Default Interior road noise

What could/should designers do to quite the cabin.
It's been said that the hatch area is one of the largest culprits.

There are all sorts of sound reducing materials. Unfortunately all add weight.

True. But what about redesigning the hatch area...maybe even changing it to a trunk.

I hope they'll leave some noise. I don't want to feel like I'm driving a hearse.

I recently took a 3500-mile road trip in my 2005 (with an extra layer of sound mat installed). To me, road noise is a big negative.

I understand that a lightweight hatchback with massive tires is inherently more noisy than a luxury sport sedan. I certainly don't want GM to ruin the car making it vault-quiet. But personally I'm much less inclined to re-up with a C7 next year if it isn't significantly quieter than C6.

If it took another 50 pounds to make it so, I'd pay it. It would make the car a better daily driver and a much better GT. I know the idea of fifty pounds will bring on the rage, but that midrange noise muffles music and conversation and adds stress to long drives.

[x] GTS - Grand Touring package, includes cabin noise reduction, 9-speaker audio system, navigation system, and heated and cooled seats that still have good lateral support dammit

I'm with you all the way on this one, Jinx. Count me in as another Corvette touring enthusiast who would pay for that package.

That doesn't really work. Especially if you want to avoid permanent hearing damage.

If you look at the shape of the rear of the C6 coupe, it is almost a perfect funnel of road/exhaust noise from the back end to the driver and passenger. Hopefully just the new rear window/end shape will break up that noise a bit.

Michelin Tires on my C-6 Vert really reduced the noise level as compared to the Goodyears

I will just add 65 more pounds of Dynamat if that's the case.

What helped me reduce the sound level from the hatch area was to buy one of these then install a round plastic dowel through the front flap of the cargo cover to hold it down behind the partition when the windows were open. All told added about 1-1 1/2 pounds.

I have found that the convert C6 is far quieter than the C6 coupes so it appears it is the coupe design that is the main thing that greatly increases noise in a corvette's interior cabin area.

That is why I bought a vert over the coupe...

I'd be surprised if we don't receive active noise canceling though the new "improved" Bose system. With the microphones for the infotainment system, it would be pretty easy to reduce a lot of the unwanted noise. It's already being used in the Cadiallc and would add a minuscule cost to the sound system in the 'vette.

Interesting. I do believe you are right. Bose just announced it for the Buick this month (http://www.prweb.com/releases/2012/12/prweb10195615.htm)

And here is their web blurb promoting the feature to automakers: http://www.bose.com/controller?url=/...ations/asm.jsp

No way not on the highway. The C6 vert that my mom drives is way louder in the cockpit compared to my C6 coupe.

They've already done the biggest thing they could do, which is to toss the Crapyears in the trash. My ZR1 is waaaaaaay quieter than my Z06 was when it had the stock tires. If I ever buy another car whose OEM tire is a Goodyear, I will immediately throw them in the trash and put Michelins on it.

I've got Michelins -- still too much noise.

Of course whenever you get new tires, even the same kind, they'll be quieter than worn-out tires.

Yes the C6 is a noisy car. I am also hoping there is something in the new design that reduces noise. I replaced the GY tires with FS WO RF and they are a bit quieter but the noise is still there.
One time I had two comforters in the back of my 3rd gen Camaro sucking up all the noise and I couldn't believe the difference. It was like driving in silence. The 3rd gens also had a noise problem and I think its due to the hatch glass.
