Sound of wind doesn't change when player turns around.
You should hear a loud noise when you look straight a wind, less, when behind and almost nothing with your "front" ear, when you turned one side.
It should give a good feeling of wind, but at this moment sound just confuses me when I'm turning around. It always blows from my left, doesn't matter which direction I'm looking.
Just play same samples in both ears separately, depending on direction of wind, head and player's movement (when you are using transport).
