Efficiency Evaluation Method for the Devices with Infrasound Impact on Functioning of Computer Equipment [PDF]
A significant threat to critical infrastructure of computer systems has a destructive impact caused by infrasound waves. It is shown that the known infrasound generations are based on using the following devices: a Helmholtz Resonator, Generation by ...

Predicting Atmospheric Effective Sound Speed Using Synthetic Infrasound and Machine Learning
Abstract We introduce a machine learning (ML) model that reconstructs atmospheric conditions at the location of an explosive source using regionally recorded synthetic infrasound. A convolutional neural network (CNN) processes full waveforms and source‐receiver geometries to estimate the vertical profile of effective sound speed.

Propagation of sound through the Earth's atmosphere [PDF]
The infrasonic signatures generated by the main blade slap rate of a helicoper were used in an effort to detect infrasound generated by clear air turbulence.

Observational Evidence for Wind‐Driven Low‐Pass Filtering of Infrasound at Short Range
Abstract Infrasound from controlled explosions provides a unique opportunity to isolate atmospheric effects on propagation. We report observations from two campaigns in May and October 2024, each featuring 10‐ton TNT‐equivalent controlled surface chemical explosions recorded by a dense network of 31 single‐sensor stations within 23 km.

On 4 March 2020, an accidental explosion occurred at a chemical plant in South Korea, generating both seismic and infrasound signals, which were recorded by multiple sensors at distances as great as 400 km across the southern Korean Peninsula.

The Iwo-yama volcano of the Kirishima Volcanic Complex in Japan had a small phreatic eruption in April 2018, which newly formed multiple vents. The activity was recorded by two infrasound sensors and two monitoring cameras, which had been installed ...

Wind turbine acoustic standards [PDF]
A program is being conducted to develop noise standards for wind turbines which minimize annoyance and which can be used to design specifications. The approach consists of presenting wind turbine noise stimuli to test subjects in a laboratory listening ...

Decameter‐Sized Earth Impactors—II: A Bayesian Inference Approach to Meteoroid Ablation Modeling
Abstract Small asteroids and large meteoroids frequently impact the Earth, though their physical and material properties remain poorly understood. When observed as fireballs in Earth's atmosphere, these properties can be inferred from their ablation and fragmentation behavior.

Six‐Component Electromagnetic Wave Measurements of Sprite‐Associated Lightning
Abstract Low frequency electromagnetic waves emitted by sprite‐producing lightning are normally measured using vertical electric fields or horizontal magnetic fields. Here we report for the first time the simultaneous measurement of electromagnetic waves from sprite‐producing lightning in all six electromagnetic field components Ex,Ey,Ez,Hx,Hy,andHz ...
