Sitting in the Mac room

I am sitting in the Mac room waiting for people to come by if they need help with Digital Media. There is only me and one other girl sitting here doing work. The only sound could I hear constantly is the old air conditioner. The sound of the air conditioner is low and has not stop yet. The mechanical noise slightly changes from slightly loud to slightly quiet. It then repeats these changes in volume again in a consistent fast pace. As time goes by, the other girl would make some sounds that is typical for a college student to make. I can hear her rustling paper, fidgeting in her chair, sighing or yawning, and typing on her iPhone. These sounds are very light and almost unnoticeable. They also do not last longer than a second. If I had to give this whole soundscape a representational image I would chose a spinning wheel of a bike. The appearance of a spinning wheel does not change that much. Sometimes it would jiggle or wiggle a bit because of the uneven path or debris. However, the wheel does not stop spinning until someone stops it. This soundscape has a few random sounds made by the girl in the room but the air condition is always consistently playing in the background of the inactive Mac Room.
