A Weirding Module is a sonic weapon introduced in and specific to Dune, the 1984 David Lynch film adaptation of Frank Herbert's 1965 novel of the same name. In the film, the device is a sonic beam weapon that translates specific sounds into attacks of varying potency, used by House Atreides and later by the Fremen armies. In the novel, Paul Atreides and his mother Lady Jessica teach the Fremen the Bene Gesserit martial art referred to by the Fremen as the weirding way.
Director David Lynch is said to have adapted the weirding way into the Weirding Module because he did not like the idea of "Kung-fu on sand dunes". The change literalizes Paul's line "My own name is a killing word." In the novel, the Fremen shout his Fremen name, "Muad'Dib," as a battle cry; in the film, the Fremen are surprised to find that saying "Muad'Dib" is a powerful trigger for the Weirding Module.
The Weirding Module appears in the computer games Dune (1992) and Emperor: Battle for Dune (2001), and the concept is adapted into "sonic tanks" for the games Dune II (1992) and Dune 2000 (1998). There is no reference to this technology in the original novels.
