    This was recently published in the Society for Psychical Research and compares recordings of apparent poltergeist knocking to that of those of definite human origin. The results seem to be pretty interesting.
    Paranormal rappings associated with apparent poltergeist activity have been described for many hundreds of years. It is only now that an interesting pattern has been discovered within the fine detail of the paranormal rapping sounds. No explanation can be found for this pattern at present.

    The current edition of the Journal of the Society for Psychical Research (SPR), a learned publication dating back to 1882, carries an article by scientist Dr Barrie Colvin B.Sc., Ph.D., showing instrumental evidence for an inexplicable and objective banging sound detected in recordings made during alleged poltergeist activity.

    Whereas raps and knocking sounds produced by ordinary means exhibit a normal acoustic pattern, those recorded in alleged poltergeist cases show quite a different sound signature.

    Dr Colvin has analysed recordings of alleged poltergeist knocking obtained from around the world over a 40-year period. The earliest was a recording made by a local physician at Sauchie (Scotland) in 1960 and the most recent was obtained from a poltergeist case at Euston Square, London in 2000.

    Whilst the two types of rap sound rather similar, they are actually acoustically different, although the effect is only made apparent when the recordings of raps are submitted to detailed analysis.

    The sample involved 10 separate recordings recorded on different recording apparatus.

    In each of the recordings, when subjected to acoustic analysis, a particular sound pattern is detected which so far remains unexplained. Attempts to replicate this pattern in ordinary ways have so far been unsuccessful.

    The essential difference between these raps and those produced by normal means lies in the details of their sound envelope.
