Key Takeaways from the Frequency Files
- Laboratory and experimental work has repeatedly flagged a cluster of low frequencies (near ~18–19 Hz) that correlate with reports of ‘haunting’ sensations in some settings (Tandy & Lawrence, 1998; Goldsmiths Haunt project used 18.9 Hz and 22.3 Hz).
- Institutional reviews (WHO 2018; multiple systematic reviews) find limited, inconsistent evidence that sub-audible infrasound at typical environmental levels causes unique physiological harm — strongest links are to annoyance, sleep disruption and stress pathways rather than a specific infrasound pathology.
- Open, consequential unknowns remain: what mechanism would let inaudible infrasound reliably produce apparitions in some people but not others, what real-world dose/configuration matters, and whether AI-generated music or production choices could be engineered at scale to steer mood or states without disclosure.
A Low Hum in the Room
It started in the lab, late one evening. Vic Tandy and his colleagues felt it before they understood it—a creeping cold that settled into the bones, shadows flickering at the edge of sight, and that unmistakable sense of something watching from the corners. The air smelled of stale coffee and metal dust, the kind of quiet where every creak echoes. Then, measurements revealed the culprit: an infrasound peak humming through the room, inaudible but insistent (Tandy & Lawrence, 1998).
Across reports, the experiences share a pattern. People describe a sudden presence, like an unseen figure brushing past. Visual glitches appear in the periphery—fleeting shapes that vanish when you turn. Nausea hits, or a wave of unexplained sadness, paired with cold spots that chill the skin. It’s the uncanny quiet that amplifies it, where the absence of sound feels alive.
Today, this ties into a broader cultural thread. Producers, meditators, and artists like Rick Rubin talk about sound as something spiritual, a force that shapes reality. It shifts how we listen, turning odd sensations into signs of deeper layers at work.

What Witnesses and Analysts Report
In haunted spots, the stories align. Witnesses speak of fear crashing in without warning, a felt presence that raises hairs on the neck, body tremors, cold patches, and quick visual distortions—all tied to a specific place. Tandy’s lab staff described exactly this before anyone checked the frequencies (Tandy & Lawrence, 1998).
Near wind turbines, residents share their own accounts: persistent headaches, broken sleep, a pulsing inside the body, and dizzy spells. These reports fuel advocacy groups, even as debates rage over what’s really causing them.
What evidence links low frequencies to haunting sensations? Do official reviews support claims of harm from infrasound? What are the unresolved questions about AI music and frequencies? How do cultural figures like Rick Rubin fit into this? Are Solfeggio frequencies backed by science?
