852 Hz
Free healing-frequency, solfeggio & Om sound generator
The last tone of the original solfeggio six — a high, airy "La", ready to play.
Start at a low volume and turn up slowly. Pure tones can sound louder than music at the same setting, especially higher frequencies.

852 Hz is the "La" of the original six-tone solfeggio set, named after the hymn line "Labii reatum". In Joseph Puleo and Leonard Horowitz's scheme it closed the scale, before 963 Hz was added later as a seventh step. Its digits add to 15, which reduces to 6.
852 Hz is promoted for "returning to spiritual order", "awakening intuition" and "seeing through illusions", and chakra charts link it to the third eye. Those are spiritual interpretations; there is no research showing that an 852 Hz tone affects intuition or perception.
Because it is high and light, people often use it for short, alert meditation sessions or as a quiet backdrop for reflective journaling, rather than for sleep.
852 Hz sits between G#5 (830.61 Hz) and A5 (880 Hz), about 44 cents above G#5. It is a high tone: on a piano it is well above middle C, roughly where a soprano's comfortable upper range begins.
Nobody has shown that a particular frequency heals the body, repairs DNA or treats a medical condition. The specific benefits attached to each solfeggio number are claims from the books and videos that popularised them, not findings from controlled research. What is well supported is more modest: calm, steady, predictable sound that you like can help you relax, mask distracting noise and give your attention somewhere to rest. Any of these tones can do that — and so can plenty of others.
Use it for: relaxation, meditation, a calm background while you read or rest, sound exploration, or simply because you like it. Don't use it as: a treatment for any medical or mental-health condition. For a deeper look at the whole set, see the solfeggio frequency list.
It is promoted for intuition and "spiritual order", but these effects are not supported by research. People mostly use it as a light, high tone for short meditation sessions.
It lies between G#5 and A5, about 44 cents above G#5, so it does not match a key on a standard-tuned piano.
Popular charts pair it with the third-eye chakra, but frequency-to-chakra mappings are a modern invention rather than traditional teaching.
At a comfortable, low volume, yes — it is just a tone. Avoid loud levels and long sessions with high pitches, and stop if your ears feel tired or ring.
