Has anyone else noticed an odd noise when driving with their back windows down? It's so annoying that I feel like my ears are going to pop and I can't hear anything but the weird noise of the air coming in the back windows, it's not so bad when all the windows are down but when the front ones are up and the two back ones are down it's so loud?! I wish I could explain it better, and I wasn't even sure which topic this would even fit under. All I can think of is it must be the aerodynamics of the Vibe...
It's called "chuffing" and it's caused by acoustic waves being formed inside of the cabin... If you do it just right, you can watch the front door panels move about 1/2" lol.. It's the same concept as a bandpass subwoofer enclosure.. cept you are inside of it.. lol.
I had not run this way yet with my Vibe, but had the same thing on a '93 Ford Escort wagon and a 2001 Accord. Oddly enough, my '97 Civic doesn't do it.

OH thank goodness, I'm not going crazy then.... YES, it does sound like a helicopter, can't wait to scare the crap out of hubby the next time I have him in the car I'm going to put down the back windows and pretend I don't hear it?!!! Gotta have a lil fun where I can!

You can also make it happen with all the windows up but the moonroof completely open. Put the car around 25-35 then reach up and pull that plastic spring loaded bar down that pops up when the glass slides back. As far as I can tell the only purpose of that piece of plastic is to stop the chuffing phenomena.
yeah we actually called the dealer and they said its a aerodynamic design flaw but i heard it happens with many cars. some people cant hear it which sounds crazy cause it feels like your ears are going to blow out.
