111 Hz

Acoustic surveys of ancient ritual structures — among them the Hypogeum of Ħal Saflieni in Malta and Newgrange in Ireland — have found a dominant resonance close to 110–111 Hz. Because the builders left no record of their intent, the archaeoacoustics literature describes this as a measured property of the spaces, not a proven design goal. In contemplative sound practice 111 Hz is used as a low, steady drone for stillness and chant. Auriviel tunes audio to this fundamental for its grounding, voice-like register — offered as a listening experience, never a treatment. Independent of any tradition, controlled clinical evidence that a specific frequency produces a specific health effect is limited and mixed. Auriviel presents these tunings as music and contemplative practice. This page is for general information and relaxation. Auriviel's frequency music is not medical advice, diagnosis, or treatment, and no health outcome is claimed. If you have a medical concern, please consult a qualified professional.
