I thought you were in Texas this week.
Yep. Just outside of Dallas. Trying to see if I can borrow a rifle and get directions to the school book repository, then go out for a picnic on a nice grassy knoll...
Microphone outside the car, eh? I wonder if there will be a linear relationship between noise outside the car and noise inside the car? Is it possible that a significant part of the sound you perceive as "road noise" is really noise generated harmonically within the interior of the car by vibrations from the wheels and suspension?
I will be very interested to see how this comes out.
