Wind noise - how much of it do you hear?

[retired99]

Well, I have a brand new C7, built in September. The noise is not terrible, but it's not as quiet as I hoped for also. I have a very sensitive hearing and from around 50 mph i start to hear some 'air flow roar', seems to be coming from the mirror area. As the speed increases it gets louder. It felt less noticable in my Passat CC, but also maybe because of more engine/tire noise.

My question is: What do you hear most at let's say 50-70 mph (with the radio off)? Is it the tire noise, the engine or the 'air/wind'?

Ps. Im often covering up to 1200 km through German highways at speeds of 100 mph +, so accustic comfort is very important for me

50 to 70 it's tyre noise, although this varies a lot according to the road surface. Above 100mph it's probably wind noise although at this speed the sounds seem to merge. I drive in Germany quite often and it's quiet enough at 100mph plus although not exceptional. Better than a BMW 5 series (F11) and not so good as a MB GL, my previous two cars.

My car is an A6 Allroad Biturbo on 18" wheels.
