Wow that V6 is used in Camry is noticeably smooth.

Certaintly is. Amazingly at 80 km/h the Camry SE V6 is just 2 dB's louder than a Mercedes-Benz S550 and Lexus LS460

I added the S550 from the first page:

i drive a 1995 mazda 323, and i can tell you one thing, at any gear, or speed, you can hear the road, the engine, the gear change, the fuel going through the tubes, and the oil passing through the cylinders, heck you can eevn hear individual molecules of gasoline burning, but i wouldn't trade it for anything i can go to college 3-4 times per week (it's a 25mile journey in traffic) go up and down, and do as much cruising i want on one tankful, and that tankful is for about $30
SWEET!

Guys something to notice here, each 3 dB increment is eventually doubling the noise power.

Just to drag your attention to this guys.
