The animation source sounds (such as the ones played when the doors open) are not positional over the duration of their playback.

They will remain playing in the same position relative to the players, from the moment they started to the moment they end.

While this might not be noticeable at first, it prevents the use of door sounds for doors that open slowly, such as big hangar doors or roll-up doors with slow mechanisms or sounds for other types of longer animations where this may become very obvious to the player.
