Sound in media

In media, there are several types of sound used;

The first being Diagetic Sound - these are natural sounds that are all scourced whithin a scene, for example, a conversation between characters, the sound of a door opening, or the sounds of the city(background noise).
For example, in soaps such as 'Hollyoaks', usually only diagetic sound is used to keep social realism.

The second type of sound is Non-diagetic - This is sound that is added after filming to create an atmosphere of tension for example, a theme tune.
A problem with this type of sound is that it may corrupt the scene to be less realistic although an advantage is that it may create more drama.
For example, the iconic theme tune from 'Jaws' automatically creates a tension in a scene.

Other types of sound include;
A sound bridge - this is sound that bridges over two scene and creates a transition from one to the next.
Indicental music - This is a short sequence of music added to emphasise an emotion being portrayed in the scene e.g. a death.
Asychronous sounds - A 'natural' sound that is out of place in the scene, without a scource.
Contrapunctual - This is sound which contrasts an emotion in a scene, this creates an exact binary opposite almost for example, a sad piece of music playing when a charater is portraying happiness.
