The audio starts with the low hum of machinery, hinting at the mechanical process about to unfold. The listener can almost visualize the massive boarding-ramp, also known as a gangplank, used in various transportation modes such as ships or airplanes. Gradually, the hum intensifies, indicating the activation of the hydraulic system that controls the ramp. There is a sudden, echoing thud, followed by a metallic grinding sound. This can be identified as the ramp beginning its descent. The pace is slow and measured, the sound echoing the weight and size of the ramp.

The grinding sound subsides slowly, replaced by a steady mechanical whirring. The listener can almost feel the ramp gradually level out, the incline decreasing until it finally meets the ground with a low, resonant thud. The hydraulic system sighs in relief as the process concludes, the machinery hum
