As the audio begins, the distinct sound of a school door, made of sturdy metal, can be heard. It's the familiar, sharp clank of a door latch being engaged as someone prepares to shut it. The echo in the surroundings subtly indicates the typical spacious hallways of a school. There's a palpable sense of urgency, as if the door is being shut hastily, but with a firm hand. The door swings on its hinges, creating a slight metallic creaking noise that's almost drowned by the subsequent slam. The finality of the sound - a combination of the metal latch falling into place and the door colliding with the frame - resonates, signifying a door closing, perhaps signaling the end of a school day or the beginning of a class. The last echoes of the door slam fade away, leaving behind a brief silence.
