A ghost is the most likely cause.
I don’t believe we’ve ever heard it after opening or closing the door. It happens as we approach it. Sounds like it’s coming from the frame on the side with the hinges.
I wish I knew what that means but I appreciate you giving me a starting point. The sound doesn’t happen all the time. Only if we haven’t walked past it in a few hours. So strange.
