Mom hears music during day and night. Says an air conditioner makes loud noises and water rushing at night. This has happened suddenly. Mom is 87 and got a good review from Dr last month. Mom has never worried about things and has not showed depression or anxiety. Does exhibit memory loss.
Tinnitus can cause this as well as some medications. All you can do is (at least for me) is tilt your head, listen for a minute and then say, "Hmmmm. I don't hear what you are hearing, I'll have to check it out."
Sometimes she forgets and sometimes she doesn't. Sometimes she tells me I need to have MY hearing checked! Lol!
