As Akoasma (plural: Akoasmen; of Greek . Ἀκοή "ear") refers to non-verbal, audible hallucinations in mental disorders . Amorphous (unformed), elementary noises (hissing, humming, whistling, knocking, whizzing, hissing, neighing, whispering, but not as an inputting voice) or noise (popping, clinking, shooting, drumming, barking, howling) are perceived. More specific auditory illusions such as the rush of water, bells or organ tones are rarer.
Occurrence
Akoasms can be experienced in the context of mental illness ( e.g. schizophrenia ), but also occur during the epileptic aura . According to Kurt Schneider's classification , acoasms are class 2 symptoms of schizophrenia . In the context of schizophrenia, however, acoasma occurs very rarely compared to hearing voices.
Differential diagnosis
Acoustic hallucinations must be differentiated from noises in the ears, which are based on a disorder of the hearing function ( differential diagnosis : tinnitus ).
