Musical ear syndrome (MES) describes a condition seen in people who have hearing loss and subsequently develop auditory hallucinations. "MES" has also been associated with musical hallucinations, which is a complex form of auditory hallucinations where an individual may experience music or sounds that are heard without an external source.[1] It is comparable to Charles Bonnet syndrome (visual hallucinations in visually impaired people)[2] and some have suggested this phenomenon could be included under this diagnosis.[3]
