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.

Autocorrelation Infrasound Interferometry
Journal of Geophysical Research: Solid Earth, 2021 AbstractSeismic and infrasound multistation ambient‐noise interferometry has been widely used to infer ground and atmospheric properties, and single‐station and autocorrelation seismic interferometry has also shown potential for characterizing Earth structure at multiple scales.

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 ...

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.

Annoyance of Audible Infrasound [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 1987 Contours of equal annoyance were determined for pure tones in the frequency range 4 – 31.5 Hz. The curves show a narrowing of the dynamic range of the ear at low frequencies. The same pattern is seen for equal loudness curves, and the results support the theory that the annoyance of infrasound is closely related to the loudness sensation.

The Mount Meron infrasound array: an infrasound array without a noise reduction system [PDF]
Geophysical Journal International, 2019 SUMMARYMeasurements of seismo-acoustic events by collocated seismic and infrasound arrays allow for studying the two wavefields that were produced by the same event. However, some of the scientific and technical constraints on the building of the two technologies are different and may be contradicting.

Progress in Biophysics and Molecular Biology, 2007 Definitions of infrasound and low-frequency noise are discussed and the fuzzy boundary between them described. Infrasound, in its popular definition as sound below a frequency of 20 Hz, is clearly audible, the hearing threshold having been measured down to 1.5 Hz. The popular concept that sound below 20 Hz is inaudible is not correct.
