Inspired by his father, who was becoming deaf, he worked to invent a device that could make a person hear. Even as a child he wanted to help. In his own words, he said he wanted to “fix ears”.

8. The Bionic Ear The Bionic Ear has helped lots of people over the past 25 years. In fact, my step sister has a Bionic Ear. It has a very special case that protects it from water. She has just celebrated her 10 th year of having the Bionic Ear. She is 11 years old. There are two parts to the bionic ear. One part is placed under the skin behind a person's ear and the other part is the electronic part. The second part is worn on the outside of the head.

9. How it works A bionic ear these days are now known as a cochlear. It is an hearing tool which stimulates nerves, using electricity, in the inner ear. The bionic ear helps a deaf person hear another person speak. A speech processor which turns the voice sounds into electrical signals, a transmitting coil which sends the signals to the equipment inside the deaf person's ear.
