^^ Just got a ride in a new Corvette this morning. Although the owner had installed loud aftermarket pipes, and we drove fast, the car was surprisingly quiet. One thing I noticed in particular is how little road and tire noise is transmitted to the cabin’s interior.

So what is the difference? It is simply that GM uses custom sound deadening that is slim and lightweight, but customized to the car’s dimensions. GM tests the results insuring that it works as a sound deadening solution.

BUT, look at the demographics that buy the cars (corvettes).... older men. they want quiet and refined, my ls7 with long tubes, and hfc's is quieter than my 350 was

**edit, don't forget cost.... the vette cost a helluva lot more than the nissan brand new, i bet a lot more goes into design with comfort in mind

I'm going try to do it once the weather warms up. It'll probably take me weeks to get it done since its my only car though.
What have you done to your car may i ask ?

^^ I installed sound deadening in the front doors, but that was more to improve sound transmission from my door speakers than mitigating road noise entering the car’s cabin. It significantly improved speaker performance, and the project also reduced road noise (but this was minimal).

I also installed sound deadening on the rear hatch floor. It helped, but was disappointing as a solution.

I think a lot of the road noise enters the cabin through the wheel wells. I cannot offer any statistical or comparative data or an explanation that supports this. It’s only my best guess/hunch.

I did deadened the trunk in my 350Z and added soundabsorbing mats. Conclusion? Don't do it. It's not worth it.
