“Healing” sound frequencies
Music can calm you. The number on it is untested.

The One Device says it emits nine “healing frequencies”, from 174 Hz for grounding to 963 Hz for a “total nervous system reset”, with 528 Hz for “cellular and DNA repair”. Short answer: small open trials found music, meditation or chanting tuned to 528 Hz eased stress compared with silence or usual care, but none compared 528 Hz with the same sound at another pitch, so they cannot show the frequency matters. We found no study of DNA repair from sound, or of The One Device.

Grades are calculated from the studies listed, by fixed rules.
The human trials compared listening to music, meditation or chanting tuned to 528 Hz with silence, standard care or a different session, so they cannot tell the frequency apart from simply listening to something calming. None was blinded. We found no trial comparing 528 Hz with the same music at another pitch on a health outcome.
We found no study in people measuring DNA or cell repair after any sound frequency.

We found no study of the One Device, or of the nine-frequency set it lists. Its labels (“DNA repair”, “clear emotional blockages”) come from the solfeggio tradition, not from trials.
