Sound can be used in several ways in films. Ambient sound creates the atmosphere of a place, while synchronous sound emphasizes key audio elements. Sound bridges help transition smoothly between scenes. Sound effects add realism or psychological impact, while diegetic sounds come from visible or implied sources in the story. Non-diegetic sounds do not have a visible source. Contrapuntal sound contrasts with visuals to create new meaning. Voice overs and theme music are also used to convey meaning and set the tone.
