Tim Barlow (born 18 January 1936) played Tyssan in the Doctor Who story Destiny of the Daleks. He is deaf, which is the result of an incident with a rifle during his army service. In 2008, after the time of filming, he received a cochlear implant, allowing him to partially 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.
