Did you know itâs against âthe rulesâ to even post a video humming inside this so called âantechamber?â Why wouldnât they want people to hear the incredible acoustics that emanate from it? Could it be because weâre not supposed to know that this mini-chamber was an acoustical filter? As Christopher Dunn states in his book âThe Giza Power Plantâ âAfter building the resonators and installing them inside the Grand Gallery, the ancient Egyptians would have wanted to focus a sound of specific frequency, that is, a pure or harmonic chord, into the King's Chamber. They would be assured of doing so if they installed an acoustic filter between the Grand Gallery and the King's Chamber. By installing baffles inside the Antechamber, sound waves traveling from the Grand Gallery through the passageway into the King's Chamber would be filtered as they passed through, allowing only a single frequency or harmonic of that frequency to enter the resonant chamber. Those sound waves with a wavelength that did not coincide with the dimensions between
the baffles would be filtered out, thereby ensuring that no interference sound waves could enter the resonant King's Chamber to reduce the output of the systemâ
