Abstract: The subject of research into allegedly supernatural “Electronic Voice Phenomena” is considered in the light of both anecdotal reports and formal experimental studies of related aspects of human auditory perception. “Rorschach Audio” offers the primary hypothesis that an understanding of the relevant aspects of psychoacoustics provides a complete explanation for most EVP recordings; and a secondary hypothesis that an informed understanding of these processes is as relevant to the emergent field of sound art as studies of optical illusions have been to the study of visual art.

Polonius: “By the mass, and ’tis like a camel indeed.”
Hamlet: “Methinks it is like a weasel.”
Polonius: “It is backed like a weasel.”
Hamlet: “Or like a whale?”
Polonius: “Very like a whale.”

“Sometimes we see a cloud that’s dragonish;
A vapour sometime like a bear or lion,
A tower’d citadel, a pendant rock,
A forked mountain, or blue promontory
With trees upon’t, that nod unto the world,
And mock our eyes with air.”
Shakespeare “Antony and Cleopatra”

The title of this article is taken from a text written for the sleevenotes of a compact disc called “The Ghost Orchid”, subtitled “An Introduction to Electronic Voice Phenomena” [1]. For those who may be unaware, Electronic Voice Phenomena are a class of allegedly “mysterious” vocal recordings, and while several explanations have been offered to explain their origin, the overwhelming majority of EVP researchers believe that their recordings constitute physical evidence of contact with the afterlife. In other words EVP researchers mostly believe that it is possible, using various radio and electrical engineering techniques, to record the voices of ghosts.
Edison and Marconi both believed in the possibility that radio technology might enable contact with the afterlife – an idea that sits well within the context of Victorian enthusiasm for various forms of Spiritualism, however the EVP movement proper began in 1957 when Friedrich Jürgenson, an artist who had previously painted portraits of Pope Pius XII, found human voices intruding on recordings he had made of his own voice and then, in 1959, of birdsong. Convinced that these recordings represented communications from alien lifeforms and, for instance, his deceased mother, Jürgenson temporarily abandoned his artistic career to concentrate on these experiments and publicise his findings. In 1960 he started recording similar voices with radio equipment, and published the books “Rösterna Från Rymden” in 1964, “Sprechfunk Mit Verstorbenen” in 1967, and “Radio och Mikrofonkontakt med de Döda” in 1968. From 1968 onwards Jürgenson cemented an increasingly a close relationship with the Vatican, making a number of documentary films about religious themes, and executing portrait commissions for Pope Paul VI [2]. Jürgenson’s publications, and particularly the idea that he had amassed evidence proving the existence of an afterlife, attracted considerable attention. Konstantin Raudive took up the cause of EVP research, allegedly making tens of thousands of recordings. Through the publication of his book “Breakthrough” in 1971 [3] Raudive became the leading light in an international circle of EVP enthusiasts. Today the movement that Jürgenson and Raudive effectively founded has evolved into a widespread activity of such complexity that it would be foolhardy for any author to attempt a truly comprehensive survey. The purpose of this article is not to attempt that daunting task, but to address the major, salient issues which recur throughout EVP research and which in fact underpin the entire belief system.
This article will argue that EVP represents a classic example of a supposedly “strange” phenomenon for which there is a proverbial ‘perfectly rational explanation’, and, perhaps somewhat counterintuitively, also suggest that a critical discussion of EVP can be a rewarding and valuable exercise. This is because despite my initial scepticism and belief that exposing the central fallacy involved in EVP is little more than a statement of the obvious, I now believe that it can also be shown that EVP recordings evidence psychological phenomena that are inherently interesting and important. Similarly studying how this evidence has been turned into a complex, often entrenched belief system is of genuine anthropological interest, not least because the process entails the use of electronic technology to help construct, rationalise and validate a fundamentally anti-scientific belief system.
The material presented will also be used to support a secondary hypothesis – that an understanding of the processes involved in EVP may also contribute to theories of art criticism, both in general terms and with particular reference to music and sound art. It has to be said that the ideas on which these hypotheses are based are not innovative, that they are already embedded in mainstream critical theory, and that they trace direct descent from an individual generally recognised as the most important figure in the history of Western art. What is most surprising about these ideas is not their existence, but the extent to which they, like sound art in general, have previously been ignored. Many of the relevant psychological theories are not so much familiar to, but were in fact pioneered by art historians and critics (several of whom have been major contributors to Leonardo). However it still seems to be the case that ideas which were primarily developed to explain certain aspects of visual perception and enhance the appreciation of visual art also have great relevance to issues of acoustic perception – and this aspect of their interpretation seems to have received relatively scant attention. While a body of anecdotal and experimental evidence does exist connecting visual art theories to ideas about acoustic perception, to the best of my knowledge this material is dispersed and has neither been grouped together previously nor applied to practical issues such as assessing EVP and sound art. It should be admitted that this secondary hypothesis only became apparent after noticing a fairly serious mistake in the text of the “Ghost Orchid” sleevenotes, a mistake which we will return to later.
My first exposure to examples of Electronic Voice Phenomena was when as a teenager I heard a flexidisc of voices recorded by Konstantin Raudive published in 1982 by “The Unexplained” magazine [4]. The style of these recordings is typical of EVP – a narrator introduces contacts which manifest as brief bursts of distorted voice accompanied by very high levels of radio interference and what appears to be machine noise picked from the recording apparatus by a microphone. The examples are repeated several times and the ambience of the recordings is menacing. My initial reaction to hearing this material was one of sheer disbelief, since in addition to instinctive scepticism about any claims to the existence of the supernatural, outright forgery of such material would be absolute child’s play. The most primitive tape recording and overdubbing techniques could easily produce phenomena of this nature – not least because the more basic the technology used, the lower the signal to noise ratio, the more the finished product would resonate with an aura of menacing low-fidelity mystique which can even help impart a subjective impression of authenticity to such material. Put simply, if the voices recorded were of comparable quality to conventional studio recordings of speech, then nobody would have believed such rubbish for a minute – the fog of noise which degrades these signals still seduces some people into suspending disbelief. It seemed amazing that, in assuming shared faith in the alleged origin of these recordings, the disc’s publishers had the confidence to expect such a degree of gullibility on behalf of their audience. I will be perfectly frank in saying that the way in which this material was interpreted would be funny were it not so tragic. However I will also describe why I now believe that some EVP researchers, although misguided, may have genuine motives, and that many of the signals they have recorded are not consciously faked, but are instead commonplace material phenomena whose origin and nature they have misunderstood.
The hypothesis that EVP could be described as authentic phenomena, and that explanations exist to account for how they arise is drawn from a number of sources. The neurologist Oliver Sacks discusses the subject of acoustic projection in his book “Seeing Voices” [5], quoting descriptions of the so-called “eye music” and “phantasmal voices” experienced by the poet David Wright in his autobiographical work “Deafness” [6]. Having lost his sense of hearing in childhood, after the onset on spoken language, Wright found himself able to experience reconstructed sound-images projected by his mind into his perceived environment as an extension of visual cues. Lip-reading triggered actual voices inside Wright’s mind despite the fact that no environmental information was being provided by his ears. The projecting effect was so strong that Wright even reported hearing ghost-sounds conjured by the motion of trees in wind. Wright explained that “my deafness was made more difficult to perceive because from the very first my eyes had unconsciously begun to translate motion into sound. My mother spent most of the day beside me and I understood everything she said. Why not? Without knowing it I had been reading her mouth all my life. When she spoke I seemed to hear her voice. It was an illusion which persisted even after I knew it was an illusion. My father, my cousin, everyone I had known retained phantasmal voices. That they were imaginary, the projections of habit and memory, did not come home to me until I had left the hospital. One day I was talking with my cousin and he, in a moment of inspiration, covered his mouth with his hand as he spoke. Silence!” Wright’s experiences are extreme versions of a capacity for projection that not only manifests in all senses in most people, able-bodied or otherwise, but also underpins the whole process of perception. Sacks describes similar examples involving anosmia, blindness and the “ghost” or “phantom” limbs experienced by some amputees – the latter being the subject of fascinating research by Vilayanur Ramachandran, director of the Centre for Brain and Cognition at the University of California, San Diego [7].
David Wright’s faculties may sound extraordinary but Celia Woolf, a Research Speech and Language Therapist at the Department of Phonetics and Linguistics at University College, London, described experiments which suggest that lip-reading is an important part of normal speech perception. “The McGurk effect refers to the results of a study in which subjects were asked to watch video recordings of a face saying monosyllables, and report what they had heard. It was found that subjects’ perceptions were strongly influenced by the visual information provided by the face. So when the video was dubbed (the face says “ga” but the voice says “ba”) listeners reported hearing the syllable “da” which is acoustically midway between “ga” and “ba” [8][9].” The effect is that when the eyes are closed the sound heard is different from when they are open [10].
Among wartime experiences related in his autobiographical novel the “The Periodic Table” [11] Primo Levi recalled a laboratory test apparatus called a heterodyne which, under certain conditions, functioned as a radio receiver. He described an “intricate universe of mysterious messages, morse tickings, modulated hisses, deformed, mangled human voices which pronounced sentences in incomprehensible languages or in code… messages of death… the radiophonic Babel of war”, and it is perhaps not surprising that studies of this confused miasma of impulses also provide useful clues to help unravel the enigma of EVP. Olive Renier and Vladimir Rubinstein wrote in their book “Assigned to Listen” [12] that “the mechanism of projection plays a major part in hearing”. “Assigned to Listen” describes the “ether war” fought by BBC foreign-language radio monitors, who scanned the Second World War’s “remorseless sea of noises” for the broken voices, coded messages, news, propaganda, disinformation and entertainment broadcasts that fought for bandwidth with the incessant vagaries of ionospheric propagation and the turbulence of electrical and magnetic storms. BBC radio monitors recorded often weak impulses onto primitive Ediphone wax-cylinder “transcribers” (magnetic tape recorders were not introduced until the end of the WW2) degrading the quality of discernible intelligence to the point at which the problems encountered converge with issues familiar to photo-reconnaissance analysts and restorers of antique paintings. The necessity of re-analysing voice recordings over and over to detect faint traces of intelligence in a dense fog of noise is virtually identical to some EVP research techniques, but not surprisingly “Assigned to Listen” makes no mention of any monitor ever ascribing any signal to ghosts.
While stressing that “this crucial fact of Gestalt psychology is not easy to explain in words”, “Assigned to Listen” discusses ambiguities of acoustic perception in some detail. “Projection is the mechanism by which we read familiar shapes into clouds, or melodies into the monotonous rattle of a train. In a similar way we can read speech into a medley of noises. Leonardo da Vinci advised young painters to practice their imagination by looking at cracked walls and reading fantastic scenes into strange patches.” Similarly Celia Woolf describes an experiment which indicates that “some listeners perceive time varying sinusoidal tones as speech, with some listeners even reporting the sentence they had ‘heard’ [13].” “Assigned to Listen” asserts that “perception is there so that we should know when to stop projecting… a configuration of sounds evokes some vague association of words and we start projecting them into the medley. Then we shall either find that there are other sounds which stand in the way of this projection or we shall be happy until we pass to larger contexts… if then the sense does not fit we must… start introducing some auxiliary hypothesis to save our projection from being confuted by the remaining signposts of sound.”
An important lesson of the Evesham listening experience was that monitors should not be too dogmatic about “saving” a troublesome interpretation. They should instead recognise the long-term importance of admitting failure when necessary and discarding incorrect hypotheses, even if much effort had been invested in their formation. If a monitor thought he or she had finally made sense of an utterance swathed in noise, only to find its apparent meaning contradicted by the sounds that followed, they should not try and force a square peg into a round hole out of sheer frustration. They should instead relax, staying true to the axiom that tiny bursts of information are inherently easier to misinterpret than large ones, and trust that their inability to interpret a larger sense indicated the initial hypothesis had been wrong. They should instead formulate a new hypothesis, and test this until it was either discarded or proven – “the whole comes before the part”. “Rather than pressing the data of sound into our pet projection, we must discard the projection and start again.”
Similarly audiologists sometimes advise those who begin to experience conversational problems owing to partial deafness not to concentrate too hard on hearing individual words, but instead to relax and interpret the overall flow rather than the component detail of conversational speech. Evidently concentrating too hard on the minutiæ of unclear sentences can effectively make deafness worse, with psychological stress factors exacerbating what were originally only physical problems. These experiences tend to support the contention of Michael Handel, a historian of military intelligence and deception, that “another piece of advice… based on psychological tests, is not to put too much confidence in conclusions drawn from a very small body of consistent data… because conclusions drawn from very small samples are highly unreliable” [14]. “Assigned to Listen” states that “six or ten syllables may answer to all sorts of projections, but thirty or forty are less likely to trick you” – typical EVP recordings often involve no more than three or four. Handel’s advice concurs with the basic principles of statistics and experimental science. Handel also quotes Richards Heuer that “as a general rule, we are more often on the side of being too wedded to our established views and thus too quick to reject information that does not fit these views, than on the side of being too quick to reverse our beliefs. Thus, most of us would do well to be more open to evidence and ideas which are at variance with our preconceptions [15].”
In a 1996 “Scientific American” article [16] Shawn Carlson described an experiment designed by Diana Deutsch, a professor at the University of California, San Diego. Deutsch’s experiment demonstrates how acoustic projections can be explored in controlled conditions [17]. Deutsch recorded the sound of a person speaking two neutral words, and created a sequence in which the voice samples are reproduced in alternating stereo channels. Played back over stereo loudspeakers at “dizzying” speeds, fast enough that the sounds remain recognisable voices while scrambling semantic content, the sequence produces what Carlson described as “a pattern that sounds like language, but the words are not quite recognisable”. Carlson continues “within a few seconds of listening to this strange cacophony, my brain started imposing a shifting order over the chaos as I began hearing distinct words and phrases. First came ‘blank, blank, blank’. Then ‘time, time time’. Then ‘no time’, ‘long pine’ and ‘any time’. I was then astonished to hear a man’s voice spilling out of the right speaker only. In a distinct Australian accent it said “take me, take me, take me”.” The ink-blot test invented by Swiss psychiatrist Hermann Rorschach springs to mind, and it is interesting to note that the single Rorschach projection described by Henry Gleitman [18] involves not only projections of “a head blowing smoke”, but also a “ghost” and an “angel” – the last two being themes that strongly resemble the emotional agenda that underpins many examples of EVP. In my own experience it proved necessary to listen to Diana Deutsch’s recording many times before words began to emerge with crystal clarity, but when subjectively ‘real’ sounding voices did start to form the experience was striking and the illusions were sometimes very clear indeed. Deutsch’s recording resembles the voice manipulation experiments of the sound artist Saul Z’ev, and Naeser and Lilly’s “Repeating Word Effect” [19].
To my amazement it transpired that identical techniques to those devised by Diana Deutsch are established methods for eliciting EVP – known as “Speech Synthesis” – “a phenomenon which…” EVP researcher Raymond Cass claimed “at the present time completely evades physical explanation [20]”. It could be argued that EVP experimenters are in a sense psychologists who have misunderstood their own work, however while it seems clear that many EVP researchers are inadvertently reproducing acoustic projection experiments, it cannot conversely be argued that the Deutsch illusion inadvertently reproduces EVP. The diverse and evolving meanings projected into the unvarying source material of Deutsch’s illusion by even single subjects demonstrates that this phenomenon is endogenous, that it comes from inside the subject, and subjective. Conversely the pre-emptive narration characteristic of EVP demonstration recordings creates a shared illusion of entirely false exogeny, the sense that the meaning comes from outside listeners’ imaginations, and hence an illusion of objectivity. The widespread use of conventional pre-recorded audio in EVP speech synthesis firmly establishes the subjective origin of the imputed meanings. This argument could be countered by pointing to the observation of shared meanings attributed to specific EVP, however “Assigned to Listen” contends that “projections have a way of sticking to sound… it isn’t easy once you hear your train rattling Carmen to make it change to the Blue Danube”, and the process by which EVP experimenters create this illusory objectivity is a subject we will return to shortly. To be fair some EVP researchers are aware of the phenomenon of acoustic projection [21] and use jumping lock-groove vinyl records, looped magnetic tapes and computer audio samples, static and other sources of repetitive, pseudo-random noise as raw material for inducing projections. What seems absent from their discussions of these techniques is any suggestion that projection effects might be responsible not only for EVP created in these ways, but in fact for ALL manifestations of EVP.
To place these lessons in the context of broadcast EVP, signals from across the entire radio spectrum have a tendency to drift away from their original broadcast frequencies and to spontaneously demodulate onto amplifying circuits, as all audio amplifiers and gain stages in radio circuits can function as broadband Very Low Frequency receivers. Microphone cables often function as VLF antennas, especially when unshielded and used out-doors, with the amplifiers they are attached to functioning as VLF radios. Taxi transmissions, emergency services, airband, maritime, military, short, medium and long-wave commercial broadcasts, TV voice channels, radio ham experiments, CB radio, bugging devices, conferencing systems, intercoms, baby intercom / alarms and analogue mobile phones share a tendency to emerge in the same VLF waveband, frequently producing stray signals. These signals are well known to PA operators, people who install in-car entertainment and wildlife recording engineers, who employ an arsenal of electromagnetic shielding devices to eliminate this interference – Faraday cages, electrically-conductive tents, paints, co-axial cables, earth-lines, grounding etc, and the radio frequency “chokes” or line-filters installed in PAs, car stereos and VLF natural-phenomena receivers. When stray signals are heard they are often very garbled, and therefore ideal raw material for acoustic projection. Some EVP researchers have attempted to exclude interference using metal Faraday cages, which surround their experimental apparatus, draining the external electromagnetic field into the earth. However most EVP techniques require not the removal, but the addition of extraneous noise to the basic input in order to improve the success and clarity of recordings. Radio static, deliberately mis-tuned voice transmissions (especially in languages not understood by the researchers), audio oscillators, microphone feedback and tape recordings of foreign-language courses, birdsong, fountains, hissing taps, rain, surf and wind are all used. Deliberately adding noise to improve EVP reception may seem counterintuitive, but it makes perfect sense in the light of previous observations. Investigator Raymond Cass states, amongst other wilder hypotheses, that EVP voices “may be a mutant development of some remote corner of the subconscious mind, or a transient by-product of the electromagnetic pollution which now rings our planet”, implying that these explanations are mutually-exclusive. My belief is that both interpretations are simultaneously true, but that the mental process responsible is really not that remote.
A typical EVP process involves prompting the imagination by asking questions of deceased ‘entities’ out loud – in the manner of a Spiritualist séance, recording, and then repeatedly analysing any signals that have emerged. Researchers allege the presence of polyglot voices, which switch languages from one word to the next, and enthusiasts evidently scour foreign dictionaries for meanings that concur with the rhythms of recorded sequences. EVP researchers maintain that the hypothetical ghosts invent neologisms and take liberties with grammar – in other words we are asked to accept that entities which have the intellect to acquire a grasp of many languages have lost the ability to speak grammatically or confine themselves to proper words. These interpretive techniques set the widest possible parameters for the subjective attribution of meaning, thereby validating and accumulating ‘data’ which would otherwise be disregarded as meaningless. By asking questions of the spirit world researchers tell themselves and other listeners how to interpret sounds before any signals manifest, heavily influencing subsequent analyses. When compiling EVP demonstration recordings the convention is to reinforce this process by announcing meanings before replaying examples, rendering the material useless for objective analysis (note that similar prompts existed on the cassettes from which “The Ghost Orchid” CD was compiled, but, even though most were removed at the CD mastering stage, the prompts survive in the form of track titles).
George Miller described an experiment that demonstrates the strength of this prompting effect. “David Bruce recorded a set of ordinary sentences and played them in the presence of noise so intense that the voice was just audible but not intelligible. He told his listeners that these were sentences on some general topic – sports, say – and asked them to repeat what they had heard. He then told them that they would hear more sentences on a different topic, which they were also to repeat. This was done several times. Each time the listeners repeated sentences appropriate to the topic announced in advance. When at the end of the experiment Bruce told them that they had heard the same recording every time – all he had changed was the topic they were given – most listeners were unable to believe it [22][23].” The process of prompting has interesting parallels with the misdirection techniques employed by card sharps, stage conjurers, pickpockets, magicians, ventriloquists and military strategists, some of which involve ingenious uses of sounds (although the most effective misdirection technique employed by conjurors is, of course, the presence of the “glamorous assistant”).
Interpreting this evidence en masse, the implication is that rather than their being anomalous, occasional events, we are unconscious of the extent to which projections take place continuously, as an inherent part of normal cognitive processing. For instance it is well-known how difficult it is to spot errors of detail when one is familiar with the overall sense and structure of a text. Novice readers spell-out individual letters before interpreting a written word, while the eyes of experienced readers glide over text in high-speed saccadic jumps. The degree of familiarity that comes from having written a particular text oneself makes it almost impossible for authors to switch-off the projecting mechanism and detect small errors isolated in text of their own composition – hence the necessity for proof-reading as a separate profession to authorship. Similarly in acoustic cognition we actively project sense, interpreting data as conglomerate chunks of meaning according to reflexive pattern-recognition techniques which skip from point to point, ignoring some detail in favour of fuzzier, more cost-effective mental stratagies. Normally projections generate interpretations which concur with the spectrum of inputs from vision, taste, touch, smell and memory. Therefore we are only aware of the process of projection and especially its imaginary, subjective aspect when it occasionally generates images which disagree with the broader context – errors which we perceive as perceptual illusions.
This theory traces its origin back to Hermann Helmholtz’s “Treatise on Physiological Optics” of 1866, as discussed by Richard Gregory [24]. Helmholtz categorised perceptions as unconscious inductive inferences which, despite heavy reliance on memory as well as direct sensation “come about with immutable certainty, lightning speed and without the slightest meditation”. Gregory traces the evolution of these ideas to the discovery of the Camera Obscura, and the concomitant realisation that the images that the brain perceives are not the same as the sensations received by the eyes. An important precursor to Helmholtz ’s ideas can be found in the text of the engraver William Hogarth’s book “The Analysis of Beauty” published in 1753 (which was the subject of an installation in the “Noise” exhibition at Kettle’s Yard, Cambridge UK, 2000). Hogarth wrote that “Experience teaches us that the eye may be subdued and forced into forming and disposing of objects even quite contrary to what it would naturally see them, by the prejudgment of the mind from the better authority of feeling, or some other persuasive motive. But surely this extraordinary perversion ofthe sight would not have been suffr’d, did it not tend to great and necessary purposes, in rectifying some deficiencies which it would otherwise be subject to (tho’ we must own at the same time, that the mind itself may be so imposed upon as to make the eye see falsely as well as truly) for example, were it not for the controul over the sight, it is well known, that we should not only see things double, but upside down, as they are painted upon the retina, and as each eye has distinct sight [25].”
This capacity for projection reaches its ultimate æsthetic realisation in the anamorphoses of Salvador Dalí – his “Paranoic Visage – the Postcard Transformed”, the “Head of a Woman in the Form of a Battle”, the particularly eerie “Metamorphosis of Hitler’s Face into a Moonlit Landscape” and “Portrait of my Dead Brother” [26]. The similarities between these last two paintings and themes in many EVP recordings do not seem accidental, since they are all representations of personalities that typically haunt the unconscious mind. Jürgenson and Raudive believed they had recorded deceased relatives, and Raudive also Adolf Hitler. Raymond Cass recorded the what he believed to be the voice of Heinrich Himmler, and EVP recordings are littered with alleged contacts with deceased friends, relatives, important historical figures and menacing apparitions of evil personalities whose memories linger in the human imagination. Salvador Dalí was quite rightly kicked out of the Surrealist movement because of his obsession with Adolf Hitler, despite the fact that he was being true to at least one set of Surrealist imperatives – the preoccupation with the murmurings of the subconscious mind. A common aspect of EVP listening is the impression that when first encountered (often accidentally, as a result of tape recording experiments) stray voices are interpreted as speaking directly to the person who recorded them. The great Surrealist film-maker Jean Cocteau exploited this in “Orphée”, suggesting that coded radio messages “inspired by the BBC broadcasts of the occupation” were messages from the spirit world. Orpheus asks Heurtebise “Where could they be coming from? No other station broadcasts them. I feel certain they are addressed to me personally [27].”
Writing in Fortean Times magazine Jürgen Heinzerling described EVP as “more complex perhaps than even the contradictory abyss that is ufology” [28] and speaks of “field research often hampered by a remarkable lack of critical judgement”. I freely admit that my opinion of EVP is deeply negatively prejudiced. However, since Heinzerling rightly argues that the scientific community’s ignorance of EVP “indirectly supports the spreading of this cult, as potential followers are confronted with convincing demonstrations that are only ‘explained’ by the quasi-religious musings of the convinced cultists”, what I hope to add to this debate is evidence from outside its own hermetic environment which places EVP in the context of viable explanatory material. My explanatory model posits the evolution of a positive feedback loop in which primordial superstitions about the afterlife are sufficiently powerful to actively create EVP, and so created, EVP recordings are recycled as evidence of a factual basis on which the belief-system feeds and grows. As a form of psychological test consistent with a concept of “Rorschach Audio”, EVP recordings not only reveal something of the role that emotional factors can play in shaping perceptions, and of the psychology of their individual “creators”, but EVP as a belief-system reveals something of the way in which people construct, authenticate and share beliefs, and the way in which social groups gather around ideas. Mental health issues associated with EVP, and the subject of how public ignorance of scientific psychology has been manipulated by fraudulent psychic researchers, and, with respect to related “back-masking” phenomena in rock music also by Heavy Metal groups and right-wing Christian activists, are beyond the scope of this text.
The advice offered to the Evesham monitors, that they should formulate, test, and then either accept, refine or discard projected interpretations is similar to ideas formulated by the philosopher Karl Popper [29]. Popper propounded the usefulness not of absolute scientific truths (whose fragile, idealised perfection carries with it stylistic echoes of earlier, more primitive beliefs) but of self-refining feedback loops in which “working hypotheses” are progressively formulated, tested, and either discarded or accepted according to the rules of experimental evidence. Incidentally Popper’s ideas seem to have been the same working principles as were embedded in the circuits of the Colossus machines designed by the mathematician Alan Turing to decipher the Enigma codes of WW2. In the recent TV dramatisation of his life the Turing character spoke of building a “machine which senses contradiction”, of how “contradiction implies the solution” and of “electricity…” that “…flows through the hypotheses”, in a brief but beautiful description of this interface between philosophy and electrical engineering. According to Turing’s biographer Andrew Hodges [30] the Enigma code-breaking process “depended on the flow of logical implications from a false hypothesis” – a concept which has interesting parallels with the recommendations described in “Assigned to Listen”. Since important philosophical ideas are not necessarily either complex or obscure, and since they can be embedded in abstract automata as well as real-world engineering designs, this digression suggests that such ideas can just as easily be embedded in sound art. Lessons about scientific methodology can be, if not learned, then reverse-engineered by taking a critical interest in styles of pseudo-scientific thought. In this case the entire EVP belief system is a macroscopic false hypothesis condensed from a larger body of microscopic false hypotheses. Scientific method itself can be regarded as depending on a flow of logical implications from the history of false hypotheses.
This argument highlights the importance of openly admitting to ‘honest’ mistake – indeed this article echoes this point, because much of its content was inspired by just such a mistake. When compiling the material for the original “Ghost Orchid” sleevenotes I attributed advice about psychological projection to authors Olive Renier and Vladimir Rubinstein, who were BBC monitors in WW2. The advice was quoted from a paper entitled “Some Axioms, Musings and Hints on Hearing” written by their Monitoring Supervisor – Ernst Gombrich. It was only on discovering this mistake that I realised the extent to which investigating this subject could provide also tools for analysing sound art.
Psychological projection is discussed in detail in Ernst Gombrich’s classic “Art and Illusion” [31], in which Gombrich also mentions his acquaintance with Karl Popper in Vienna before WW2. Gombrich cites Leonardo da Vinci’s famous advice to novice painters, which is particularly interesting because of its final sentence. “You should look at certain walls stained with damp, or at stones of uneven colour. If you have to invent some backgrounds you will be able to see in these the likeness of divine landscapes, adorned with mountains, ruins, rocks, woods, plains, hills and valleys in great variety: and then again you will see there battles and strange figures in violent action, expressions of faces and clothes and an infinity of things which you will be able to reduce to their complete and proper forms. In such walls the same thing happens as in the sound of bells, in whose stroke you may find every named word you can imagine.” While Diana Deutsch points out that “Leonardo may have been particularly susceptible to such transformations” because “perhaps this facility is associated with extreme creativity?” [32] the phenomena Leonardo described are acoustic projections closely related to Deutsch’s own experiments and to EVP. What is most surprising is that while the influence of Leonardo’s advice with respect to figurative and abstract painting is probably inestimable, from the point of view of fine-art practice his final sentence seems to have been almost totally ignored.
The psychologist Georgy Kepes characterised perception as an active, inherently creative process [33]; and I draw this article towards its conclusion by stating my agreement with what I believe is an idea both developed and shared by Helmholtz, Gombrich, Gregory and others, that at a fundamental neurological level many of the faculties exercised in basic forms of perception, in the formulation of scientific hypotheses, and in the appreciation of art have a great deal in common. There is much we can usefully learn from improving our knowledge of, and much we can usefully achieve by promoting understanding of these processes. With respect to the role that projection plays in the appreciation of art, while one must acknowledge that this is sometimes taken to ridiculous extremes, nonetheless the process of reading “meanings” into artworks is simply an extension of processes which are hard-wired into everyone’s perceptual mechanisms anyway. Exercising this faculty is the essence of artistic appreciation, as well as the essence of appreciating sound art. Finally, if the style and content of this article seem a harsh appraisal of phenomena whose creative impetus we know full well stems from an instinct that we all share – the desire to triumph over the tragedy of human mortality and to retain contact with lost friends – then I would like to suggest that the fundamental message of any statement which undermines belief in life-after-death remains, as always, the same; it is the most romantic notion that mankind has ever conceived – seize the day.
“Rorschach Audio” is dedicated to Geoffrey Grigson – 1905 to 1985 – poet, naturalist & ether warrior

Hello. Last week I’ve read very interesting article about psychological consequences of modern war especially the Afgan war. If anybody is interested the article is published here: http://pakobserver.net/detailnews.asp?id=164761. Goodbye
You made several nice points there. I did a search on the matter and found most folks will agree with your blog.
Hi, just wanted to tell you, I enjoyed this article. It was helpful.
Keep on posting!
I enjoyed certain aspects of this article – however the ” I freely admit that my opinion of EVP is deeply negatively prejudiced ” Say’s it all really .
Thanks for the comment and thanks for reading, but. no, it most definitely doesn’t say it “all” – there’s alot more. The other elements it’s important to consider are not just the (honest statements about the) attitude but the factual evidence that’s presented in this article 😉
I am a paranormal researcher & feel it is my duty to research every aspect of my chosen subject that i can. I found your article informative and interesting but I just wish – as truthful as you are that you where not ” deeply Negatively Prejudiced ” because the then so called Factual evidence just becomes a compilation of Data and Research which you have compiled and used to back up your own prejudiced view’s with reference to the subject matter in question . I would be very interested in what actually triggered such deep negative prejudice in the first instance ?
It’s great you found the article informative, rest assured there’s nothing “so called” about any of the evidence presented however (in the article, on the website, or in the book). All research is selective – this project no more so than EVP research, and the simple act of forming any hypothesis biases all research. Unlike most EVP research, this project places its’ prejudices and preconceptions in plain sight, and (as you know if you’ve read the article) honestly reports when (as they occasionally have been) they were contradicted by becoming better informed about EVP; and, finally, to answer your question directly, what triggered the prejudice was a simple belief that, whether we like it or not, it’s very unlikely ghosts exist.
Informative article, totally what I was looking for.
