The Orphanage - soundtrack and sound effects

In my media lesson I watched a scene of the orphanage, which is a 2007 spanish horror film made by J.A. Bayona, and focused on the soundtrack and the sound effects and looked at what kind of effects it creates and why they use them.

When watching this scene I realised that they edited the main characters voice to mak it deeper, to give him more presence and make him sound more powerful, and the contrast between this man and the woman who's voice is given the effect of talking through a microphone makes the woman seem more distant and vulnerable than the other character, they also give the scene more realism by adding a non-diagetic sound of the woman's microphone clicking on and off. They also record the woman's footsteps and her breathing and emphasise them by making them louder to add tension and draw the audience in. The sound effects of this make the audience tense and begin to imagine sights in which aren't actually there which makes it a lot more dramatic. The soundtrack is also overlapped over sound effects so the outcome is a heavy layer of sound which creates a rich dramatic effect.
