John Huntington, the mastermind behind the website Control Geek, and Dr. Toija Riggins conducted an experiment to see if there was any validity to the long-standing myth that infrasound can affect anxiety levels.
Infrasound, or sound below the level of human hearing, has long been postulated as a possible explanation for the feeling of free-floating anxiety that can accompany haunted locations. In fact, it has often been employed in amusement park haunted attractions. But is there any substance to this?
Check out the data for yourself, but this pair's initial findings are rather lackluster. While this might be bad for the amusement park industry, it could be good for paranormal investigators long-plagued by those seemingly ubiquitous "underground rivers" whose movement can set in motion subsonic vibrations that have us screaming into the night.
