A discernable thud dominates the audio, signifying the impact of a heavy object, possibly a metal paperweight making contact with a surface. The sound has a distinct resonance, indicative of the material's solidity. It's unmistakably a hard hit, not a gentle placement. Immediately following the impact, a soft but crisp rustling echoes through, the unmistakable sound of a plastic bag being disturbed. The audio suggests the object doesn't just land, but also bounces slightly after the initial contact, creating a secondary, lighter clatter. This series of sounds paints a clear auditory picture of a substantial item falling onto a plastic bag.
