Classic Signs Of Hauntings Researched!

* Research into a supposed haunting has revealed that all the classic signs of ghosts can be explained as the result of very low frequency sound waves trapped inside buildings.
Capable of being triggered by nothing more than the wind passing over walls, the sound waves cannot be heard. But scientific tests have revealed that they have effects on the human body that can account for the wraith-like appearance of ghosts and even the feelings of cold and terror that accompany them.
The explanation emerged after a chance discovery by a university academic who found himself personally involved in a haunting, late one night in the laboratory of a medical manufacturing company based in the Midlands.
Vic Tandy, an expert in computer-assisted learning at Coventry University, had been told that the building was haunted, but dismissed it as a joke. He changed his mind after the events that unfolded one night as he worked alone in the office.
"As I sat at the same desk writing, I began to feel increasingly uncomfortable," he said. "I was sweating but cold and the feeling of depression was noticeable - but there was also something else. It was as though something was in the room with me.
"Then I became aware that I was being watched, and a figure slowly emerged to my left. It was indistinct and on the periphery of my vision, but it moved just as I would expect a person to. It was grey, and made no sound. The hair was standing up on the back of my neck - I was terrified."
Mr Tandy plucked up courage to look at the apparition face-on - only to see it fade and then vanish. "I decided I must be cracking up, and went home," he said.
The explanation emerged the following morning. Mr Tandy, a fencing enthusiast, was modifying one of his foils and had left the blade clamped in a vice while he went in search of oil. He said: "When I returned, I noticed that the free end of the blade was frantically vibrating up and down." Mr Tandy, a trained engineer, realised that the blade might be receiving energy from very low frequency sound waves filling the laboratory - so low that they could not be heard.
Tests duly revealed the existence of a "standing wave" trapped in the laboratory, which reached a peak in intensity next to Mr Tandy's desk. "It turned out to be caused by a new extraction fan, which was making the air vibrate at about 19 cycles per second," Mr Tandy said. "When the fan's mounting was altered, the ghost left with the standing wave."
Working with Dr Tony Lawrence of the university's school of health, Mr Tandy has now discovered the significance of this rate of vibration. In research published in the latest issue of the Journal of Society for Psychical Research, they reveal that "infra-sound" around this frequency has been linked to a whole host of physiological effects - including breathlessness, shivering and feelings of fear.
Most significantly, research by Nasa, the American space agency, has shown that the human eyeball has a resonant frequency of 18 cycles a second, at which it starts to vibrate in sympathy to infra-sound. "This would cause a serious smearing of vision," Dr Lawrence said.
While acoustic experts have known about the health effects of infra-sound for many years, until now no one has made the link to ghosts. Mr Tandy said that he has since come across two more "hauntings" where low-frequency sound may be to blame. He said: "One occurred in a corridor of a building that had a wind tunnel in the basement, and it was operating at the time of the sighting."
He said, however, that the wind blowing over a window in a side wall of a long corridor might be enough to create a standing wave, similar to that formed by blowing over the neck of a bottle. "It would be interesting to look at reports of haunted houses, to see if the 'ghosts' tend to appear in long, windy corridors," he said.
The discovery of the infra-sound effect is already creating a stir among experts in paranormal phenomena. Professor David Fontana of the University of Cardiff, a former president of the Society of Psychical Research, said: "It is very interesting, as it gives us another scientific variable we can fit into the picture."
Professor Fontana said, however, that infra-sound was unlikely to be the final answer. "It cannot explain those cases where there is some interaction between the person and the apparition - as there is with poltergeists for example," he said. "The problem is that whenever you get a potential explanation like this, you find that there are a whole lot of things it cannot account for."
