: This frequency is near the resonant frequency of the human eye (approx. 18 Hz), which can cause vibrating vision that creates "gray apparitions" or peripheral hallucinations.
The use of to induce anxiety and uneasiness is a well-documented phenomenon in psychoacoustics, most famously demonstrated in a 2003 large-scale experiment. While humans typically cannot hear sounds below 20 Hz, these waves can be physically felt and have been linked to intense emotional and physiological reactions.

: Out of 750 participants, 22% reported a surge in "odd sensations" specifically when the 17 Hz infrasound was present. Reported Symptoms : : This frequency is near the resonant frequency
In May 2003, researchers in London conducted a mass experiment by hiding a within contemporary music during two concerts. While humans typically cannot hear sounds below 20
