YouTube member sloanchurman was born deaf. Now 29 years old, her husband recorded the moment her hearing implant is activated. She explained in the YouTube comments:
"I had an implant put in 8 weeks ago called The Esteem Implant by Envoy Medical. I was born deaf and have worn hearing aids from the age of 2, but hearing aids only help so much. I have gotten by this long in life by reading lips. This was taken as they were activating the implant."
