Sound production in the Meagre, Argyrosomus regius (Asso, 1801): intraspecific variability associated with size, sex and context [PDF]

open access: yes, 2020
Many fish taxa produce sound in voluntary and in disturbance contexts but information on the full acoustic repertoire is lacking for most species. Yet, this knowledge is critical to enable monitoring fish populations in nature through acoustic monitoring.

Shifts in acoustic signature of Southern Hemisphere fin whales: Declining peak frequency of high-frequency components [PDF]

open access: yesJASA Express Letters
Population-specific acoustic features are vital for using passive acoustic monitoring to study marine mammal populations in remote regions. Southern Hemisphere fin whale (Balaenoptera physalus) songs include region-specific high-frequency components ...

Methods to measure biological sounds and assess their drivers in a tropical forest

open access: yesMethodsX, 2022
The study of soundscapes and biological sounds is becoming the focus of increasing scientific attention. Studying biological sounds involves the deployment of acoustic sensors to record sounds and the identification of animal species and other sources of

Active and Passive acoustic logging applied to the detection of preferential flow in a sedimentary aquifer

open access: yesScience and Technology for Energy Transition, 2023
Two boreholes of an experimental site located in the Cher region (France) were investigated via Full Waveform Acoustic Logging (FWAL). The acoustic tool used for the FWAL experiments is a flexible monopole tool holding two pairs of piezoelectric ...
