Tapping on a Metal Door

The audio commences with the distinct, resonant sound of a hand making contact with a solid, metallic surface. The rhythmic tapping reverberates, creating a series of echoes that linger in the air. The metallic door seems to be hollow, as the sounds produced are low-pitched and ring out with a unique timbre, distinct from that of traditionally wooden doors. The knocking sequence varies, sometimes soft and tentative, other times more assertive, akin to someone trying to gain attention from the other side of the door. The hollow metal door rings out with each series of knocks, the sounds bouncing off the metal surface and creating a chorus of metallic vibrations. The audio evokes a sense of anticipation, as if waiting for the door to be opened.
