Question

which of the following is an example of non - diegtic sound?
○ a ringing telephone that a character answers
○ footsteps in a scene
○ a characters dialogue
○ background music in a films score

Explanation:

Non-diegetic sound is audio that exists outside the fictional world of a media work; the characters within the story cannot perceive it. Diegetic sound originates from within the story's world and is detectable by the characters. A ringing phone, footsteps, and character dialogue are all sounds that occur within the story's setting and can be interacted with or heard by the characters, making them diegetic. Background film score music is added for the audience's benefit and is not part of the story's internal environment, so it is non-diegetic.

Answer:

Background music in a film's score
