The green transformation of the built environment is aimed at improving sustainability and can be supported by digitalization, which has become a significant tool to support supply, integration, management information throughout construction life cycle. In addition, climate change highly affects human comfort in different strategies should evaluated for adapting cities. This paper developed digital workflow integrating existing tools (i.e., Grasshopper, Ladybug, Honeybee, Dragonfly) evaluate how infrastructure affected thermal reducing UTCI. was applied typical historical urban context (Catania, South Italy), consisting square surrounded three-floor buildings. Three basic scenarios were created that depended on pavement material used environment: black stone (reference from Mount Etna), permeable pavement, grass. These three combined with strategies: tree pattern square, walls roofs surrounding buildings, integrations all these above-mentioned strategies. results demonstrated integration (a grass instead trees, roofs) increased UTCI more than 8 °C compared (black building envelope). However, this temperature reduction location body into evaporation rates vegetation. will useful designers effectiveness during early-design stage mitigating cities change.

Monitoring soil fauna with ecoacoustics

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2024, Номер 291(2030)

Опубликована: Сен. 1, 2024

Ecoacoustics—or acoustic ecology—aids in monitoring elusive and protected species several ecological contexts. For example, passive (PAM), which involves autonomous sensors, is widely used to detect various taxonomic groups terrestrial aquatic ecosystems, from birds bats fish cetaceans. Here, we illustrate the potential of ecoacoustics monitor soil biodiversity (specifically fauna)—a crucial endeavour given that 59% live yet 75% soils are affected by degradation. We describe sources sound (e.g. biological, geological anthropogenic) ability technology differentiate between these sounds, highlighting opportunities current gaps knowledge. also propose a roadmap for future development optimized hardware, analytical pipelines experimental approaches. Soil an emerging field with considerable improve ‘soil health’ diagnostics.

Busy Urban Soundscape Underwater: Acoustic Indicators vs. Hydrophone Data

Urban Science, Год журнала: 2025, Номер 9(4), С. 129 - 129

Опубликована: Апрель 17, 2025

Urban noise pollution extends into aquatic environments, influencing underwater ecosystems. This study examines the effectiveness of acoustic indicators in characterizing urban soundscapes using hydrophone recordings. Three indices, Acoustic Complexity Index (ACI), Diversity (ADI), and Normalized Difference Soundscape (NDSI), were analyzed to assess their ability distinguish anthropogenic natural sources. The results indicate that ACI tracks fluctuations, particularly from vehicles trams, while ADI primarily reflects transient environmental interferences. NDSI, designed differentiate biophony noise, proves unreliable settings, often misclassifying These findings highlight limitations traditional indices environments emphasize need for refined methods improve data interpretation. Thus, this aims understand indicators’ interactions with which is crucial enhancing monitoring mitigation strategies.

Опубликована: Апрель 30, 2025

In recent years, the rapidly increasing use of artificial intelligence has begun to be incorporated into many fields in academia and market. This study investigates extent which is used determining sound absorption performance materials, have practical implications improving indoor acoustic conditions. To this end, studies conducted over past ten years based on three specified keywords were examined. Various constraints applied during review process. First, titles scrutinized filter studies. Then, research articles selected, while other eliminated. Secondary identified, a field assessment was using an analysis program. The results evaluated by grouping them under different subheadings. evaluation included year conducted, methods used, any additional inferences, if available. section, comments made usability sound-absorbing shortcomings addressed. Suggestions for future also presented. intended serve as guide, particularly new field.

Soundscape for urban ecological security evaluation

Basic and Applied Ecology, Год журнала: 2024, Номер 76, С. 50 - 57

Опубликована: Фев. 22, 2024

The security of the Earth system has been extensively discussed through concept planetary boundaries, which hypothesizes Anthropocene as crisis for pushing environmental variables beyond safe limits. Cities, burgeoning population centers, warrant heightened attention to issues surrounding boundaries and ecological security. While groundwork laid change detection, acoustic or soundscape perspective is rarely considered. This paper presents abundant empirical evidence supporting feasibility leveraging a valuable lens exploring ecosystem structures, functions, their contribution human well-being. Particularly, it proposes spatialized maps practical tools implement this innovative perspective. We elaborate on two key aspects: (i) reflection evolution, enabling evaluation interactions, ecosystem's functions; (ii) attribution providing cultural services, allowing assessment its impact health. Consequently, we propose paradigms: "security in soundscape" soundscape", thereby initiated "soundscape security". Furthermore, outline generalized pathways: monitoring, encompassing long-term strategies real-time tracking perception, involving detailed surveys investigate perception public participatory sensing large-scale services. argue that integrating considerations holds promise urban initiatives pursuit sustainable cities. Moving forward, collective efforts among academics are crucial establish widely accepted protocols maximize value

Green areas in urban environments, such as parks and gardens, are known to provide benefits called “ecosystem services” the community. recreational spaces offer opportunities for physical activity, leading improved mental health of residents. For this reason, presence quality has be considered promoted sustainable planning, especially context contributing achievement cities. As biodiversity an area is indication its quality, soundecological indicators have been used assess natural areas. Due anthropogenic sounds areas, use these determine can questioned. However, vocal activity collectively singing birds during dawn chorus contributes soundscape, results a prominent biophonic component clearly seen yearly pattern. The through estimation Bird Dawn Chorus Strength potential means assessing green spaces. To demonstrate potential, pilot study presented here on annual temporal scale soundscape typical space.

An exploratory framework for mapping, mechanism, and management of urban soundscape quality: From quietness to naturalness

Environment International, Год журнала: 2024, Номер 187, С. 108699 - 108699

Опубликована: Апрель 25, 2024

Despite growing attention from researchers and governments, challenges persist in comprehensively assessing urban sound quality by integrating both quietness naturalness aspects. This study aimed to develop an innovative soundscape index that concurrently evaluates soundscapes. Our objectives included conducting mapping, analyzing influential mechanisms, identifying priority zones for environment management. We collected pressure level (SPL) raw audio data, which we computed a normalized difference (NDSI). With dataset comprising 28 explanatory variables encompassing land use, built environment, vegetation characteristics, temporal factors, employed the random forest (RF) model predict 10 indicators, including eight SPL-related indices, NDSI, QNS (quietness soundscape) index. Crucially, utilized SHAP (SHapley Additive exPlanations) values interpret RF model. Spatial variations were evident, closely associated with road networks vegetation, respectively, discernible variations.
