Computational Method Can Improve Explosion Detection

The University of Alaska Fairbanks' Alex Witsil and colleagues have developed a method to better detect explosions by training computers on artificial explosion signals. Witsil explained, "We used modeling software to generate 28,000 synthetic infrasound signals, which, though generated in a computer, could hypothetically be recorded by infrasound microphones deployed hundreds of kilometers from a large explosion." The signals reflect atmospheric variances, which can change an explosion's signal regionally or globally as sound waves spread, complicating the ability to detect a remote blast's origin and type. The machine learning technique uses hundreds of single-element infrasound microphones already deployed worldwide, enabling them to detect more nuanced signals in real time. ....'
