I have noticed this since I bought the car but no one at Mitsu could tell me what it was except for a rare wind noise.

but it does sound like it is around 30 hz, to test this the front windows must be up and the rear down. Afterall I know I cant be the only one hearing this sound of "transfer Function"

I've only recently found/FELT that one... didn't notice until just a few weeks ago. Scared the crap out of me. Anyway, I think that has more to do with the aerodynamics of the car, but the acoustics of the interior certainly come into play. I'd say that sound you're hearing is the resonant frequency of some body panelling inside the car, so when the panels' motion is driven by the wind coming into the car, it really starts oscillating like crazy.
