How did Beethoven continue to compose music despite slowly losing his hearing?

Despite gradually losing his hearing, Beethoven adapted his composing techniques by relying on his deep understanding of Music Theory and his ability to visualize sound. He used tools like a special wooden rod that he would place in his piano and bite to feel vibrations, and he also composed music in his mind, often writing down his ideas using meticulous notation. His determination and innovative spirit allowed him to create some of his most profound works during this challenging period.
