The incredible moment was filmed by Joanne Milne's mother and shows her bursting into tears in shock and delight.
Joanne, from Gateshead in England, was born deaf and has spent 40 years in silence.
But in her 20s, she also started to lose her vision due to a rare medical condition called Usher Syndrome and is now blind.
Having new cochlear implants switched-on has opened up a new world to Joanne though, in what she branded "the most emotional and overwhelming experience" of her life.
Hearing things for the first time is so, so emotional, from the ping of a light switch to running water. I can't stop crying.
"I'm still in shock now. The first day everybody sounded robotic and I have to learn to recognise what these sounds are as I build a sound library in my brain," Joanne, who works for the charity Sense said.
"It's one step at a time as it's all so daunting. It's the small things that are huge life changing experiences to me right now."
One of Joanne's friends, Tremayne Crossley, made a music compilation featuring one song from each year of her life to mark the occasion.
He sent it to BBC Radio 6 Music presenter Lauren Laverne, who featured the playlist on her show.
"Just watched a video of today's #Memory Tape recipient having her cochlear implant turned on and hearing for the first time. Studio in floods," she tweeted.
Some of the tracks chosen included Sweet Dreams (Are Made Of This) by Eurythmics, Prince's When Doves Cry, Everlong by the Foo Fighters, Daft Punk's Digital Love and One Day Like This by Elbow.
