Measuring biodiversity with sound: How effective are acoustic indices for quantifying biodiversity in a tropical dry forest?

open access: yesConservation Science and Practice
Large‐scale biodiversity conservation and management necessitate rapid assessment tools and technologies. Indices derived from passive acoustic data offer a novel solution for rapid biodiversity monitoring.

Vegetation Structure Drives Seasonal and Diel Dynamics of Avian Soundscapes in an Urban Wetland [PDF]

open access: yesPlants
Urban wetlands are acoustic hotspots where vegetation structure, hydrological dynamics, and anthropogenic noise interact, yet multi-season assessments of how vegetation influences avian soundscapes are limited.

The efficacy of acoustic indices for monitoring abundance and diversity in soil soundscapes

open access: yesEcological Indicators
Soil 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 ...

Sounding out ecoacoustic metrics: avian species richness is predicted by acoustic indices in temperate but not tropical habitats [PDF]

open access: yesEcological Indicators, 2018
Affordable, autonomous recording devices facilitate large scale acoustic monitoring and Rapid Acoustic Survey is emerging as a cost-effective approach to ecological monitoring; the success of the approach rests on the de- velopment of computational ...

Acoustic indices respond to specific marine mammal vocalizations and sources of anthropogenic noise

open access: yesFrontiers in Marine Science, 2023
Using passive acoustic methods for biodiversity conservation and effective ecosystem monitoring is hindered by laborious, human-mediated processes of accurately identifying biologic and anthropogenic sounds within large datasets.

On the use of the acoustic evenness index to monitor biodiversity: A comment on “Rapid assessment of avian species richness and abundance using acoustic indices” by Bradfer-Lawrence et al. (2020) [Ecological Indicators, 115, 106400]

open access: yesEcological Indicators, 2021
Bradfer-Lawrence et al. (2020) have used a novel modeling approach to analyze acoustic indices, working with well-replicated data from autonomous recorders, and linking the indices to the sites’ mean avian richness rather than to simultaneous bird ...

Acoustic indices are not useful for biodiversity research

open access: yesMethods in Ecology and Evolution
Biodiversity assessment using passive acoustic monitoring has historically been challenging due to the limited availability of multi‐species acoustic detectors.

Microbial Acoustical Analyzer for Antibiotic Indication

open access: yesSensors, 2022
In this study, a compact acoustic analyzer for express analysis of antibiotics based on a piezoelectric resonator with a lateral electric field and combined with a computer was developed. The possibility of determining chloramphenicol in aqueous solutions in the concentration range of 0.5–15 μg/mL was shown.
