Should limit values be set for infrasound caused by wind turbines? [PDF]

International Journal of Occupational Medicine and Environmental Health
The study focuses on setting outdoor exposure limits for wind turbine infrasound, as most countries currently have no specific limits for this type of noise.

Perspectives and Challenges in Bolide Infrasound Processing and Interpretation: A Focused Review with Case Studies [PDF]

Remote Sensing
Infrasound sensing plays a critical role in the detection and analysis of bolides, offering passive, cost-effective global monitoring capabilities. Key objectives include determining the timing, location, and yield of these events.

Back-Azimuth Estimation of Air-to-Ground Coupled Infrasound from Transverse Coherence Minimization

The Seismic Record, 2023
We present the transverse coherence minimization method (TCM)—an approach to estimate the back-azimuth of infrasound signals that are recorded on an infrasound microphone and a colocated three-component seismometer.

Inhibition of astroglial hemichannels ameliorates infrasonic noise induced short-term learning and memory impairment [PDF]

Behavioral and Brain Functions, 2023
As a kind of environmental noise, infrasonic noise has negative effects on various human organs. To date, research has shown that infrasound impairs cognitive function, especially the ability for learning and memory.

Tracking secondary lahar flow paths and characterizing pulses and surges using infrasound array networks at Volcán de Fuego, Guatemala

Volcanica, 2021
Lahars are one of the greatest hazards at many volcanoes, including Volcán de Fuego (Guatemala). On 1 December 2018 at 8:00pm local Guatemala time (2:00:00 UTC), an hour-long lahar event was detected at Volcán de Fuego by two permanent seismo-acoustic ...

Seismoacoustic Analysis of Possible Vent‐Drying Sequence During Phreatomagmatic Activity on 13 July 2021 at Semisopochnoi Island, Alaska

Geophysical Research Letters
Pulse‐like infrasound accompanying volcanic phenomena sometimes suggests interaction with water at the crater. We focus on pulse‐like infrasound observed at Semisopochnoi Island in the Aleutian Arc, Alaska, during the phreatomagmatic activity on 13 July ...

Evaluating the applicability of a screen diffraction approximation to local volcano infrasound

Volcanica, 2021
Atmospheric acoustic waves from volcanoes at infrasonic frequencies (0.01–20 Hz) can be used to estimate source parameters for hazard modeling, but signals are often distorted by wavefield interactions with topography, even at local recording distances (

Monitoring Zoo Elephant Rumble Activity Using Combined Seismic and Acoustic Data. [PDF]

Ecol Evol
At the Opel‐Zoo in Germany, we studied elephant rumble activity by recording low‐frequency signals with seismic and infrasound sensors. We detected over 1350 rumbles within 4 weeks that show temporal patterns, demonstrating the benefits of combining both sensing methods.
