Wind Noise on Sportwagon (long)

Has anyone else experienced a strange noise on their Sportwagons when they drive with ONLY the back windows down? Either side, or both, doesn't matter...
Noticed it tonight on my '03 Linear SW. Had our two Bulldogges in the back and wanted to give them a little extra air. Started down the road when I heard it. I don't notice it with the front windows down (by themselves or in conjunction with the rears--same with sunroof). It sounds like some strange, low-pitched, pressure thumping sound--whumpppf,whumppppf,whumpppf (almost like what you would expect if the tires were going bad (not the case--only 10k on the car). It almost hurts the ears. It is close to the same noise we used to hear on my wife's early 80's MB 300D--same deal, only with the back windows down...
My guess is some type of pressure transient (venturi effect?) caused by wind going by the window?!?!?!
Any ideas?
