Once it hits the damper(?), then its just sound resonating all the way through to the cabin.
(Pic is from WRX forums, but same parts for most cars. Our Rav4 has it too!)
Found this from Porsche friend over Skype.

I think you are picturing what happens backwards there Pack. The sucking engine is sucking air in the intake is not pushing it. The air rushing past the branch of the sound generator creates the noise. There is no air entering the generator really. Can't find the thread but there were a couple of guys that tried to plug the hole in the side of the intake with smooth walled fittings and they got sucked right in (the plugs not the guys). The sound tube does not give, nor take air in any way shape or form.
