Art of Cinema
The three-dimensional sound design in Gravity adds depth, reality, and intensity to its two-dimensional image.
Another example is in the introductory scene: where to astronauts are talking to each other. To the audience, the sound seems very quiet and distant, yet was very easy to tell which direction the sound was coming from. Without even seeing the characters, the audience is able to determine that a female astronaut is speaking to a male astronaut and which side of the frame each of them is on. The silent, distant sounding voices adds to the feeling of distance as we are shown a picture of the Earth from space.
