摘要

Ludwig van Beethoven was 28 years old when he first noticed a ringing and buzzing in his ears. Soon he was unable to hear high notes from the orchestra; speech became indistinct. By 1802, four years after the first symptoms, he was profoundly deaf. Beethoven fell into a deep depression. He describes this period in his Heiligenstadt Testament, meant to be read after his death: For me there can be no relaxation in human society; no refined conversations, no mutual confidences. I must live quite alone and may creep into society only as often as sheer necessity demands.... Such experiences almost made me despair, and I was on the point of putting an end to my life—the only thing that held me back was my art... thus I have dragged on this miserable existence. In 2001, Scott N. was 34 and had lost all of his hearing. A surgeon inserted 16 tiny electrodes into his inner ear, or cochlea, and connected them to a small package of electronics implanted under the skin. A year later, Scott came to author Dorman's laboratory at Arizona State University to test his understanding of speech. The results were extraordinary: Scott recognized 100 percent of more than 1,400 words, either in sentences or alone, without any prior knowledge of the test items.
