"Elevator Ascending with Open and Closed Door on October 25, 2016"

The audio begins with the mechanical hum of an elevator being activated. This is followed by the sound of the elevator doors sliding open, giving an impression of entering into an enclosed space. After a brief pause, there's a clear, distinct noise of the doors sliding shut, followed by a low, steady whirring sound. This sound suggests that the elevator is ascending, moving up through the levels of a building. The whirring sound gradually decreases as the elevator reaches its destination. The audio concludes with the repetitive mechanical sound of the elevator doors sliding open and then closed once again, signalling the end of the journey on October 25, 2016.
