The silent hum that alters human perception.
The standing waves produced by the relic and amplified by the temple are measured at 18.98 Hz. This is just below the threshold of human hearing (infrasound). Exposure to this specific frequency resonates with the human eyeball, causing optical illusions, and induces feelings of awe, dread, and "ghostly" presences.
The concept of ancient structures interacting with sound, and the effects of infrasound on the human body, are deeply studied fields. Explore the real science behind archaeoacoustics and unseen frequencies below:
