Infrasound is an extremely low frequency sound, one which is below the 20HZ mark, and which is undetectable to the human ear. A number of animals use infrasound as a means to communicate with each other. The long list includes giraffes, whales, and elephants. It’s a form of communication in the animal kingdom that can be highly effective for significant numbers of miles.
There is another important aspect of infrasound: when it is directed at humans it can provoke a wealth of unsettling physical and psychological sensations, as well as hallucinations of both the audible and visual kind. Many are interpreted as supernatural events.
“Mysteriously snuffed out candles, weird sensations and shivers down the spine may not be due to the presence of ghosts in haunted houses but to very low frequency sound that is inaudible to humans,” reported The Associated Press in September 2003, continuing: “British scientists have shown in a controlled experiment that the extreme bass sound known as infrasound produces a range of bizarre effects in people...”
“Some scientists have suggested that this level of sound may be present at some allegedly haunted sites and so cause people to have odd sensations that they attribute to a ghost - our findings support these ideas,” noted Professor Richard Wiseman, of the University of Hertfordshire, in the U.K.
Moving on from ghosts, let’s take a look at Bigfoot. There are far more than a few reports on record where witnesses in close proximity to Bigfoot have reported feeling inexplicably terrified, nauseous, confused, disoriented, dizzy, light-headed, and physically unable to move. Hyperventilation often sets in, too. And this is all before they have even seen the creature, or have any awareness that it's in their direct vicinity.
This may not be due to sheer terror and the pounding flood of massive amounts of adrenalin coursing through the bloodstream. The culprit may be infrasound, specifically controlled, and targeted at the witnesses, by the Bigfoot creatures themselves. Sasquatch expert Scott Carpenter said of his very own encounter with a Bigfoot:
“I am not an acoustic expert or a scientist. My findings are based on observation and common sense. I think that I was under the influence of infrasound during my encounter with the Bigfoot on April 30th, 2010. The Bigfoot manipulated my perception and sanitized my memory.”
Similarly, “Miss Squatcher” notes the adverse effects of seeking Bigfoot in Elbow Falls, Alberta, Canada, in June 2013. She says: “I felt as if my chest was heavy, my breathing was shallow and I could hardly catch my breath. Was there a Bigfoot nearby producing infrasonic waves to scare the heck out of us? We will never know for sure. But I can say with certainty that something out there made me feel more fear and panic than I have ever felt before.”
While it's highly unlikely that infrasound can explain every presumed paranormal event (and, indeed, no-one - at all - is claiming that), it may well be responsible for some of the more "high-strangeness"-themed cases that occasionally turn up in the field of Bigfoot research.
Many researchers of the legendary hairy giant are highly reluctant to address the weirder aspects of Bigfoot. I know that for sure! I've debated them on that very topic, time and time again. And I can tell you that there is deep resistance to the idea that Bigfoot is anything but an unclassified ape (or possibly the presumed long-extinct Gigantopithecus).
Too bad for them. A fresh, new approach is needed, if we are to ever resolve the matter of Bigfoot. The tried and tested ways have failed. Yes, failed. FAILED. Time to move on and consider some paradigm-changing alternatives to the "it's just an ape" scenario.
Sound, Sasquatch, and spooky activity might seem like strange and unlikely bedfellows. However, in our efforts to resolve the many and varied supernatural enigmas of our world, it's important to think outside of the box. Infrasound just might be the key to solving some of those enigmas. And Bigfoot just might be at the top of the list.
