Scientists Decode Earth's Hidden Acoustic Soundtrack
Researchers have captured and translated Earth's previously inaudible geological and atmospheric vibrations into a listenable acoustic experience, revealing a complex hidden soundtrack generated by everything from ocean waves to seismic activity. The project bridges geophysics and art to make planetary processes tangible to the human ear.
Key Takeaways
- Researchers shifted Earth's infrasonic vibrations into audible range, revealing a hidden planetary soundtrack
- Planet's hum oscillates at 2.9-4.5 millihertz — 10,000 times below human hearing
- Audio reveals seasonal patterns, storm signatures, and even COVID-19 lockdown effects
- Project bridges geophysics and public engagement, with museums creating immersive listening exhibits
