based model for landscape planning

Natural soundscape quality (NSQ) has been recognized as an essential cultural ecosystem service that contributes significantly to human health and well-being. It also stands as an indispensable component of environmental quality, especially for landscape aesthetic quality. However, an assessment tool for NSQ in landscape planning and environmental impact assessments is still absent. Therefore, this paper aims to address this gap by proposing an indicator-based model for assessing and quantifying NSQ in the Geographic Information System. The model characterizes NSQ based on Calmness and Vibrancy, and employs several indicators, sub-indicators, and respective metrics as proxies to quantify and map them spatially. The evaluation criteria of the model correspond to the general public's preferences for soundscape features. The case study results in Springe municipality, Germany, show that the relative values of NSQ are high in green spaces, including forests, grasslands, and shrublands, whereas they are low in open farmlands. The multiple natural sounds yield higher NSQ scores than the individual ones. The same soundscape compositions in forests and in urban parks exhibit higher NSQ scores than in other land cover types. In addition, the shares of relative values show similar distribution patterns among Calmness, Vibrancy, and NSQ according to land cover types and soundscape compositions. The evaluation results align with public values and preferences for soundscape features. Unlike subjectivist approaches, our user-independent methodology is easily transferable and reproducible. The results are comparable and communicable among the assessed areas. These endow the indicator-based model with the potential to be applied at various planning and management scales. The findings can help to incorporate soundscape evaluation into landscape planning and management systems, supporting sustainable landscape development, and providing valuable information for policy-, plan- and decision-making.

Soundscape analysis using eco-acoustic indices for the birds biodiversity assessment in urban parks (case study: Isfahan City, Iran)

Biophony and anthrophony analysis as part of the urban soundscape is an efficient approach to bird biodiversity monitoring and to studying the impact of noise pollution in urban parks. Here, we analyzed the soundscape composition to monitor the diversity of birds using acoustic indices and machine learning in 21 urban parks of Isfahan, Iran, in spring 2019. To achieve this purpose four-step method was considered: (i) choosing parks and sampling of sound and bird species; (ii) calculated the six acoustic indices; (iii) calculated the six biodiversity indices; and (iv) statistical analysis for predicting biodiversity index from acoustic indices. Three regression models including support vector machine (SVM), random forest (RF), and elastic net regularization (GLMNET) applied the acoustic indices with minimum and maximum recorded thresholds to feature extraction to measure biodiversity indicators. The optimization model was applied to reduce the independent variables. Generally, more than 18,000 samples were modeled for the dependent variables in each model. The regression results demonstrated that the highest R square was related to the songbird (0.93), evenness (0.92), and richness (0.9) indecies in the SVM model and the Shannon index (0.86) in the RF model. The results of acoustics analysis demonstrated that the Acoustic Entropy Index (H), Normalized Difference Soundscape Index (NDSI), Bioacoustics Index (BI), and Acoustic Complexity Index (ACI) indices were suitable because they could serve as proxies for bird richness and activity that reflect differences in habitat quality. Our findings offer using acoustic indicators as an efficient approach for monitoring bird biodiversity in urban parks.

The Application and Development of Mural Art in Urban Public Environment Landscape Design

With the gradual improvement of social and economic levels, cities not only meet people's basic living needs, but also have an artistic expression to a certain extent, and the public pays more attention to the beauty of the external environment. Landscapes in cities are settlement landscapes characterized by man-made landscapes, which are not only a cultural resource but also an ecological environment resource. Murals are also the first works of art of mankind. According to records, murals are the largest number of artworks in China. It is a popular work of art, representing social functions with historical value, aesthetic value, political significance, and educational function. Due to the great influence of the latest technology and emerging technology on urban art concepts, murals are widely used in urban public landscapes in Europe and America. Its grand and strong space coverage, not wasting too much space, and its imperceptible influence on vision make it the main element of urban public art. Therefore, the mural design in the urban public environment can improve China's current urban atmosphere and enhance urban characteristics. Bring the citizens a historical and cultural understanding of the urban environment they live in and enjoy art. According to the interrelationship between the city and the public environment and the human mural art, based on the relevant theoretical knowledge of urban planning and design, urban public art management, and based on the basic characteristics of human mural art, this study combines a large number of domestic and foreign cases, starting from the characteristics of the natural environment and human urban environment. This article studies the relationship between mural design and architectural design concepts and concepts in urban public environment landscape design.

Landscape Perception and the Importance of Recreation Areas for Students during the Pandemic Time

The landscape and its perception influence the quality of life of a local community. Recreation areas bring a lot of benefits to society, also in terms of mental health. Open space and contact with nature, particularly during a crisis such as the pandemic, help alleviate the effects of the lockdown and social isolation. The study objective was to determine whether and to what extent the COVID-19 pandemic influenced the importance of recreation areas and the perception of landscape among students-a social group that experiences mood disorders increasingly often and has been severely affected by the lockdown. A survey was conducted in two stages, using a Google Forms online survey. A total of 381 students from universities in Lublin participated in the survey. The survey showed that the significance of recreation areas increased during the pandemic. The perception of landscape changed as well: the value of nature, scenic views, and the therapeutic effect of the landscape began to be appreciated to a greater extent. The survey results indicate the need to ensure the diversity of green areas and improve their accessibility. Designing these areas should also consider quiet areas as well as ensuring green mobility and places of recreation.

Mining Educational Trail in Slovakia

Mining was part of the development of industrial society and a driving force of technological education and economic growth of the region. After mining ceased, many mining sites and their surrounding areas found themselves in a state of insecurity. Mining in Slovakia has had a long and rich history in the mountainous regions (e.g., Spiš, Gemer, a well-known area around Banská Štiavnica). This research is focused on the potential of the marginal mining areas Markušovce, Rudňany Poráč in the Spiš region and is oriented towards linking mining, landscape and tourism. The main analytical and synthetic research methods were supported by field research and participatory methods with a questionnaire and emotional maps. The results obtained were used in an alternative solution for eco-park case studies. The research results are operational trail models of geotourism. Further research results are concepts of eco-geoparks, which were based on the evaluation of case studies. In terms of landscape design, concepts have been specified in which landscape design dominates. Mining traces are an inseparable part of the landscape. Mining has brought its benefits but also its negatives. How do we deal with this heritage? This research responds that landscape revitalization, the development of educational tourism and the creation of a diverse environment is one of the good ways.

Soundscape Assessment of Green and Blue Infrastructures

Green and blue infrastructures provide economic, environmental, and social benefits to urban life. Various areas that are passing through such infrastructures have implications for those benefits. For instance, urban, rural, agricultural, and industrial zones extend the services and disservices of green and blue infrastructures. Such extensions also have various implications on the environment and public health. Sound is one of those under-examined aspects of aggregated effects of green and blue infrastructures. This study aims to contribute to whether soundscape is affected by three pillars of urban, industrial, and rural areas among green and blue infrastructures. The study result shows no significant difference among those zones; however, urbanized areas include the highest sound levels. Industrial and rural zones show similar patterns. The study also identified that green infrastructure has more effects on the soundscape paradigm. The results also imply that green and blue infrastructures should be designated in harmony to produce a more sound-friendly environment considering the current major uses of the areas.

The Effects of Soundscapes in Relieving Stress in an Urban Park

Urban parks are important urban public spaces that guarantee people recreation, create positive emotions and relieve stress. Emerging research has shown that natural soundscapes are associated with restorative landscapes in urban parks. However, there is still a lack of knowledge on the use of physiological indexes to evaluate the effects of natural sounds versus human-based sounds on stress relief. In this study, the three physiological indexes of skin conductance level, heart rate and heart rate variability were collected in Fuzhou West Lake Park with the help of Ergo LAB data platform, and a soundscape perception evaluation questionnaire was used to assess the degree of soundscape perceptions in the sample sites. The differences in the stress relieving effects of different urban park environments were analysed by applying the median test, the Wilcoxon test was applied to analyse the effects of soundscapes and urban park environments on relieving stress, and regression analysis was used to identify the important factors of restorative soundscapes. The results found that urban park environments provide a certain degree of stress relief, but the stress relieving effects of different urban park environments vary and that natural spaces play an important role in relieving stress. Urban park soundscapes are key to restorative environmental design, with natural sounds such as birdsong and stream sound being important factors of restorative soundscapes.

Redefinition of Park Design Criteria as a Result of Analysis of Well-Being and Soundscape: The Case Study of the Kortowo Park (Poland)

Well-being and soundscape analysis should be useful in re-design works involved in the planning of recreational areas and green spaces on campuses to improve the health of students, academics, and university staff. Proper space planning, for example, in campus parks, including the planning of soundscape zones, is important in relieving study and work stress. The aim of the study was to conduct a multicriteria analysis of the soundscape and well-being of users in the university park on campus in Olsztyn (Poland). It was important to redefine thinking about the re-composition of park space, including reduction of noise and improving well-being. The research included: 1. measurements of sound pressure levels (SPL) at selected points in two periods, 2. interview with park users and preparation of a mental map, 3. experts’ opinion on soundscape and well-being, and 4. design schemes for re-design of the park. The results of research regarding the perception of the soundscape and well-being in Kortowo park by respondents differ slightly from the results of SPL measurements. The results also confirm the difference between SPL in the leafless and leafy period. The results show a clear relationship between the perception of sounds and well-being in the park. However, in some areas near the water, where higher noise levels are reported the respondents felt quite comfortable. Finally, design schemes are proposed, based on experts’ opinions and results of the analysis.
