Sound Within Film

There are two types of sound which is used within film, these are, diegetic and non-diegetic sounds.

Diegetic sound is noise which can be recognised within the film world, for example dialogue between characters of the sounds of footsteps when a character is walking.

Diegtic sounds however are split into two types, there is on screen and off screen sound. They are both rather self explanatory. On screen is when it is part of the film world and we can see what is the source of the sound, for example a character which we can see who is talking. Off screen is when we can hear a sound and so can the cahracters in the film, but we cannot see what is making it an example of this could be the noise of traffic when someone is walking down the road, but we cannot see it.

Non-diegetic sound is when a sound is not part of the film world, for example music which has been edited into the scene, or a narration of the film. A good example of this is in 'No country for old men' at the beginnning when the man is talking about his life.
