Beethoven could still hear after going deaf:

Upon going deaf, Beethoven discovered that if he bit onto a metal pole that connected to the piano he was playing, he could hear almost perfectly well. This process is called bone conduction, and while technology has evolved, the science is the same: Vibrations are transferred from the conductive metal into our bones. When this happens, our ears pick up the signal with no sound distortion.
