As the audio begins, the sharp, piercing sound of a whistle can be heard, implying that something is about to commence. The sound of a pump then takes over, operational and rhythmic, almost like a heartbeat. It's a close-up view and every detail is vividly audible. The pump moves with a creak, an old sound that speaks of many years of use, yet still functioning efficiently. There's a puffing sound accompanying each pump movement, similar to a steam train working tirelessly, puffing out the energy it takes in. The combination of whistle, pump, creaking, and puffing paints an auditory picture of a hardworking machine, echoing with the spirit of industrial age technology.
