What caused Beethoven's deafness?

Beethoven began to lose his hearing at age 28. By age 44, his hearing loss was complete, most likely caused by compression of the eighth cranial nerve associated with Paget’s disease of bone.
He could apparently still hear some speech and music until 1812. But by the age of 44 (four years after he composed ‘Für Elise’), he was almost totally deaf and unable to hear voices.

No humor from me on a great composer who became deaf.

Beethoven was one of the greatest composers in history. His deafness was nothing to laugh about. But it is possible he wasn’t completely deaf.

I absolutely LOVE “Moonlight Sonata.”
Too bad Beethoven lost his hearing listening to 90’s Hip Hop. I get it though. That music is FIRE…

WHAT????
