Zebrafish aversion to infrasound in an open field test [PDF]

open access: yesFrontiers in Behavioral Neuroscience, 2023
Aquatic species are capable of detecting infrasound (sub-20 Hz frequencies) which may be a source of anthropogenic pollution and have a detrimental impact on the environmental fitness of fish. Infrasound is generated by infrastructure, producing acoustic

Infrasound and seismoacoustic signatures of the 28 September 2018 Sulawesi super-shear earthquake [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2019
A magnitude 7.5 earthquake occurred on 28 September 2018 at 10:02:43 UTC near the city of Palu on the Indonesian island of Sulawesi. It was a shallow, strike-slip earthquake with a rupture extending to a length of about 150 km and reaching ...

Processing of volcano infrasound using film sound audio post-production techniques to improve signal detection via array processing

open access: yesGeoscience Letters, 2020
The use of infrasound for the early detection of volcanic events has been shown to be effective over large distances, and unlike visual methods, is not weather dependent.

METHOD OF STUDYING INFRASOUND WAVES FROM THUNDERSTORMS

open access: yesSolar-Terrestrial Physics, 2022
The paper provides an overview of studies of infrasound signals from thunderstorms over a period of more than 30 years. We deal with several types of infrasound signals from thunderstorms detected at the ISTP SB RAS infrasound station Badary in Buryatia.

International Monitoring System infrasound data products for atmospheric studies and civilian applications [PDF]

open access: yesEarth System Science Data, 2022
The International Monitoring System (IMS) was established in the late 1990s for verification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Upon completion, 60 infrasound stations distributed over the globe will monitor the Earth's atmosphere for ...

A basic identification of late auditory evoked potentials at infrasound frequencies: Support neural network–based signal processing

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2023
Concerns about potential health risks from infrasound exposure require objective investigation methods for the perception of infrasound by humans. Neural-network methods were applied to identify weak infrasound evoked potentials and to investigate the ...

Detections of Infrasound Waves From Water Discharges at a Hydroelectric Dam: Implementation of Timely Warnings for Unexpected Discharge Events

open access: yesGeophysical Research Letters, 2023
Water discharges at hydroelectric dams on the Imjin River, which flows through North and South Korea, generate abrupt water level increases downstream. We assessed infrasound signals from water discharges using an infrasound array located ∼32 km from the
