A small experiment found that brief exposure to very low-frequency sound raised cortisol and increased irritability even when participants could not tell the sound was present.

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.
