Scientists Track The Secret Sounds of Rocket Launches That Human Can't Hear - ScienceAlert

A new study details infrasounds from 1,001 rocket launches, including Space Shuttles, Falcon 9 rockets, Soyuz rockets, the Ariane 5, Russian Proton rockets, and Chinese Long March rockets.

The instruments used by the IMS are finely tuned enough to identify the individual stages of each rocket launch in some cases – though because these rockets travel faster than sound, in the example above you hear the splashdown of the boosters in the ocean before the roar of the take-off.

In rocket launches that don't go as planned, infrasonic signatures could help scientists work out why.

The 1,001 rocket launches were logged as part of 7,637 infrasound signatures captured and analyzed between 2009 and 2020 at the IMS stations.
