William Roache, who plays Coronation Street's Ken Barlow, has revealed that he's 50 per cent deaf in both ears and needs visual cues when filming his scenes.He said: "People don't know I have got a hearing problem. Deafness is extremely isolating. I live in a cocooned world. I could be having a normal conversation and certain things I just won't hear. I can't hear watches or alarms, footsteps or the rustling of paper. The floor manager has to give me a visual cue, a hand signal, and it is just something that I have learned to live with. I have put up with it all these years."
