Auditory hallucination

Revision as of 23:46, 8 March 2018 by >Josikins (Grammatics)

Auditory hallucinations can be described as the experience of hearing spontaneous imaginary noises.[1][2] These hallucinated noises either occur randomly or manifest in the place of noises that are subconsciously, or consciously, expected to happen. The most common examples of these include hearing clips of sound such as imagined music,[1][2] voices,[1][2][3][4][5][6] tones,[1][2] popping,[1][7] and scraping,[7] but can also be an infinite variety of other potential noises that are stored within one's memory.

The experience of this effect can be broken down into three distinct levels of intensity. These are described and documented below:

  1. Partially defined embedded hallucinations - At the lowest level, the hallucinated sounds lack clarity and may be indistinct, muffled, and difficult to make out.[3] They are also only heard embedded within real sounds occurring within the external environment. For example, one may hear subtle music or voices embedded within the sounds of the wind, cars, and rain.
  2. Partially defined separate hallucinations - At this level, the sounds remain only partially defined, but are heard on a separate layer of their own instead of only manifesting themselves as embedded within other noises.
  3. Fully defined separate hallucinations - At this level, the sounds become fully defined in their clarity, meaning that the content of the hallucinations can be recognized and heard perfectly as if they were actually occurring externally.[3][8]

Auditory hallucinations are often accompanied by other coinciding effects such as auditory distortion[4][5][6][8] and auditory enhancement.[1][3] They are most commonly induced under the influence of moderate dosages of hallucinogenic compounds,[9] such as psychedelics, deliriants, and dissociatives. However, they can also occur less commonly under the influence of stimulant psychosis, cannabinoids, and during sleep deprivation.[10][11]
