Vibrational and Frequency Healing: Sorting Signal From Noise
Sound and mechanical vibration do measurable things to human physiology. The distance between that fact and most frequency-healing claims is where the reporting has to happen.

There is a defensible version of this field and an indefensible one, and they use the same vocabulary. Distinguishing them requires asking a narrow question: is a specific physical mechanism proposed, and has anyone measured its effect on a clinical outcome?
The measurable end
Focused ultrasound uses acoustic energy to ablate tissue and modulate deep brain structures; it is FDA-cleared for essential tremor. Low-intensity vibration has been studied for bone density. Music-based interventions have reasonable evidence for anxiety before procedures and for aspects of dementia care. These are all vibrational in a literal sense, and none require a novel physics.
The unmeasured end
Claims that particular frequencies — 528 Hz is the usual example — repair DNA or resolve disease have no mechanistic basis and no supporting trials. The number's origin is numerological rather than experimental. Devices sold on this rationale are usually marketed as wellness products precisely to avoid the evidentiary standard a medical claim would require.
Sound therapy can be restful and still not be doing what the brochure says it is doing.
Between the two ends sits sound bath practice, which many people find genuinely calming. Relaxation is a real physiological state with real downstream effects. It is a modest and honest claim, and it is not the claim usually being made.
