(above - infrasound possible cause of "haunting" feelings in Eastern State Penn, given the shape of the building and rain falling on it.)
I started off with a simple question that struck me one day when reading about infrasound (a frequency below human hearing’s ability to hear) and how ghosts supposedly communicate at this frequency range. Why, then, are we speaking to them at our Hertz level which is 800-1200 Hertz compared to their supposed 19 Hertz. If we’re having trouble hearing them, imagine what they must go through? Hmm… Well, if we’re going to believe ghosts speak at the level, then why aren’t we converting our voices to a level they can hear? For that matter, why aren’t we carrying meters to detect if that frequency is present? Yes, infrasound meters exist, like the Rion NA-18, but at a cost of 5K to 7K. Ouch!
In studying infrasound I learned a lot. Volcanoes, earthquakes, hurricanes, tornadoes, and even atomic bombs can create this frequency. Some animals use it, such as elephants, to communicate long distances because it creates great oscillations and can travel great distances easily. If you've ever felt a bass speaker from a car going by, you might have felt those vibrations through your chest. It can affect human bodies and even objects. Depending on the pitch, infrasound can cause anger and fear. It was said to be used by Hitler to incite crowds to a fevered pitch. It can cause depression, pressure in the ears, and many sensations felt in haunted locations.
What’s more, investigators of Bigfoot believe that they might communicate in this way and I think that’s a very realistic possibility. Why? If you are part of a group of creatures that are not all that common and live in giant forests, how in the world will you tell others you are available for mating over a long distance? Infrasound.
It might be also feasible to believe that infrasound is the byproduct of alien spacecraft, causing us to feel strange upon seeing them as the frequencies resonate through our bodies.
What is the future for this knowledge in the field of ghost hunting? Lots. If we can measure such infrasound conditions in a location that is haunted, then we can begin to ask ourselves—what is causing this frequency? Could this be the tie in to geomagnetic storms mixed with geology and building construction and waterways (the very things in my haunted formula?) Could this be either facilitating and energizing a haunting or giving it a pathway to express itself or perhaps causing the sensations and mind tricks that make us think there is a haunting.
Some experiments in infrasound would be in order to see just what it does to the human body in say a not-haunted location versus a haunted location. Ah, if only I had a university funding me!
