This is a Reflection on Theory of the Film: Sound by Bela Balazs

It seems to me like the writer is attempting to convey the idea that silence is not simply a lack of sound, but an abundance of sound where there once was none. I can see their point, and I am especially fond of their description of silence and space where they speak of being able to hear things you wouldn't normally is what silence is. Being able to hear the faintest of sounds brings a good feeling of silence rather than a bad feeling that I get in an environment with a complete lack of sound. Silence is therefore a lack of sound in your immediate vicinity. The sound silence of film should be enhanced with picture and vice versa with the silence of a picture being enhanced by sound. The two go so well together in film, so not having a good quality of one or the other is detrimental.
