Yes, it looks at the wave function of sounds of various materials being 'rapped' or 'tapped' upon. Rapping is defined as a single strike to a surface by another object. It shows that with every case observed, the sound wave function starts at its highest amplitude, and gradually becomes lower. They then observed rapping sounds reported at several sites in which poltergeists were reported, as rapping is a common 'symptom' of these areas. They then recorded the rapping which is done here. Again, the sound is a single strike to a surface by another object, the only difference in the case of the poltergeist sites is that the objects being struck are a mystery. In all of these sounds, the rapping sounds' amplitudes started low, worked their way up to highest amplitude, and then lowered again. This goes against the findings of every other preliminary wave recording. The only other wave they'd found which followed this pattern, as far as noise goes, is caused by seismic activity. The study does not draw any final conclusions on this. It may be seismic activity at the poltergeist sites, but why so quietly, why only in those homes and not in others, and why so frequently, with no seeming correlation to fault lines? It was done quite well, in my opinion, and described perfectly well so it may be replicated by anyone with access to a reported poltergeist site.
Thanks tendo - you've raised yourself well above the average paranormal supporter by doing that! I salute you..

I have had a preliminary look at that pdf, and I have a very big problem with the words in bold - which is pretty much what the entire thing revolves around. I agree that it *looks* like they know what they are doing

, but I think there are some major issues and some huge 'leaps of faith' in that report. I also note that the references are pretty well completely devoid of any real acoustics-analysis content from credible sources and the author claims no degree/doctorate or similar in acoustics.. Plus the report has not been peer reviewed by (or published in) any credible
acoustics-related journal - instead it appears only in the 'Society of Psychical Research' - not exactly a high impact journal... The problem is, the entire report is based on a premise of acoustic waveform analysis and yet it has been published at one of a multitude of similar self-publishing societies in a field that has no relevant expertise.. and one that is known to publish pretty much anything sent to them, and could just possibly be seen as having a bias..
I'd also make the following casual observation - that report is INCREDIBLY wordy, given what should be relatively simple content.. That's not a good sign - sometimes people do that deliberately to make it seem comprehensive and also make it less easy to critique. However, until I have time to go thru it properly, I'll have to leave it at that.
Right now I am engaged on other things relating to imaging analysis, but once I get that one finished I will try to find some time to look at this report in more detail.
Sorry to be a naysayer, but I don't think you have found the holy grail.. But I will be back to go into it a bit more deeply.
Again, I applaud you for your considered approach though, so keep it up!
