Tim Barlow (born Michael John Leigh Barlow) played Tyssan in the Doctor Who story Destiny of the Daleks. He was profoundly deaf at the time of filming, the result of an incident with a rifle during his army service; his deafness was thought to be permanent. However, in 2008, he received a cochlear implant, allowing him to hear again.
He has appeared in films such as The Tall Guy with Jeff Goldblum (playing a blind man) and Hot Fuzz with Simon Pegg. Barlow has written and performed in autobiographical one-man shows such as My Army, about his experience in the military in the 1960s.
His experience with the cochlear implant was the subject of a BBC radio program, Earfull - From Silence into Sound.
