Hearing the Russian meteor, in America: Sound arrived in 10 hours, lasted 10 more

How powerful was February’s meteor that crashed into Russia? Strong enough that its explosive entry into our atmosphere was detected almost 6,000 miles away in Lilburn, Ga., by infrasound sensors — a full 10 hours after the meteor’s explosion. A researcher has modified the signals and made them audible, allowing audiences to “hear” what the meteor’s waves sounded like as they moved around the globe on February 15.
