May 3, 2025, bolide acoustic signal recorded by infrasound station in Yellowstone National Park

This audio clip is the infrasound recorded during 1 minute on May 3, 2025, at 9:33 p.m. MDT.  The audio is the “sonified” (data converted to sound) version of the infrasound, which is a frequency below that detectable by humans.  Time is sped up by a factor of 10.  The “boom” that occurs at about the 34-second mark is a bolide—a meteor that exploded in the atmosphere.  The video that corresponds to the audio is the infrasound waveform recorded by a station in Norris Geyser Basin over that minute.
