Complete loss of hearing; total deafness or the total inability to perceive sound sensations.
From Greek ana- (not, without) + akousis (hearing). This variant form of anacusia appears in medical literature as an alternate term for profound hearing loss.
Anacusis and anacusia are basically the same thing—showing how medical terminology often has multiple names depending on which doctor or textbook you're reading, like having synonyms in the language of medicine.
