The world around you is full of sounds. This makes up the aural field that you are in. Without this feedback, your brain would have a hard time adjusting. The sounds that surround you create a sense of awareness. Pick an area: your home, outside at the park, at school. Now in this area, close your eyes. What do you hear? How many sounds can you pick out? Also, how do you feel? Sound can also convey emotion.
