We asked Paul Farrell of the American Speech-Language Hearing Association (ASHA) for an answer to this one:
“Musical Ear Syndrome (MES) is a rare condition that causes patients with hearing loss to have non-psychiatric auditory hallucinations. The hallucinations are usually musical in nature and can range from popular music, orchestral symphonies, or radio tunes.
Musical hallucinations can disappear without intervention. When hallucinations are bearable, some patients can be reassured without any other treatment. However, in other cases patients musical hallucinations are so disturbing that treatment is indicated. I would recommend that you seek consultation with a physician, preferably a neurologist or otologist to discuss your case and if any treatment options available.”
Maybe not the answer you wanted to hear, but we agree with his assessment — try to find a specialist. I’m sorry that you’re suffering from this, it doesn’t sound fun. Best wishes.
