This audio features the distinct, resonating sound of a door stopper. The audio begins with the metallic zing of a coil spring being released, which produces a sharp, high-pitched echo. This sound is followed by a heavy, dull thud as though a solid metal flange is hitting a sturdy surface, indicating the door has come to a full stop. The interplay between the coil and stopper creates a rhythmic symphony of sounds, emulating the routine yet essential act of a door being halted by its stopper. The audio is marked by a combination of metal-on-metal sounds and the reverberation of the coil, producing a unique sonic experience that accurately represents the functionality and operation of a door stopper.
