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

Temporal integration of infrasound at threshold. [PDF]
PLoS One, 2023 Infrasounds are signals with frequencies below the classical audio-frequency range, i.e., below 20 Hz. Several previous studies have shown that infrasound is audible as well, provided that the sound level is high enough. Hence, the sound pressure levels at threshold are much higher than those in the classical audio-frequency range.

Zebrafish aversion to infrasound in an open field test
Frontiers 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 detection of approaching lahars. [PDF]
Sci Rep, 2023 AbstractInfrasound may be used to detect the approach of hazardous volcanic mudflows, known as lahars, tens of minutes before their flow fronts arrive. We have analyzed signals from more than 20 secondary lahars caused by precipitation events at Fuego Volcano during Guatemala’s rainy season in May through October of 2022.

Measurement and Analysis of Infrasound Signals Generated by Operation of High-Power Wind Turbines
Energies, 2021 The development of wind energy and the increasing number of installed wind turbines make it necessary to assess them in terms of the nuisance of the emitted infrasound noise generated by such devices.

Quantized Constant-Q Gabor Atoms for Sparse Binary Representations of Cyber-Physical Signatures
Entropy, 2020 Increased data acquisition by uncalibrated, heterogeneous digital sensor systems such as smartphones present new challenges. Binary metrics are proposed for the quantification of cyber-physical signal characteristics and features, and a standardized ...

Remotely imaging seismic ground shaking via large-N infrasound beamforming
Communications Earth & Environment, 2023 Seismic ground motion creates low-frequency atmospheric sound (infrasound) that is detectable at remote sensor arrays. However, earthquake infrasound signal analysis is complicated by interference between multiple waves arriving at sensors simultaneously,
