111 Hz

In the Ħal Saflieni Hypogeum in Malta and other Neolithic chambers, acousticians have measured a strong resonance near 110–111 Hz. A deep male voice chanting in these rooms excites it directly, filling the stone with a single sustained pitch. Whether the builders intended it is unknown, and its 'devotional' reputation is a modern reading. Auriviel offers 111 Hz as a tone with a very long echo, a sound our ancestors could have stood inside. Researchers measuring the acoustics of Neolithic chambers, most famously the Ħal Saflieni Hypogeum in Malta, have reported a strong resonance near 110–111 Hz, a pitch that a low male voice can excite by chanting. Whether the builders tuned the rooms deliberately is unknown; the frequency's devotional reputation is modern. It is offered here as a resonance with a long echo, not a proven design. 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.
