A look into the technology which enabled a profoundly deaf woman to hear for the first time after 40 years.
A man whose best friend has recently been fitted with a cochlear implant was given the task of choosing the first music she would ever hear.
Today I met a remarkable young lady who has been given new hope by the breakthrough findings from Sheffield University.
A woman who recently heard sound for the first time has told ITV News she "could not believe" the noise from everyday objects such as her hairspray.
Joanne Milne, who was born deaf, said she was planning to "enjoy every sound" now that she can hear for the first time in almost 40 years.
The mother of a woman who has heard sound for the first time after getting a cochlear implant has told ITV News she was "worried for a month" about her daughter's operation.
Ann Milne, who filmed her daughter hearing for the first time, told ITV News Joanne had taken a "big chance" by going ahead with the procedure.
If the operation had failed, Joanne would not have been able to use her old hearing aids again
A deaf woman, who appeared in an emotional video which showed her hearing for the first time, has thanked ITV News' Facebook followers for their "wonderful comments" on the social networking site.
Commenting on ITV News' Facebook page, Joanne Milne wrote: "Wonderful comments...you're making me cry again! Thanks everyone...I'm still on my emotional rollercoaster!"
Joanne Milne was born profoundly deaf, but she is now able to hear for the first time, thanks to new cochlear implants.
Here she told us she did not mind being deaf until she began to lose her sight too, due to a rare condition called Usher's Syndrome.
After almost four decades of silence, Joanne Milne heard sound for the first time. Here, in her first television interview, she described the emotion to ITV News.
An award-winning celebrity chef who has been going deaf in one ear has urged anyone who suspects they have a hearing problem to "accept that something is wrong" and go for tests.
Multi-Michelin starred chef Jean-Christophe Novelli spoke to Daybreak about how "unbalancing" it is to have a hearing problem.
He said: "It's like your eyes, you've got to have test and the I only regret I have is I think this happened to me four or five years ago and I should have had test. I think people should not be embarrassed and they should have the urgency to find out what is going on."
Dr Marcelo Rivolta, who led the research, said:
Stem cells have been used in animal models of deafness before, mostly the mouse, with different results, but none have shown functional recovery.
What we have shown here is functional recovery using human stem cells, which is unique.
As a proof-of-concept we have shown that human stem cells can be used to repair the ear.
