Infrasound

Infrasound

Webster's Dictionary defines infrasonic, or infrasound, as "1: having or relating to a frequency below the audibility range of the human ear. 2: utilizing or produced by infrasonic waves or vibrations."

Theories on Infrasound and its Effect on Humans

Infrasound waves hug the ground, travel for long distances without losing strength, and are unstoppable. Not much amplitude is needed to produce negative effects in the human body, and even mild infrasound exposure requires several hours, or even days, to reverse symptoms.

Man-made structures, such as engines, cars, buses, trains, motorcycles, and airplanes also produce infrasound. John Cody noted that pilots exposed to infrasonic vibrations of jet chassis experience a reduction in "vision, speech, intelligence, orientation, equilibrium, and the ability to accurately discern situations, and make reasonable decisions."

Depending on the pitch, infrasound can cause physical pressure, or fear, disorientation, and negative physical and mental symptoms.

Please note there are varying degrees in the infrasound range and those that cause the most negative and damaging effects is not a common occurrence.

Infrasound disrupts the normal functioning of the middle and inner ear, leading to nausea, imbalance, impaired equilibrium, immobilization, and disorientation. Exposure to even mild doses of infrasound can lead to illness.

The Infrasound frequency may appear frequently under natural conditions. Infrasound arises when strong gusts of wind clash with chimneys or towers. I’m sure you’ve all experienced this at one time or another during your life. This heavy base sound penetrates even through very thick walls. Such sound waves start rumbling in tunnel-shaped corridors.

Long pipe organs, such as those found in churches and cathedrals produce infrasound. In one UK study, the extreme bass frequencies instilled strange feelings at a concert hall. Effects were "extreme sense of sorrow, coldness, anxiety, and even shivers down the spine." (source; Organ Music Instills Religious Feelings,' by Jonathan Amos, 9/8/2003)

Some cars are equipped with a boom device known as a burp button. These devices generate large amplitude pressure/low frequency noise. When the “burp button” is used, it activates a low-band pass-filter which forces all of the amplifier's power through the sub-woofer speakers at frequencies lower than a certain number of Hertz. At extremely low frequencies, it becomes infrasound. Thus you feel the blast of noise, as well as hear it. Which may explain why some humans like booming subwoofers in their vehicles and/or homes, and it is not just a “cool and popular” status meaning as we as a society have come to believe. We've all tried to block the sound from these cars when next to them stopped at a traffic light. Rolling up the window to block the sound doesn't work, because you still continue to feel the vibrations and of course, how much it annoys us.

Infrasonic vibrations which can be harmful can also be pleasantly stimulating in mild levels. The effects of brief, mild exposure can give a feeling of invigoration for hours. While a person may feel invigorated and euphoric, his body is being subjected to an elevated heart rate, elevated blood pressure, and a release of endorphins which is similar to the "fight or flight" adrenaline response. Feeling the effects of high-intensity/low-frequency sound can actually become an addiction, partially due to the release of endorphins in the body.

Interestingly, Walt Disney and his artists accidentally experienced infrasound on one occasion. A cartoon sound effect was slowed from 60 cycles per second to 12 cycles per second via a tape-editing machine and was amplified through the theater system. The resulting tone, though brief in duration, produced in the entire crowd nausea that lingered for several days. 100 Cycles Per Second (Hz) - At this level, a person experiences irritation, "mild nausea, giddiness, skin flushing, and body tingling." Following this, a person undergoes "vertigo, anxiety, extreme fatigue, throat pressure, and respiratory dysfunction." (Source; the Sonic Weapon of Vladimir Gavreau, by Gerry Vassilatos)

There are still a lot of theories about infrasound in question, but it is important that people and paranormal investigators in particular are aware of its existence and affects.

Physicists studying the effects of infrasound upon the human body have reported that volunteers participating in their experiments complain of weariness, high pressure in the eyes and in the ears, but never mention hallucinations or ghosts. More results from other studies revealed the following.

Infrasound Toxicological Summary, November 2001 - "When male volunteers were exposed to simulated industrial infrasound of 5 and 10 Hz and levels of 100 and 135 dB for 15 minutes, feelings of fatigue, apathy, and depression, pressure in the ears, loss of concentration, drowsiness, and vibration of internal organs were reported. In addition, effects were found in the central nervous system, the cardiovascular system, and the respiratory system. Synchronization phenomena were enhanced in the left hemisphere. Visual motor responses to stimuli were prolonged, and the strength of the effect was reduced. Heart rate was increased during the initial minutes of exposure. Heart muscle contraction strength was reduced. Respiration rate was significantly reduced after the first minute of exposure." (Sorry, I didn't note the source for this paragraph of information)

Human reactions to infrasound 20 Hz is considered the normal low frequency limit of human hearing. When pure sine waves are reproduced under ideal conditions and at very high volume, a human listener will be able to identify tones as low as 12 Hz. Below 10 Hz it is possible to perceive the single cycles of the sound, along with a sensation of pressure at the eardrums.

Infrasound has been known to cause feelings of awe or fear in humans. Since it is not consciously perceived, it can make people feel vaguely that supernatural events are taking place.

The Ghost in the Machine Research by Vic Tandy, a lecturer at Coventry University, suggested that the frequency 19 Hz was responsible for many ghost sightings. He was working late one night alone in a supposedly haunted laboratory at Warwick, when he felt very anxious and could detect a grey blob out of the corner of his eye. When he turned to face it, there was nothing.

The following day, he was working on his fencing foil, with the handle held in a vice. Although there was nothing touching it, the blade started to vibrate wildly. Further investigation led him to discover that the extraction fan was emitting a frequency of 18.98 Hz, very close to the resonant frequency of the eye (given as 18 Hz in NASA Technical Report 19770013810). This was why he saw a ghostly figure — it was an optical illusion caused by his eyeballs resonating. The room was exactly half a wavelength in length, and the desk was in the centrer, thus causing a standing wave which was detected by the foil.

Tandy investigated this phenomenon further and wrote a paper entitled The Ghost in the Machine. He carried out a number of investigations at various sites believed to be haunted, including the basement of the Tourist Information Bureau next to Coventry Cathedral and Edinburgh Castle.

Turf War

“Boys, boys, crazy boys, get cool boys!”

Much like the 1960’s musical, West Side Story, that told the story of division and played itself out like as a school yard turf war fight, it seems to me, that there is a lot of behind the scenes disputes going in the paranormal community too. Disputes that are creating a division that is not going to turn out good for anyone involved.

The two most prevalent gangs…I mean, teams, left standing before the public eye that are more openly opposing each other is The Ghost Adventurers (GAC) and the Ghost Hunters (for now I’ll leave Ghost Hunter International out of the mix) Both of these powerful forces have carved out a place for themselves with paranormal enthusiasts amongst the television viewing public. Both have become pop culture celebrities too. Both have their own very different from each other style of carrying out investigations, as well as beliefs on the topic of the paranormal. Both are also creating, separate of each other, an official paranormal database of existing or new (if you qualify to be a member) list of active paranormal teams. I think the original thought behind is this was to create for themselves a list of teams that are considered qualified and locally available a specific region that they can send cases to, and/or to have these regional team members pre-investigate for them. If an existing GAC or GH team within their own organization feels the need to call in the big guns, than that regional team contacts the GAC heads or GH heads. I would think this should create a nice database of information regarding cases, evidence, and leads of suspected haunted places. I’m not really sure what type or information exactly either of these organizations is gathering, much less what they are doing with that information. I know I would like to know, don’t you too? What kind of information are they gathering from the teams that sign up with their organizations? What are they doing with it? Does an official member’s database of investigating procedure, protocol, evidence or the like exist? Besides, what are they doing with all of their own evidence? Does it get passed along to science labs or the like for further evaluation? Who owns this information and evidence?

What disturbs me about these two power players is their need for exclusivity and division across the playing field, not just within the world of television either. I’ve stated before being a paranormal investigator or researcher is more of an industry now than ever before, but if this field is to progress and be taken seriously by all, not just paranormal enthusiast, there needs to be a coming together.  I still believe in the intent of both of these organizations, but I question where it is they will lead us to when all is said and done.

I love both these organizations and their figure heads in their own right for different reasons. However, as your everyday, common paranormal investigator and researcher, I find myself feeling the need to tread lightly and/or walk a fine line due to the fact that I haven’t chosen to align myself with one main popular group over the other. If I join one over the other it is likely that someone from the other camp that I haven’t joined up with is going to cross to the other side of the street if they see me coming…. Or more accurately, I will be the one forced to the other side of the street. These organizations are at root and key to the coming together of the common investigator/researcher.

I love both the west side and the east side. I think both of these organizations is sincere in their own personal pursuit of gaining knowledge into the paranormal, and believes what they are doing will advance the field of paranormal studies into a mainstream science. I am a fan of both shows.  I appreciate how they’ve brought the paranormal world to the forefront and to the attention of the general public. I also like that this attention is bringing money and development to the technological, engineering, and scientific side of paranormal exploration. However, I think they’ve both been sweep up by the media frenzy, and the executive producers, and advertising executives that have much to say about their television presence. I see it as good intensions gone awry. Sadly, the casualty of the west side/east side battle is going to be the sincere advancement of the paranormal field and widespread acceptance of the field within the scientific community and with the public. Now don’t get me wrong, there are many new brilliant minded faces now tackling the paranormal field because of them, but at what cost?

 Can’t we all just get along ...play nice…and work together towards a common goal? Ahhh, maybe I’m just too naive a person, and maybe the answer is, we can’t.
