Should be the same for '05 and '06. They increased the soundproofing in the '05 to match the QX. The rest is the same. The '04 is louder, but weighs a couple hundred pounds less, much of which is sound proofing, which means its slightly faster. On a side note, my Armada with A/T tires is more quiet than my G35 at highway speeds.emelius said:Does anyone know the average highway noise level in an LE compared to a QX56, or where on the web I might be able to find such details?
I just happen to have the latest issue of C&D on my desk here at work (don't ask why), here is some measured data from their charts.scr38 said:The average noise level at highway speeds is about 80 db in most vehicles. I will measure my Armada as soon as I get the chance.
They don't know what they are missing.......92TripleBlack said:Only rating I could find was 69 DBA at 70 MPH for a 2004 Armada, prior to the soundproofing being added. Seems like the Armada hasn't been reviewed by the big mags since '04.
