Sound

Diegetic Sound

Sound that comes from the world of text (real sound, e.g. doors opening),

                                            

Sound Effects

Sounds of objects added to the ambient sound.

Non-diegetic Sound

This is sound outside the world of text (e.g.theme tunes, soundtrack).

                                             

Voice-over

The thoughts and dialogue of a character, but it is not diegetic as it is not part of the real world of the text. This can be classed under asynchronous sound, as we do not see its production.

Sound Bridge

Sound effects that we hear in one scene and carry over to the next. Alternatively, it can be a sound from the location that is being cut to, but we hear it first before the cut.

Synchronous Sound

Sound which is produced in the world of the text and can be viewed being created and produced (e.g. dialogue of someone speaking).

Asynchronous Sound

This is sound which is in the world of the text but the audience cannot see it being produced and therefore it has more significance (e.g. the sound of footsteps, but we are not shown the feet walking, we only hear it).

                                            

Contrapuntal Sound

This is non-diegetic sound which can clash with the diegetic sound we hear. The music soundtrack clashes with the tone and mood of the scene (e.g. a happy jolly pop song during a scene of violence).
