A lot of people don't know that Beethoven wasn't actually DEAF, he was just incredibly hard of hearing. He had his pianos fitted with metal rods attached to their frames that would poke out so that he could lean his head onto them and listen to his own playing through bone induction. None of his pianos survived over time; but that's the historical fact of it. Myself, I can't even hear myself chewing ICE. I've no auditory ability whatsoever since my little brain started dissolving. It was actually the second symptom of my illness after my childhood epilepsy returned. Then the memory started to go, and I lost my career over it. Just gets worse from there, but I won't bore you. Anyway, yeah. Beethoven could hear. A LOT of people in the "Deaf Community" can actually hear with electronic help; they simply don't wear aids and "choose to identify as Deaf" for some stupid reason. Truth.
I call them "Capital D's" and stay away from them like lepers; they're horrid selfish people who do NOTHING to contribute to Society in general. I am deaf. NOT "Deaf". I even sell a line of clothing online, shirts and things, saying stuff like "DEAF AS A TURNIP" and etc. just to tick them off.
It works. Beautifully.
