Audible Voice Phenomena (A.V.P. or AVP) refers to the subjective experience of hearing voices that are not generated by external sources and are often characterized by a sense of presence or agency. In contrast to Auditory Verbal Hallucinations (A.V.H. or AVH), which typically involve disembodied voices speaking, A.V.P. encompasses a more diverse range of experiences, including voices, sounds, and even sensations. A.V.P. may or may not be recorded on electronic devices, such as audio recorders or video cameras during a Paranormal Investigation or Ghost Hunt.
Historical Background
A.V.P. has been documented throughout history in various cultures and societies. The concept of “auditory hallucinations” was first described by the ancient Greeks, with the philosopher Plato (428-348 BCE) mentioning a patient who heard a voice warning him of impending doom.
In the 19th century, the French psychiatrist Jean-Martin Charcot (1825-1893) described cases of patients who heard voices during states of hypnosis. However, it wasn’t until the 20th century that A.V.P. began to receive more systematic study, particularly in the fields of psychology and psychiatry.
A.V.P. can manifest in various ways, including:
1. Voices: Disembodied voices that speak, whisper, shout, or sing. These voices may be perceived as belonging to internal or external sources.
2. Sounds: Various noises, such as whispers, hums, hisses, or tapping sounds, that are not necessarily vocal in nature.
3. Sensations: Feelings or sensations that are perceived as auditory, such as the sound of footsteps, rustling leaves, or even a sense of presence (Sensory Deprivation and the Sense of Presence).
4. Auditory illusions: Misinterpretations of internal physiological or sensory events, such as the sound of one’s own heartbeat or the rustling of clothing.
Example: Hearing a voice or sound, or other noise not heard by ear on an audio recording, seemingly appearing by an outside force or entity or an E.V.P.
Causes and Risk Factors
A.V.P. can be associated with various neurological, psychological, and psychiatric conditions, including:
1. Schizophrenia: A.V.H. is a common symptom of schizophrenia, although the presence and nature of A.V.P. can vary widely between individuals.
2. Bipolar disorder: Some patients with bipolar disorder may experience A.V.P. during manic or depressive episodes.
3. Traumatic brain injury: Head trauma can lead to the development of A.V.P.
4. Neurological disorders: Conditions like epilepsy and multiple sclerosis may be associated with A.V.P.
5. Substance use: Certain substances, such as psychedelics and hallucinogens, can induce A.V.P.
