A touching vido has surfaced from Chicago, USA of a little boy hearing properly for the first time after an implant in his ear was switched on.<br /><br />In the clilp, which was filmed at the University of Chicago last month, five-year-old ReShod sits with doctors and his mum waiting for the cochlear implant in his right ear to be activated.<br /><br />When they finally switch the device on, a delighted ReShod keeps saying "I can hear! I can hear!" over and over again.<br /><br />It was also the little boy's birthday so he got to hear a rendition of 'Happy Birthday' properly for the first time. <br /><br />A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear.<br /><br />Unlike hearing aids, which make sounds louder, cochlear implants do the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain.
