As the audio begins, the subtle, low hum of machinery in operation fills the air. It's a steady, rhythmic sound, consistent and unchanging, suggestive of a machine running in a continuous cycle. This is not the deafening roar of heavy machinery, but the more muted drone of a smaller, lower-level piece of equipment. It's a constant background noise, like the soundtrack to a scene in a factory or workshop. The sound is steady, like the heartbeat of the machine, providing a sense of motion and activity. As the sound continues, it creates a soothing, almost hypnotic rhythm, a testament to the tireless, ceaseless work of machinery.
