The audio titled "Door Knocking" unfolds with the distinct sound of a hand rapping against a wooden surface. The knocking is crisp, resonating with the unique timbre of wood being struck, suggesting the door is made of this material. The sound effect repeats, creating a rhythm of knocks that replicates someone persistently seeking to gain attention or entrance. The echo of each knock dissipates slowly, subtly filling the silent gaps between each knock and painting an auditory picture of a quiet, possibly empty, space beyond the door.
