Development and Validation of a Test Platform for Spatial EcoAcoustic Technologies [PDF]

Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023
Microphone arrays and direction of arrival estimation algorithms have become increasingly capable and accessible, furthering EcoAcoustics/Passive Acoustic Monitoring (PAM) practitioners' capacity to analyse the spatial features of natural soundscapes and thereby yield richer insights into biodiversity and ecosystem health.

Sinusoidal Modelling for Ecoacoustics [PDF]

Interspeech 2016, 2016
Biodiversity assessment is a central and urgent task, necessary to monitoring the changes to ecological systems and under- standing the factors which drive these changes. Technological advances are providing new approaches to monitoring, which are particularly useful in remote regions. Situated within the framework of the emerging field of ecoacoustics,

Predicting bird diversity through acoustic indices within the Atlantic Forest biodiversity hotspot

Frontiers in Remote Sensing, 2023
The increasing conversion of natural areas for anthropic land use has been a major cause of habitat loss, destabilizing ecosystems and leading to a biodiversity crisis.

A Convolutional Neural Network Bird Species Recognizer Built From Little Data by Iteratively Training, Detecting, and Labeling

Frontiers in Ecology and Evolution, 2022
Automatically detecting the calls of species of interest in audio recordings is a common but often challenging exercise in ecoacoustics. This challenge is increasingly being tackled with deep neural networks that generally require a rich set of training ...

Using acoustic indices in ecology: Guidance on study design, analyses and interpretation

Methods in Ecology and Evolution, 2023
The rise of passive acoustic monitoring and the rapid growth in large audio datasets is driving the development of analysis methods that allow ecological inferences to be drawn from acoustic data.

Temporal Soundscape Patterns in a Panamanian Tree Diversity Experiment: Polycultures Show an Increase in High Frequency Cover

Frontiers in Ecology and Evolution, 2022
In this ecoacoustic study we used the setting of a tropical tree diversity planted forest to analyze temporal patterns in the composition of soundscapes and to test the effects of tree species richness on associated biodiversity measured as acoustic ...

A Soundscape Assessment of the Oak Forests in the National Park “Homilshanski Lisy” (Northeastern Ukraine)

Ekológia (Bratislava), 2023
We investigated the properties of the sounds recorded on the territory of the National Park “Homilshanski Lisy” (Kharkiv region, Ukraine). Recordings were made at five points (in mature, middle-aged, and young oak forests, overgrown clear-cut and aspen ...

Do acoustically detectable species reflect overall diversity? A case study from Australia’s arid zone

Remote Sensing in Ecology and Conservation, 2020
In recent years, passive acoustic monitoring has emerged as a reliable method for monitoring soniferous fauna, with numerous studies finding estimates of species richness and community composition are comparable with estimates derived from conventional ...

Ecoacoustics: A Quantitative Approach to Investigate the Ecological Role of Environmental Sounds

Mathematics, 2018
Ecoacoustics is a recent ecological discipline focusing on the ecological role of sounds. Sounds from the geophysical, biological, and anthropic environment represent important cues used by animals to navigate, communicate, and transform unknown ...
