All around us are sounds that we cannot hear that are capable of traveling over extreme distances, even around the Earth. Just like regular sounds, these sounds carry information about what made them. This is how you could be blindfolded and still know where someone is in the room if they are talking. Dr. Elbing’s team has been listening to these sounds for 6 years with some of the detections being from explosions, earthquakes, fireballs, and tornadoes. Tornadoes have been the primary focus with the goal being to determine what exactly produces the sound and whether it can be used to improve warnings. More recently, they have begun listening for earthquakes from high altitude balloons as part of a collaboration with NASA JPL and Sandia Labs. This work uses Earth has a model for Venus to see it could be used to study the structure of Venus, which is too hot to have any sensors on the surface.
