In this audio, the prominent sound is that of a metal cover being struck. It starts with a sharp, resonating thump, as if someone hits the lid with a solid object. This produces a loud metallic vibration that echoes in the surrounding. The density of the metal cover is apparent in the sound, rich and full-bodied. The hit is firm and deliberate, causing a ripple of sound that gradually fades into silence. The audio encapsulates the raw, unique noise that only a metal object can produce when struck – a perfect blend of a thump and a resonant ring.
