Joanne Milne, a 40-year-old woman from England, suffers from the rare condition known as Ushers Syndrome.
Joanne was born deaf and registered blind. She was recently fitted with bilateral cochlear implants as seen in the above video, which allow her to hear.
Once the implants were turned on, the doctor begins to recite the days and months of the year. Joanne starts to sob when 40 years of silence is broken.
Watch the amazing moment when she hears for the very first time.
