As the audio titled "Item Tumbling Down the Stairs_1-2" begins, the initial sound that hits the ears is a light tap, akin to the kicking of a soccer ball. It's followed almost immediately by a series of echoing thumps, each one growing louder and more intense, as if the ball is bouncing haphazardly down a staircase. The rhythm of the sounds reveals an object in constant motion, falling, tumbling, and hitting each stair with a distinct, resonating sound. The noise fills the space, reverberating around, evoking a sense of a large, empty staircase, and an object's relentless journey downwards. This series of sounds ends abruptly, as if the object has finally reached the bottom, leaving behind a silence that starkly contrasts with the preceding cacophony.
