Stories about sound, the body, and the machines that move it. What the published research says, what it does not, and what an hour on AVA actually feels like.
Body
- 01 What relaxing actually is Deep rest is not a mood. It is a change of state, visible in the heartbeat, and sound is one of the shortest routes into it.
- 02 Recovering, on purpose What twelve weeks of low frequency sound did for pain and disability in one small trial, and what sleep research does and does not support.
- 03 Releasing anxiety, and what the trials show Music therapy carries the strongest evidence in this field. Receptive listening outperformed playing, and duration mattered more than most people expect.
- 04 Resetting the nervous system Heart rate variability, vagal tone, and the cortisol claim we will not make. A close read of four studies, including one null result.
- 05 Meditation, what the trials actually show Forty-seven randomized trials, one number for anxiety, and what felt sound adds for people who cannot sit still.
- 06 Tech wellness, the honest version Saunas, plunges, sensory rooms and sound beds: what has evidence, what is placebo-adjacent, and why that still matters.
Frequencies
- 07 What sound is, and why you can feel it Pressure, wavelength, skin and bone. Why 41 Hz is nine metres long and why the bass is the part you feel.
- 08 Hertz, a field guide From infrasound to the top of hearing, the body's own resonances, and an honest read of 7.83 and 40 Hz.
- 09 Sound healing frequencies, checked 432 versus 440, the solfeggio story, binaural beats and singing bowls: what survives scrutiny and what does not.
- 10 Stories of sound frequencies Forty hertz in a clinic. A quarter of a hertz in an afternoon nap. Sixteen to one hundred and sixty through the hands and feet. Four numbers, four studies.
Machines
- 11 From Skille's bed to the octagon Norway in the 1980s, Toronto's 40 Hz work, the solo beds of today, and where AVA breaks from all of them.
- 12 Sound design for the body How a track is tuned for felt playback: the low band separated, the wave time-aligned head to feet, the peak set by hand.
- 13 Hardware: how a transducer moves you Voice coils, shakers versus speakers, heat, and why there are thirty-three of them under the bed.
- 14 Cymatics, seeing sound Chladni in 1787, Hans Jenny in 1967, Faraday waves, and why AVA draws its light from the signal instead of a plate.
- 15 Light that moves with sound How the brain fuses sight and sound, the flicker rules we follow, and why the visuals stay slow and dark.
Together
- 16 Fire, drums, and the first listening rooms Firelight talk, drummers in step, and cave acoustics: why shared felt sound bonds people, and why the room holds eight.
- 17 Connecting through sound Synchrony, oxytocin, silent discos versus shared bass, and what a Feel Together session is like from the inside.
Every piece cites named studies with working links. Where a claim has no study behind it, we write it as experience, not as science. This is wellness content, not medical advice.
