The Big Void as Coupled Resonance Chamber: The Grand Gallery's Hidden Twin

HYPOTHESIS: The Big Void (ScanPyramids, 2017) is not empty space, a construction ramp, or a structural feature. It is the ACOUSTIC TWIN of the Grand Gallery — a coupled resonance chamber that doubles the system's processing capability.

THE ACOUSTIC PHYSICS:

In concert hall design, coupled rooms are used to extend reverberation and enrich the harmonic content of sound. Two rooms separated by a partially transparent barrier exchange energy at rates determined by their relative volumes and the coupling area.

The Grand Gallery (47m long, 8.5m tall, 2m wide at base, 1m at top) is a tapered acoustic waveguide. If the Big Void (at least 30m long, unknown cross-section) is positioned directly above and coupled through the Grand Gallery's corbelled ceiling, the two spaces form a coupled room system that would:

1. BROADEN THE FREQUENCY RESPONSE: A single room resonates at specific frequencies. Two coupled rooms produce a wider band of resonant frequencies — critical for a system that needs to process broadband seismic input into coherent output.
2. INCREASE THE Q-FACTOR: Coupled rooms have higher Q (quality factor) — meaning sharper, more sustained resonances. Higher Q = more efficient energy conversion.
3. PROVIDE SECONDARY PROCESSING: Sound entering the Grand Gallery is filtered by the 28 resonator slots. The Big Void provides a secondary stage of processing — a second pass through a different resonant space.
4. STORE ACOUSTIC ENERGY: The Big Void may act as an acoustic energy reservoir, smoothing out fluctuations in the seismic input and providing steady-state acoustic energy to the King's Chamber.

TESTABLE PREDICTION:

If the Big Void is a coupled resonance chamber, it should have specific dimensions related to the Grand Gallery by acoustic engineering principles. When we eventually measure the Big Void's exact dimensions, they should correspond to a complementary resonant frequency — not a random construction artifact.

The ScanPyramids team has the muon data to estimate the cross-section. If it matches the acoustic coupling prediction, this would be powerful evidence for the transmitter model. This is a FALSIFIABLE prediction — exactly what distinguishes a theory from speculation.
