The audio begins with the distinctive sound of a metal handle being turned with a strong clank. The sound is followed by the distinct groan of a heavy metal door, resonating with a squeaky, creaky noise as it's being opened. The door's hinge, burdened by the door's weight and age, lets out a screechy protest. You can almost visualize the rusty, metal hinge struggling to keep the door's weight in check. Suddenly, the spring-loaded mechanism comes into action, producing a resonating, metallic echo that fills the space. It's a distinct sound that hints at the door's automatic function. The door then creaks shut, the spring contracting with a groan, the hinge letting out one last screech as the door returns to its closed state. The handle clanks once more, signifying the end of the sequence. The entire experience draws a vivid picture of an old, heavy, spring-loaded metal door being opened and shut.
