29 year-old Sarah Churman describes herself as born deaf.
8 weeks ago she received the Envoy Esteem Implant, a device that uses the natural ear to pick up vibrations and turn them into sound.
Sarah posted a video on YouTube showing the moment it was turned on, and she heard her voice and laughter naturally for the first time.
The hidden device gives patients more natural hearing than any hearing aids, which use microphones and speakers.
6 million people have enjoyed her video since it was posted on September 26. Watch below…
How did she learn to talk so well if she was born deaf? It’s a very touching video, although I find it odd that she can talk so well if she has never heard words spoken.
