Central and Eastern European Infrasound Network: contribution to infrasound monitoring [PDF]
Geophysical Journal International, 2022 SUMMARY The Central and Eastern European Infrasound Network (CEEIN) has been established in 2018 with the collaboration of four research institutes, the Zentralanstalt für Meteorologie and Geodynamik (ZAMG), Vienna, Austria; the Institute of Atmospheric Physics of the Czech Academy of Sciences (CAS IAP), Prague, Czech Republic; the ...

Infrasound From Large Earthquakes Recorded on a Network of Balloons in the Stratosphere
Geophysical Research Letters, 2022 The ground movements induced by seismic waves create acoustic waves propagating upward in the atmosphere, thus providing a practical solution to perform remote sensing of planetary interiors.

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.

Ambient infrasound noise [PDF]
Geophysical Research Letters, 2005 The ambient infrasound noise environment is characterized for 21 globally distributed infrasound arrays in the frequency band of 0.03 to 7 Hz. Power Spectral Density (PSD) is measured for one site of each array for 21 intervals at each of four times of day from January 2003 through January 2004.

Detecting Large Explosions With Machine Learning Models Trained on Synthetic Infrasound Data
Geophysical Research Letters, 2022 Explosions produce low‐frequency acoustic (infrasound) waves capable of propagating globally, but the spatio‐temporal variability of the atmosphere makes detecting events difficult.

Infrasound direction of arrival determination using a balloon-borne aeroseismometer.
JASA Express Letters, 2022 Free-floating balloons are an emerging platform for infrasound recording, but they cannot host arrays sufficiently wide for multi-sensor acoustic direction finding techniques.

Deep learning categorization of infrasound array data.
Journal of the Acoustical Society of America, 2022 We develop a deep learning-based infrasonic detection and categorization methodology that uses convolutional neural networks with self-attention layers to identify stationary and non-stationary signals in infrasound array processing results.
