Passive acoustic monitoring serves as a minimally invasive and effective method for biodiversity assessment, particularly in bird through the application of indices. However, use different recording devices types environmental noise (e.g., rain, wind, stream, traffic noise) lead to signal distortions that affect ecoacoustics Currently, there are no established guidelines specifying technical requirements signal-to-noise ratio (SNR) threshold accurate calculation To enhance accuracy indices assessments, this study investigated impact (rain, on In study, we selected six indices: Acoustic Complexity Index, Diversity Evenness Bioacoustic Entropy Normalized Difference Soundscape used four simultaneously record 104 h bird-sound data at same location. addition, 44 noisy signals with intensities were artificially synthesized comparison. The sound then analyze effects assessment. Our results showed (a) all affected by device used; (b) each index had sensitivities types; (c) was SNR above which effect negligible. This provides recommendations selection determines thresholds signals, contributing refinement protocols acquiring preprocessing These findings aim establish standardized acquisition future

Soundscape diversity: Evaluation indices of the sound environment in urban green spaces – Effectiveness, role, and interpretation

Ecological Indicators, Год журнала: 2023, Номер 154, С. 110725 - 110725

Опубликована: Июль 28, 2023

Urban green space sound sources play an important role in providing people with high quality recreation experiences. However, the evaluation index for urban is still limited. The main purpose of this study to propose indices soundscape diversity spaces, compare acoustic diversity, and understand spaces. In our field investigation, 30 sample sites were recorded over a five-minute period, (SDI), richness (SRI), dominance (SDO), evenness (SEI) calculated. results showed that are more suitable than indices. There significant correlation between landscape patterns, there varied relationship perception different Soundscape can be explained by existing objective indicators, which explain 55% SDI model variations, 71% SRI 43% SDO 32% SEI variations. applied future planning environment design.

Assessing the effect of human activities on biophony in urban forests using an automated acoustic scene classification model

Ecological Indicators, Год журнала: 2022, Номер 144, С. 109437 - 109437

Опубликована: Сен. 15, 2022

Monitoring biodiversity and assessing the impact of human activities using acoustics is a promising area in field urban ecology. Previous studies on are often limited by data continuity survey scope, making it difficult to answer questions about relationships between bird population dynamics environmental factors. To some extent, big methods such as continuous acoustic monitoring have bridged this gap provided new research paths address problem. In study, we proposed machine learning (ML) method that uses convolutional neural networks (CNN) target sound ratios (TSAR) quantify dominance seven types scenes. Acoustic was recorded at nine sites three forests Guangzhou, China. Using site-related data, trained network identified soundscape components with an overall F1 score 0.97, precision 0.96, recall 0.97. Spatial patterns scenes were examined understand effective working radius equipment impacts differing land use composition soundscapes. This study indicates significant interactions acoustics, demonstrates vocal organisms respond changes primarily their frequencies, proposes novel framework for utilizing monitor biodiversity. Going forth, these analyses help promote conservation sustainability development.

The potential of soundscapes as an ecosystem monitoring tool for urban biodiversity

Journal of Urban Ecology, Год журнала: 2025, Номер 11(1)

Опубликована: Янв. 1, 2025

Abstract As urbanization and densification often lead to significant biodiversity loss, understanding monitoring urban patterns is crucial. Traditional methods are costly, time-consuming, require specialized expertise. Passive acoustic soundscape ecology have emerged as promising, non-invasive techniques for ecosystem monitoring. This review aims provide an overview of approaches utilized in discuss their limitations. We highlight exemplary studies that focus on demonstrate recordings can be partially used predict cities, especially avian species. To realize the potential conservation, current challenges must addressed. includes data processing, security, missing standardized collection methods. call further research combines innovative technologies transdisciplinary develop effective conservation applications cities.

Climate change demands innovative and holistic approaches to urban design that address both the tangible intangible challenges posed by a rapidly evolving environment. This article explores necessity of transdisciplinary approach climate adaptation in spaces, emphasizing integration architecture, social innovation, more-than-human design, multisensory analysis. We examine current controversies architectural solutions adaptation. Drawing on state-of-the-art from key fields, we discuss potential Nature-based Solutions, co-creation practices, multimodal create adaptive spaces physical, emotional, needs human inhabitants. The reviews emerging frameworks case studies, including shelters, biodiversity-inclusive soundscapes smellscapes, demonstrate importance considering diverse perspectives stakeholders. By synthesizing these findings, propose an integrated framework for moves beyond traditional overlapping layers awareness, ecological diversity, cultural sensitivity.

Which Factors Enhance the Perceived Restorativeness of Streetscapes: Sound, Vision, or Their Combined Effects? Insights from Four Street Types in Nanjing, China

Land, Год журнала: 2025, Номер 14(4), С. 757 - 757

Опубликована: Апрель 1, 2025

Streetscapes play a critical role in restorative landscapes, offering opportunities for promoting public well-being. Previous studies have predominantly examined the influence of visual and auditory stimuli on perceived restorativeness independently. There is limited understanding their interactive effects. In this research, 360 participants completed series experiments considering four distinct street types, including comfort assessment, acoustic environment restorativeness. They were assigned to control group one three experimental groups, each receiving specific enhancement: stimuli, or combination audiovisual stimuli. The findings revealed that groups reported greater sense compared group. Notably, demonstrated more pronounced effect than while differences found between outcomes among types are discussed, highlighting context-specific guidelines enhancing streetscape research highlight masking soundscape environmental design. study adds novel multi-sensory approach current body providing significant insights planning design streetscapes.

Human-dominated urban ecosystems have encroached on native habitats, positioning parks as crucial sanctuaries that support bird diversity conservation. Bird communities tend to act significant indicators of habitat quality. Birds play a key role in generating soundscapes environments, where healthy acoustic environment is essential not only for human well-being but also serves core focus environmental monitoring and landscape enhancement. Previous studies pointed out indices great advantages strong feasibility long-term monitoring. However, few the comparative analysis across subject varying degrees urbanization been published this field. In study we recorded springtime soundscape 8 Nanjing (China) from March April 2023 10 hours each day. Six Acoustic Complexity Index, Diversity Normalized Difference Soundscape Bioacoustic Entropy Index Power Spectral Density were used quantify results. To investigate influence vegetation habitats activity, utilized K-means clustering categorize based their developmental gradient, while Principal Component Analysis (PCA) was employed simplify dimensions 12 factors. The results revealed distribution birds complex interplay variables including gradient development, functions park plots, characteristics among others. Day-to-day, activities show similarities, yet birds' responses environments vary by location. daily movement visitors exerts discernible birds, even those adapted life. instances heightened demonstrate proclivity seeking refuge less disturbed areas, activity space tends be concentrated higher plants. Vegetation areas high disturbance are found provide substantial habitats.
