Sound - Secret Diary Of A Call Girl

A non diegeitc sound is used at the start of the scene, it is a quick and sudden sound of brass. This creates a bit of a bang that grabs attention.
From then on there is no added sound used for a few minuites. There are many unfinished sentences and the fact there is no soundtrack helps emphasize the akward atmosphere and showing theres no flow of convosation.
When the woman locks the door the sound is emphasized, this is to make us aware of the sound because it's relevant to the next convosation.
In  the next scene when the man puts on the radio, he turns it off because it does not reflect his anxious mood, this is an example of asynchrony.
A slow soundtrack starts that matches his emotions, and a sound bridge occurs continuing the music to the next scene in the bedroom which also matches the sexual mood that is taking place. However, the slow sentimental music also follows the sad emotions the boy is showing. The music helps the audience feel the sympathy for him.
