Sound Research

I have recently started to work on sound in film and I have learned a lot about how sound can make or break potential film pieces. Survey's show that 70% of film viewers watch a film at the cinema because of it's sound. Sound is a key feature to film, as it helps tell the story, makes the shots interesting, and makes it real for the audience. Even when the silent movies came out, there was still Non-Diegetic sound (background music) to make it more interesting. 
The types of sound I have been focusing on are non-Diegetic and Diegetic.  

Diegetic

Diegetic sound is sound that we as audience AND the actors could hear. This includes things such as dialogue, footsteps, music on the radio and background noise on set. Even though these sounds seem real, it is very interesting to know that all of these sound effects are in fact Foyle sounds (Added on after shooting). 

Non-Diegetic

Non-Diegetic sound is the sound we as the audience hear, however the actors on set don't. For example, background music and Voice Over help explain the scene to the audience. However, nobody on set knows anything about it. 

The scene I focused on for my research was taken from James Bond's Casino Royale, Click the video clip to watch the scene.
