Using ecoacoustics metrices to track grassland bird richness across landscape gradients
Ecological Indicators, 2021 Ecoacoustics is an emerging field that allows inferences about biodiversity trends and ecosystem health. Several acoustic indices have been developed for fast, automated assessments of ecosystem condition and are often used to assess changes in species ...

Utility of acoustic indices for ecological monitoring in complex sonic environments
Ecological Indicators, 2021 With the continued adoption of passive acoustic monitoring as a tool for rapid and high-resolution ecosystem monitoring, ecologists are increasingly making use of a suite of acoustic indices to summarise the sonic environment.

Surgical treatment of acoustic neuroma: Outcomes and indications [PDF]
Reports of Practical Oncology & Radiotherapy, 2016 Surgery for acoustic neuroma has developed over the years with a gradual improvement in outcome. The goal of surgery should be cure of the disease and a low morbidity, preserving facial nerve function - and hearing, too, whenever feasible (i.e. in small tumors).

The efficacy of acoustic indices for monitoring abundance and diversity in soil soundscapes
Ecological IndicatorsSoil ecoacoustics is a rapidly emerging field heralded as a non-invasive method for monitoring soil fauna. Ecoacoustic analysis commonly uses acoustic indices to analyse soundscapes, linking them to ‘traditional’ biodiversity value metrics such as ...

Recognition of Frog Chorusing with Acoustic Indices and Machine Learning [PDF]
2019 15th International Conference on eScience (eScience), 2019 This research explores the recognition of choruses of two co-existing sibling frog species in long-duration field recordings using false-colour spectrograms and acoustic indices. Acid frogs are a group of endemic frogs that are particularly sensitive to habitat change and competition from other species.

Soundscape components inform acoustic index patterns and refine estimates of bird species richness
Frontiers in Remote Sensing, 2023 Ecoacoustic monitoring has proliferated as autonomous recording units (ARU) have become more accessible. ARUs provide a non-invasive, passive method to assess ecosystem dynamics related to vocalizing animal behavior and human activity.

Monitoring Grassland Bird Communities with Acoustic Indices
BirdsSeveral researchers have tried to find relationships between acoustic indices and vocal animal communities to use acoustic indices as a passive monitoring method, as human-derived surveys are expensive, time-consuming, and suffer from observer bias ...

In urban national parks acoustic indices represent avian habitat quality better than avian diversity
Environmental and Sustainability IndicatorsAcoustic indices provide a statistical method to quantify and assess relationships between soundscapes and avian diversity; however, more testing is necessary before acoustic indices are accepted as suitable proxies for biodiversity.
