Traditionally, infrasound is detected by ground-based sensor arrays, which don't cover the open ocean and can be muddled by other noises, such as the wind.

These infrasound sensors can help determine falling space objects' trajectory using a method known as triangulation that compares signals received by two or more sensors to establish the location ...

Experiments conducted high in the skies over New Mexico suggest that balloon-borne sensors could be useful in detecting the infrasound signals generated by small, extraterrestrial debris entering ...

In this work, we describe the development of a man-portable “tactical” infrasound field sensor array that is small, lightweight and can be rapidly set-up and torn-down as needed. The system is able to ...

More information: Atmospheric infrasound from nonlinear wave interactions during Hurricanes Felicia and Neki of 2009, Journal of Geophysical Research - Oceans, doi: 10.1029/2012JC008257, 2012 ...

Infrasound signals generated by rising volcanic gases before an eruption could help volcanologists to better ... The Cotopaxi is therefore monitored with sensors by volcanologists to record any ...

Recording infrasound on land isn’t particularly tricky; you can place sensors pretty much anywhere. Not so in the oceans of the Southern Hemisphere: Sensors can only be placed on mostly small ...

Hank Rinehart of General Atomics Electromagnetic Systems in Huntsville, Ala., explains how his company's infrasound sensors could help improve tracking of tornadoes. Rinehart's company is teaming ...
