Use of Sound: Research and Incorporation into our Thriller

TYPES OF SOUND

Diegetic Sound: Sound that occurs within the fictional world, in which the film explores.  For example, if someone screams in the film, their scream is diegetic sound, because it is sound in consequence of an action or happening within the story.  This sound does not have to be recorded on set, it can be added in the editing stages.

Non Diegetic Sound: Sound that doesn't happen within the fictional story, often music is used to add feeling or create a certain atmosphere, this is an example of non diegetic sound because the characters are not hearing what we hear and it doesn't affect them, only the audience.

On Screen: Sound that can be traced back to it's source, which is on the screen.  For example if an alarm went off and we could see the alarm in the shot, this is on screen (diegetic) sound.

Off Screen: Sound that is happening outside of the shot.  This sound remains diegetic however, due to it happening inside the fictional story.  For example, if a scene faded to black or switched angle and you hear the gunshot but cannot see the murderer, this is Off Screen (diegetic) sound.

Parallel: Sound that enhances, emphasizes or compliments what is happening on screen.  For example, in 'Jaws' the tense build up music signifies the incoming of danger and heightens tension/suspense, in relation to the image of a shark.
