AKOASM

akoasm: translation

Also referred to asacoasm, acousma, andakoasmic noise. All four terms stem from the Greek verbakouein, which means to hear. The term akoasm was introduced in or shortly before 1900 by the German neurologist Carl Wernicke (18481904) to denote relatively simple, *nonverbal (or *nonvocal) auditory hallucinations such as buzzing sounds, rappings, and rustling noises. Wernicke used the term akoasm in opposition to the term * phoneme (which is used as a synonym for * verbal auditory hallucination).
