The design of the pyramids of Giza remains a mystery to researchers all over the world, so everyone seeks to present recent studies on how this miracle was built.
A recent study, published on Ancient-origins website, claims that the ancient Egyptians benefited from the "sound" in the construction of the Great Pyramid in Giza, and relied on the discovery of a dead end in the rock inside the pyramid room as a tube of acoustic resonance that generates ultrasonic waves at a base frequency within 5 Hz.
This raises the question of the importance of ultrasound for the ancients, and can we find the use of sound waves between ancient cultures elsewhere in the world?
The researchers noted that it has long been known that ultrasound affects the human brain in several different ways, which can stimulate feelings of nausea, anxiety, paranoia and awe, and for the most sensitive individuals can lead to a sense of separation from the physical world accompanied by a an out of this world sense.
The scientists have confirmed that ultrasound can produce a changing state of consciousness leading to unrealistic visual experiences and psychological visions. If this is true, were the builders of the pyramid in ancient Egypt aware of some very expressive forms of sound technology, the effect of ultrasound on human body systems? Is this why the impasse in the pharaonic chamber was deliberately designed to generate ultrasound.
