Transduction Pathway
Body Structure Resonance Response
Bar height = resonance coupling strength at the input frequency. Published resonance data: skull 300–900 Hz (Franke 1951, Békésy 1948), chest 50–100 Hz (Coermann 1962), abdomen 4–8 Hz, mandible 100–200 Hz, temporal bone conduction 200–4000 Hz (Stenfelt 2006).
Subharmonic Cascade → EEG Band Prediction
Predicted Neural Effect
EVIDENCE TIER: HYPOTHESIS. This model combines published body resonance data with nonlinear subharmonic theory to PREDICT which neural frequencies should respond to acoustic input. Predictions should be validated against actual EEG data (Sophia sessions). The transduction chain is physically plausible but not yet experimentally confirmed as a complete pathway. Mechanosensitive ion channels (Piezo1/2, TREK) are Nobel Prize-validated (2021) as biological vibration sensors.
