Sound of a Letterbox Closing

As the audio begins, the listener is introduced to the distinct, metallic sound of a letterbox. A creaking noise is evident, showcasing the function of the letterbox as it opens to receive mail. The sound of the metal hinges and the light scrape of metal against metal adds authenticity to the piece. A moment of silence follows, perhaps indicating the brief pause as letters are dropped in. Eventually, the climax of the audio comes with the resonating slam of the metal letterbox, echoing slightly before it fades away. This slam is a clear, crisp sound, powerful and definitive, symbolizing the end of the transaction and the letterbox returning to its original state.
