The audio piece titled "Door Knob 1" starts with the distinctive sound of a door knob being gripped, the metallic clink echoing slightly. The handle turning mechanism can be heard, a soft grinding of metal against metal, intricately designed to allow access. This is followed by the heavy yet smooth motion of the door being pushed open, the hinges letting out a subdued creak. There's a pause, perhaps a moment of hesitation, before the door is then forcefully shut. The audio concludes with the resonating slam of the door, a sound that reverberates, leaving an impression of finality. The sequence of these sounds paints a vivid picture of interaction with a door, from the initial turning of the door-knob, to the eventual slamming of the door.
