Just did an informal test on mine on the way to the office... it was raining, but with limited traffic (I work nights) and DBMeter Pro on my iPhone showed:
MIN: 63dBA MAX: 74dBA AVG: 66dBA
That was at 80 MPH (cruise set @ 82), on 38PSI tires, stock interior over 5 minutes. It included a lane change, which was where the 74dB peak occurred. I know it's quieter than my RC-F was by a fairly decent margin as well... because when I'm on the phone, no one can tell that I'm driving normally. In the RC-F (and my G37S prior to that) - road noise was the first thing anyone commented on.
I plan on going "full @tadda" re: interior treatment soon... but that's more for squeaks and rattles and to increase clarity of the audio system. If it were just road noise, then I'd never bother with it at all. I doubt it will make more than a very slight difference anyway since most of the road noise seems to be transmitted through the glass - not the chassis itself.
