Uncovering the Shocking Ancient Egyptian Secrets of Sound

According to a study published on the Ancient Origins website, the Egyptians used sound to construct the Great Pyramid of Giza, using a dead end within the rock inside the pyramid room as a resonance tube that produced ultrasonic waves at a frequency of around 5 hertz. This begs the question of how important sound was to the Ancient Egyptians and whether we can find evidence of other ancient cultures using sound. The Great Pyramid of Giza does have some impressive acoustic properties, such as amplifying sounds at specific frequencies. The people who built the Giza pyramids clearly knew a lot about sound and its effects, including levitation.
