Beethoven started going deaf at 25.
For most of his life he was unable to hear the details of most instruments. In his letters he talked about not being able to hear flutes or people singing—sounds that others heard.
For much of his life, he laid his head on the piano while composing, because that was the only way he could hear anything at all. The vibrations from the piano against this side of his head was his auditory experience.
Beethoven wrote his 9th symphony after he went completely deaf—COMPLETELY DEAF.

But what the heck, let’s cancel all he accomplished despite adversity, because he’s a dead white guy.
