OK, all this talk got the hamster which lives in my head (usually
dormant) up and running about.  For my trip to Seattle next weekend, I
am borrowing a sound level meter from someone here at work (who is a
noise control engineer) to measure the interior noise level in my van.
Then perhaps two or three years down the road when I get around to
soundproofing my van, I can compare how many dB I've shaved off.

I'll post my uber-scientific results when I get back.
