I just want to share this experience I had yesterday and hear others' stories.
I got asked to do a short film yesterday. It was shot on DSLR and looks lovely. There's no dialogue and concerns a recently bereaved mother. I used two sounds to have a particular effect.
I added in the sound of thunder for no other reason than to highlight an internal emotion from the central character. It signified the beginning of her grief and it's outpouring in the last scene. It also fitted into the dull grey colour of the outdoor scenes (rural mountainous Ireland). I'm not talking huge claps but that gentle rumble of an impending storm.
The other sound was that of of air conditioning in a huge echoey bunker throughout the scenes that take place within the small cottage. It's mixed very low but is intended on making the audience feel uncomfortable. I think it creates the sense of a large empty space, the obvious link being the mother's son who is now not in her life.
I've used sounds for their dual meaning before but never so consciously. How has anyone else used a sound for a dual meaning in their films?
