In the box-opening scene of the thriller film Se7en there is the diegetic sound of the low rumble of the helicopter propellers and the sound of the flick knife blade, and then the cutting of the box. There’s also the use of ambient sound, such as birds tweeting in the background, which juxtaposes the dark story of the film. Then there’s also the diegetic dialogue of the characters. When the opening of the box happens, there’s a dramatic change of pitch and rhythm when the character played by Morgan Freeman realises the box contains something horrifically unexpected, the head of his accomplice’s pregnant wife. The background noise is non-diegetic, consisting of a single underlying high-pitched, eerie note. The foreground noise is a repetitive thudding chord, with an increasing tempo and volume.
The use of this uncomfortable sound increases the suspense and tension for the audience, keeping them hooked on the events unfolding, and causes them to feel anxious. This foreshadows the climax, and is used to tell the audience how to feel, by building up to the overwhelming end of the film.
The audience may respond to the soundscape with uncertainty, not knowing what is going to happen next due to the unpredictable sounds and cross cutting– i.e. cutting to the loud sound of the helicopter propellers, back to the dialogue, as well as the use of the low yet prominent thudding contrasting with the high pitched note in the background. The use of the sound conforms to the conventions of a thriller film, because it successfully builds up dramatic tension and uncertainty. The sinister sounds reflect the menacing serial killer and the dark events, which unfold.
Throughout the scene, they’ve used some editing techniques, which are most prominently noticed with the use of cross cutting. There is a clear use of overlaying of sound with the contrasting deep thudding and high-pitched tone. However, it does not include sound bridging because of the jumping of sounds between each scene. Synchronous sounds are used, for example when the character played by Morgan Freeman is showed using the flick knife, there is the clear sound of this as well as when he opens the box. This is used to exaggerate this dramatic climax, and to have the audiences’’ full attention on what is happening in the scene.

In the opening scene of The Dark Knight Rises, there’s the use of a subtle underscore to slowly build tension as the scene progresses and the diegetic sounds of dialogue between characters and the prominent sounds of weapons and equipment that are being used by the villains. The use of diegetic sound is to inform the audience of what is happening in the scene and to grab the audience’ attention from the start.
The underscore jumps between a harsh prominent, foreboding note to a quick continuous thudding note and then to an occasional singe low note. This underscore becomes more and more erratic and the pace quickens along with the action that is happening in the scene. In certain parts of the scene where the dialogue is important, the underscore is decreasing in tempo and sound so the audience can clearly hear what is happening in the scene.
The use of sound is synchronous, it mimics what is happening in the scene and there are specific moments when the tension is high, so the underscore has replicated the sound of an increasing heartbeat to create tension for the audience. It also prepares the audience for what is about to happen, when the underscore’s tone and pitch is noticeably increasing and then is quickly decreased, it tells the audience that something dramatic and unexpected is about to happen.

The use of sound in a particular scene in Reservoir Dogs is very effectively used to create a reaction out of the audience. The scene starts off with a guy strapped to a chair and another guy who is about to proceed to torture him. The sound of the scene begins as synchronous with only diegetic sounds, like the use of dialogue, footsteps, heavy breathing from the victim and the sound of the villain playing around with various torturing weapons. This use of sound slowly starts to build up suspense and clearly shows to the audience what is about to happen.
The scene then proceeds to take an unexpected turn in the use of sound; the torturer of the scene begins tuning the radio to a specific song known as ‘Stuck in the middle with you’ by Stealers Wheel. As the radio slowly begins to introduce the next track, it is used to build up the wait of the torturer, (this is known as synchronous sound), whilst the villain proceeds to joke around and intimidate the character with the use of his confident attitude. This use of sound is breaking conventions in thriller films by having a contrasting score in comparison to what is happening in the scene.
The use of sound lulls the audience into a false sense of security by using an upbeat score whilst a horrific torturing scene is being carried out. This is an effective way to use sound, because it shows the power and control sound can have on an audience and the manipulation that can be used to change perspectives.
The editing techniques of sound that are used are overlaying, such as when the victim is being tortured you can still hear the groaning and struggling of the character whilst the song is still clearly being played over the top.

The first noticeable sound in this particular scene is the intensified sound of the waves, this use of diegetic sound makes the whole scene feel more intense and suspenseful because it makes the waves seem menacing, unpredictable and threatening to the characters in the scene. There’s also a very subtle underscore that is used underneath the dominating wave sounds, which is a very low quiet note, which just adds to the tension and creates the horror aspect of the film. This note is also increase in tempo as the scene progresses. These non-diegetic sounds are also combined with the diegetic sound of the dialogue. Because the main character in this particular scene is in a complete panic, the dialogue is very loud and has been edited in several places to slow down the pace of the speech, to add to the importance of what she is desperately trying to communicate.
When the audience and the character are unsure of what is happening the sounds abruptly change, the sounds of the waves are no longer heard and the dialogue is cut short. Then there is a sharp, eerie note and then the sound cuts back to just the sound of subtle waves, creating a false sense of security for the characters that are in danger. However, a sharp squawk of a seagull is used to signal that danger is approaching. Then when there are only quiet, subtle sounds, the huge crashing of the shark breaking the surface of the water and the grabbing of the character and his screams create sudden, loud sounds in order to frighten the audience.
The sound used conforms to the conventions by having loud, foreboding, erratic sounds when the characters are in panic and by having almost no sound just before a dramatic event is about to happen in order to frighten the audience unexpectedly. The tone created by the sound also coincides with what is being viewed, therefore the use of synchronous sound is evidently used.
