Traditional / experimental practice
Threshold VIII · Room of Reflection
The relation between a heard sound and the image that forms in the mind. In a light field of noise, very sparse, long-fading tones: each comes from a different direction, with long gaps between them. The beat descends from 7 Hz to 4.5 Hz and rises to 9 Hz at the end. Watch the shapes, colours or places the sounds evoke without forcing them; if nothing appears, that is part of the listening too. An experimental ritual; you can stop at any time.
A traditional or spiritual practice, not a scientific claim.
An experimental ritual. Avoid it if you have a history of dissociation, psychosis or severe anxiety. You can stop at any time.
Do not listen while driving or operating machinery.

- Spatial movement: sounds change position around your head; listen on headphones. This is not a binaural beat.
- Reverb: hall, 30% mix
In the room you can listen to each layer on its own, change its settings and save it as your own recipe.
Sound is generated on this device in real time; no files are downloaded from a server. There is a 15 s fade-in at the start and a 2 min fade-out at the end.
Compare with another sound
Hear both at the same loudness; drag the slider to the middle and they blend.
Mixed in the middle, these two sounds would create an unlabelled binaural beat: the slider crosses the middle with a short crossfade.
8 trials, half of them the same sound; get at least 7 right and the difference is audible. The result stays on this device.

No scientific claim is made; it is offered as a cultural or personal practice.
A traditional or spiritual practice, not a scientific claim.
Sound protocols and out-of-body experiences
An experimental listening ritual; not a scientific claim, and it makes no claim of astral travel or of consciousness leaving the body.
Evidence level T: Traditional/spiritual practiceWhat do we know?
- Out-of-body experience is a described neurological phenomenon; research links it to a failure to integrate bodily sensory information at the brain's temporo-parietal junction.Blanke & Arzy 2005
What don't we know?
- Evidence gapThere is no controlled evidence that sound leads to astral travel or that consciousness separates from the body.
Studies
- Blanke & Arzy 2005 · Review
A session's level is the weakest of its linked claims; it is never raised by a strong but unrelated claim.
