Non-Diegetic Sound Analysis

Non-Diegetic Sound is sound that is outside of the films narrative and therefore the characters in the film can't hear it, it is done to effect the audience. This could include: a soundtrack that is played over the top of the film but that the characters cannot hear, often these soundtracks are played over montages of stock characters or over an important scene such as a fight scene. Voiceovers are also a form of non-diegetic sound as these are not including as part of the films narrative. Sound effects can be non-diegetic as they are added in after over the top of the film, but aren't ambient sound that the characters can hear.

• The non-diegetic music cuts in at the very start of this scene, there is a clunking beat which sounds like metal being hit on something and each beat happens in time with the footsteps. This immediately grabs the audiences attention as it builds tension because it emphasises the importance of the character walking and that something is about to happen because the sound is very loud and consistent. 
• The metallic beats continue and some other more exciting music cuts in over them, this cuts in when we see the character going to put his bag through security. This shows the audience that something is about to happen and it will have something to do with this character and the security guards. The sound creates excitement as the audience are anticipating what is going to happen next and know that something will happen due to the sound increase and the soundtrack becoming more fast paced.
• The sound continues and other diegetic sounds cut in as well, it is all very loud and tense and then a "swoosh" sound cuts in and there is silence when we see the main character with lots of guns under his coat. This complete cut out of music is significant and sometimes silence can be as effective as loud sound effects. The sound was so loud and there was about 4 different sound types happening, by cutting all of these out at once the audience are focused on just the guns alone which shows this is a significant moment in the scene/narrative, as it is the first time the audience see the character is a potential threat. 
• There is a non-diegetic falling, almost like a wind/air, sound effect when the man is falling down in slow motion after being hit. This emphasises the strength of the character that pushed him to the audience as it shows the man is falling very hard and is helpless. 
• The sound effects cut back in after the first shooting and the sound is tense but exhilarating. The sounds sound slightly like alarms which ties in with the narrative as the characters are breaking into somewhere. 
• There are loud non-diegetic drum beats when the shot of the feet running appears, these continue and we see the security emerging. Drum beats are conventionally used as a way to build tension within an audience. They give connotations of an increasing threat or danger in some form or another as they are loud and can be threatening. 
• The music changes it's tone and becomes slightly quieter but still very exciting as the second round of shooting begins. The music reflects the skill of the two dressed in black with sunglasses and is used to allow the audience to perceive them as cool as they aren't phased by the fact they are outnumbered and they continue to fight without fear. Music similar to this is often used in action films as it builds suspense in fighting or car chase scenes etc. 
• A slow motion "swooshing" sound effect cuts in as the female does a run up/flip against the wall. This is used to draw the audiences attention to her skill and to make her seem athletic and in control. 
• Sound effects are used when the female is fighting and kicking the man holding the gun. These are used again to make the audience aware of the characters skill and to make her appealing to the audience as some of them may want to be like her because she is independent and breaks some of the stereotypes associated with women. 
• The non-diegetic music increases as the other stock character is shown, this emphasises his importance in the narrative and makes him seem appealing due to his skill and fearlessness. 
• The music becomes slightly sci-fi like when the character is walking and the bullets are flying through the air. This links to the genre and emphasises this to the audience. The character does cartwheel and this sound continues indicating that the character could potentially have a sic-fi/supernatural element to him or he could just be extremely skilled at fighting.
• The music cuts out for a moment whilst the character is stood behind the pole and then cuts back in when he re-emerges and starts shooting again. This shows his importance and makes the audience excited as they are hooked on the fight scene and want the protagonist to win. 
• The sound increases as the character is running and then fades out as the last man falls to the floor. This signifies to the audience that the fighting is ended for now and that the man and the woman have been victories. 
• The music gets louder and louder and then changes tone to a different, but still just as dramatic tone when we see the bomb. This hints at the narrative and the combination of the music and the close up shot used shows that it is significant in the plot and the audience are meant to pick up on this. 
• The music gets far quieter in the cut shot to the different characters somewhere else in the building, this indicates that the two characters in the lift are more key in the narrative or at least more important in this scene. The difference in sound shows a contrast between the two environments, one creates a far more dangerous tone whilst the other is tense but less so. 
• The sound effect of the two characters in the lift shaft as they cling on to the rope is very dramatic and is used to increase anticipation in the audience and emphasise how dangerous the situation is. 
• An explosion sound effect is used as the bomb explodes and the floor is blown up. Sound effects like this are often used in action or adventure films to emphasise the danger of something or to create suspense and excitement in the audience. 

Non-diegetic soundtracks can often completely change the tone of a scene or successfully emphasise the importance of something. In action films sound effects and dramatic music involving loud noises e.g. drum beats are often used, especially in scenes of violence or extreme importance. In romance films the non-diegetic music is often used to show a connection or to emphasise romantic feelings, especially in scenes where the protagonists are together.
