'''Auditory hallucinations''' can be described as the experience of hearing spontaneous imaginary noises. 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, voices,<ref name="Juszczak2013">Juszczak, G. R., & Swiergiel, A. H. (2013). Recreational use of D-lysergamide from the seeds of Argyreia nervosa, Ipomoea tricolor, Ipomoea violacea, and Ipomoea purpurea in Poland. Journal of psychoactive drugs, 45(1), 79-93. https://doi.org/10.1080/02791072.2013.763570</ref> tones and notes, 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:

Auditory hallucinations are often accompanied by other coinciding effects such as [[auditory distortion]] and [[auditory enhancement]].<ref name="Juszczak2013"/> They are most commonly induced under the influence of [[dosage#common|moderate]] [[dosage|dosages]] of [[hallucinogen|hallucinogenic]] compounds,<ref>Al-Assmar, S.
