Joanne Milne suffers from Usher syndrome and was deaf from birth. Jo underwent a life-changing operation to have cochlear implants fitted.
On March 24, Jo's bilateral implants were switched on, allowing the 41-year-old to hear for the first time ever. Jo's mother recorded the video that shows her daughter overcome with emotion as she listens to her doctor as he recites the days of the week.
Milne, who's from Gateshead, England, also started losing her eyesight in her 20s due to the rare genetic disease.
She told BBC, 'I can already foresee how it's going to be life-changing and the implants will get better and better over time. I'm so so happy.'
The Journal says a friend of Milne's, Treymane Crossley, created a music soundtrack for Milne. It included a song from every year of her life.
The playlist was then shared on the radio, and the DJ tweeted that everyone in the studio had burst into tears.
