Clairaudience

Clairaudience surfaces in the same nineteenth-century milieu as clairvoyance, coined by French mesmerists to describe entranced subjects who reported hearing rather than seeing at a distance, and adopted wholesale by spiritualism after 1848 as one of the standard modes by which a medium claimed contact with the dead. A clairaudient medium at a séance would typically report an inner voice dictating messages, sometimes transcribed on the spot, distinguishing the claim from direct voice mediumship, where the sitters themselves were meant to hear a voice in the room.

Spiritualist churches and camp meetings in Britain and America institutionalised clairaudience as a recognised platform gift alongside clairvoyance, and it remains part of the working vocabulary of contemporary mediumship and of some New Age channelling practice, where a practitioner may describe "hearing" guidance from a spirit guide or higher self rather than seeing or simply knowing it. The claim has always been treated as a variant of the broader extrasensory perception idea rather than a separate faculty requiring its own theory, which is part of why it was never singled out for dedicated experimental attention the way telepathy and clairvoyance were.

No research programme has isolated clairaudience as a distinct experimental target the way Rhine's laboratory isolated telepathy and clairvoyance with separate card-guessing conditions. Where it appears in the psychical research literature, it is almost always folded into the general study of mediumship and trance communication, tested, when tested at all, using the same techniques used to evaluate a medium's claimed information overall: cold-reading analysis, comparison against what the medium could plausibly have known beforehand, and blind judging of transcripts.

Ganzfeld researchers have noted that some "receivers" report their impressions as words or an inner voice rather than images, but this is treated as a variation in reporting style within the ganzfeld protocol rather than evidence for a separate clairaudient channel. Because no controlled study has ever set out specifically to test whether people can hear real information from a source inaudible to everyone else, clairaudience carries no dedicated evidentiary record of its own, positive or negative; its status is inherited entirely from the wider and already unreplicated record on mediumship and general extrasensory perception research more broadly.
