Vic Tandy, a computer expert, experienced what he believed to be a ghostly encounter in a supposedly haunted lab in Warwick, England. Upon further investigation, he discovered that infrasound waves, specifically at 18.9 Hz, were causing vibrations that distorted his vision, leading to the apparition he thought he saw. Tandy's findings were later confirmed in another haunted location, where similar infrasound levels were detected. The discussion also touched on the effects of infrasound on humans, with participants exploring its potential psychological impacts and the challenges of creating low-frequency sound sources for experimentation. Overall, Tandy's work suggests that many ghost sightings could be explained by infrasound rather than supernatural phenomena.

This is just plain uncharitable and mean.

Tandy is a guy with a very intersting theory. He knows enough about accoustics to explain his reasoning, but he is not an expert in acoustics. He has not conducted and published a formal scientific study of this phenoenon. This is a side thing to his real profession that happened to get a lot of press. Nature, Science, and Physics Today would not jump to solicite material from a non-expert with an interesting theory about a subject like "hauntings" despite having no particular objections to it, now would they?

For the record I will clearly state that I do not think the kind of "haunting" experience Tandy experienced and described has anything to do with the "haunting" you and Tsunami experienced. Your experience was signifigantly different by virtue of the olfactory element, and the sensation of weight on the foot of the bed, to name two things that have never been proposed as a part of the infrasound kind of "haunting".

I say that in case you, Tsunami, and Evo are thinking I'm interested in Tandy in an attempt to explain your experience "away", which I'm not. Honest to God, I have no leads to what happened to you beyond the hoax by building caretaker possibility I speculated about.

Edited to add: to the extent that Tandy could explain what had happened to people like the very upset cleaning lady who was quite frightened by her experience, and anyone else who has been caught unawares by an infrasound "ghost' in a creepy place, he is doing a good thing. Shut the fan off: ghost disappears; an illusion. No worries. Why should people suffer anxiety over something stupid like a wobbling fan?

I don't think so. In science we require something called peer review. He has published his work. It only appears in one journal put out by the Psychical Research Society. This along with the weakness of his claims pretty much settles this for me for now. Perhaps one day he or others will gather enough supporting evidence to justify his claims. In the mean time it seems that he is selling books and soon, ghost machines. Hmmm.

I think so. Your "...unless it is not worthy of publication..." line is pure editorial on your part, and is intended to create the impression this is the only possible reason he hasn't been written about in those magazines.

I don't see where Tandy has tried to resist any peer review.

So, he has submitted a piece to a journal he felt would be interested. They published it, and...where's the problem?

"The weakness of his claims..." again, is you editorializing. They don't look weak to me at all. I think he has made an excellent case. You yourself were impressed enough to be in the process of making your own infrasound generator when this thread began.

It was intended to convey my take on the evidence presented. The more I learn and think about this the more dubious I am of his claim. I wasn't trying to be subtle.

Mainstream journals are the proper channel for publishing a theory; not the internet, books, and fringe journals. Since I have seen none mentioned, I must assume that either he avoids a qualified review of his claims, he awaits publication while his work is reviewed, or he can't get published because his claims lack sufficient supporting evidence. Similar public maneuvers by two gents named Ponds and Fleishmann led to the cold fusion fiasco of the late 80's. They were so discredited by this breach of protocol that they effectively went into hiding. The same rules apply to Hawking, Tandy, me, and anyone else who makes public claims such as Tandy's. Is this science or not?

Even you agreed that his unique 18.9 Hz dependency for eye resonance seems to fail. Since this was his key test for apparitions - specifically at 18.9 Hz - his most basic claim falls apart. Also, I don't think I am being mean spirited just because we don't agree. I am highly dubious about this whole business by Tandy. I am still allowing that eventually he might prevail but for the moment I just don't see it. As I said from the start, the wave intensities required for the desired effects appear to far exceed levels that would otherwise go unnoticed; even as infrasound.

This is where you are being uncharitable. As I tried to point out before, he is just a guy with an interesting theory which is well outside his own actual profession. He has a certain amount of evidence to show, but he has not conducted a formal study that he could write up nd present to any hard science journals. He presents nothing at the level of a "claim". What he has could be called a "theory" at the very best.

"Infrasound + spooky place = "haunting" is a notion that is almost certainly of so little interest to mainstream science that the reaction is not that it lacks credibiity, but that it evokes a response of "Could be, I suppose. So what?"

Infrasound, from the nature of the studies presented, is of interest to people concerned with occupaional safety. These people have no interest in whether or not it might have this pseudo-paranormal effect in old dungeons. The only people who have any real concern are paranormal believers and skeptics.

I am not aware if he has submitted anything to any hard science journals and been rejected but if he's has I would say it is either because he didn't conduct a formal study under specific conditions that people could recreate and test, or, it was because none of them deemed the subject to be particularly important.
Similar public maneuvers by two gents named Ponds and Fleishmann led to the cold fusion fiasco of the late 80's. They were so discredited by this breach of protocol that they effectively went into hiding.
The cold fusion guys were not discredited because they did not publish in the proper journals, Ivan. They did go through the peer review process and were discredited because no one could replicate their results. Someone who tried, who had read their material, figured out the mistake they had made. Breach of protocol was not the offense that discredited them, it was the fact their claims were plain wrong.

Cold fusion, also, was important.
Even you agreed that his unique 18.9 Hz dependency for eye resonance seems to fail. Since this was his key test for apparitions - specifically at 18.9 Hz - his most basic claim falls apart.

First off the 18.9 hz did not fail. He discovered that frequency in his workshop. Apparently it works, according to what he read in the NASA paper. The difference is that the other papers for which we found abstracts and from which we have second hand quotes, maintain that the eyes can be affected by many frequencies in the infrasonic range. This doesn't debunk Tandy at all. It increases the range of infrasound at which his theory might be accurate.
Also, I don't think I am being mean spirited just because we don't agree.
I don't either. Normally you are charitable in all disagreements with me and others. I found that one post to be an exception.
I am highly dubious about this whole business by Tandy. I am still allowing that eventually he might prevail but for the moment I just don't see it. As I said from the start, the wave intensities required for the desired effects appear to far exceed levels that would otherwise go unnoticed; even as infrasound.
Your impression of the wave intensities required come from the abstracts and brief quotes from papers none of us has read. The studies seem to disagree with each other (par for the course), and I suspect this is due to the fact that each was conducted under different circumstances for very different reasons and motivations. None studied the effects of infrasound as produced by improperly mounted industrial exhaust fans in shops of the size and construction in which Tandy had his experience.

I'm afriad you're right--but even worse, what's the chance of getting 'funded' if you even mention 'ghosts' or 'UFOs'...

One of my favorite 'science' stories is about the 'French Academy of Science' declaring 'rocks don't fall from the sky'---
