Automatic Door 2

As the audio begins, the unmistakable sound of a car engine humming softly in the background is heard. Suddenly, a mechanical whirring sound fills the air, indicating the automatic operation of a car door. The door smoothly glides open, the sound of well-oiled machinery clearly audible. After a brief pause, there's a sudden, forceful noise as the automatic car door shuts with a resounding slam, echoing the finality of a sealed vault. The engine's hum gradually fades, leaving behind the striking silence in the wake of the door's powerful slam. The audio paints a vivid picture of an automatic car door's operation, from its seamless opening to its emphatic slam shut.
