EXPERIMENT 2: King's Chamber Infrasound Spectrum vs Water Table

EXPERIMENT 2: SEASONAL INFRASOUND IN KING'S CHAMBER

OBJECTIVE: Measure the acoustic spectrum inside the King's Chamber across seasons, correlating with water table depth measured by existing Giza monitoring wells.

EQUIPMENT:

  • Calibrated infrasound microphone (0.1-200Hz)
  • Standard condenser microphone (20Hz - 20kHz)
  • Triaxial accelerometer on chamber floor
  • 24-bit data logger, continuous recording
  • Water table depth logger (existing wells)
Total budget: ~$5,000-8,000

EXISTING DATA:

King's Chamber measured resonance: ~110-121Hz
(confirmed by multiple studies including Time & Mind
journal, 2008; ResearchGate 2024)
Debertolis methodology: proven at Hal Saflieni, Malta
and Gobekli Tepe, Turkey.

PREDICTED VALUES:

Primary resonance: 110-121Hz (already confirmed)
Sub-harmonic series descending toward Schumann:
121/2 = 60.5Hz, 121/4 = 30.3Hz,
121/8 = 15.1Hz, 121/16 = 7.6Hz (!)
The 16th sub-harmonic = 7.6Hz is within 3% of
the Schumann fundamental (7.83Hz).
Seasonal prediction: infrasound amplitude at 7-15Hz
should be 10-30% higher during high water table
than during low water table.

CONFIRMATION CRITERIA:

STRONG: Infrasound detected at 7-15Hz with
statistically significant correlation to water table
depth (p < 0.05, minimum 6months continuous data)
MODERATE: Infrasound detected but no clear seasonal
correlation (chamber resonance real but water link
not detectable with current reduced flow)

REFUTATION CRITERIA:

No infrasound below 30Hz detected in the chamber
under any conditions, OR infrasound present but
uncorrelated with any geological/hydrological variable
