Cabin Noise

Our Grand Cherokee is definitely more quiet than the Q7. But the Q7 is more quiet than my X5. I’d say the Q’s about average. I know that US models don’t have acoustic glass which is really strange and doesn’t help it’s case in being the most quiet out there.

C&D rated interior cabin noise for the 2018 Grand Cherokee (2 models) at 66 and 69 dBA respectively; 2017 Audi Q7 at 64 dBA (keeping in mind that dBA are measured on a logarithmic scale, with a 6 dBA increase representing approximately twice the sound pressure).

Cabin Noise
Hi all. [2017 Q7 with 20" wheels]
Many of the roads here in Virginia can be pretty rough, versus a real smooth road. You can tell the difference when you drive on them. I live in Culpeper where the main north/ south highway (15/29) only has a few smooth spots. I believe they use a rough based road to help with long term longevity, as in, does not require to be repaved so often. (can't find the correct word here in my Monday morning mind ) The pavement in the Town of Culpeper uses very smooth pavement and I can barely hear the tire noise.
I did find that the Continental Crosscontact LX Sport wheels replacements for the GY Eagle Sport (RF's) helped considerably but I still have what I consider annoying cabin noise.
I know the windshield was replaced with all the correct rain sensor's (etc) included but wondering if the glass may not have been OEM, as in the correct specs to help with cabin noise issues. I've read some posts about how expensive it is to replace OEM windshields replaced.
Your thoughts would be greatly appreciated.
Regards,
Charle

US Q7’s are not equipped with glass to help with cabin noise issues so you can put your mind at ease. Besides, your road noise concern would have nothing to do with your windshield. The Q7 just isn’t as quiet as people convince themselves of. I could see why they’re in denial, though. After paying a premium from an Audi, and most are in leases which we all know are a horrible deal from AOA. Love my Q7, but it’s only average in most regards.

Thanks. Agree with you. I love the power but the cabin noise is an issue. I got a really nice 2017 Q7, Premium Plus with loads of packages/options amounting to $14,860. Base of 55,550, total price of 70,360. (Glacier white metallic/pistachio beige) with 15K miles and I paid $50K. (paid cash)
When I test drove it I thought most of the noise was tire/road noise but after replacing the tires I still have annoying cabin noise. I had a 2013 Infiniti JX-35 with Michelin's that was so quiet. All the rave reviews for the Q7 but in my view way overrated!
Thanks.

As with audio quality, noise can be very subjective. Yes, run flats can be very noisy under correct conditions, and yes that noise will penetrate into the cabin and worse into your scull. Windshield comes to play when you talk about wind noise, but at that point we could also be talking about sunroof, side windows and mirrors and whole bunch of other things. I have to disagree with sickk23, I find Q7 pretty quiet. Find yourself a good paved road, get it to at least 80MPH and see if you can have a quiet conversation with your spouse/girlfriend/boyfriend/dog etc. This may not be realistic for most of us during everyday life - I know it is not, for me on Long Island NY - and that's why we may occasionally feel that the vehicle should be much quieter. However, if you do mange to find a good road and you find that the tire noise or wind noise is overbearing, then I would say, somethings wrong with your vehicle.
Just as a side note, I took the Q7 on a coast-2-coast road trip, and I do have to say that there are many places where the asphalt is less than kind to the tires and the noise level. However, long stretches of nice paved roads can be very deceiving, there is very little difference in noise level between 70MPH and 110MPH :-) The only other vehicle that behaved similar (well, actually a bit better) was MB GL450, so that's actually saying something.
BTW, I do not recommend you try going 80MPH in Virginia, not worth the felony charge.

C&D is the only outfit that I have seen that does objective testing. They used the same course, the same testing equipment, in the same location in the cars. What the tests signified was that Car A, equipped as noted (usually with specific factory options), had X noise level, compared to Car B, again with options as noted, with Y noise level. That's it. It allows objective comparisons for car shoppers. Your car, with non-run flat tires, on a smooth Interstate, no traffic, at 40 mph, may indeed be quieter than another model that C&D rated quieter in terms of dBA. But they didn't test your car, on their track, at their speed, at that time of day. So the argument that car model A is quieter than car model B is really invalid, scientifically, unless you are very specific. An example would be comparing the models tested in the 2018 Audi review: the Volvo that C&D tested produced more cabin noise than the Q7 they tested, as configured. A reader might extrapolate that all Volvo XC90s are noisier than all Q7s, which might be valid for similarly equipped cars, but maybe only under the conditions specified. It only provides a starting point for comparisons, but is certainly more objective than saying I believe my Chevy is quieter than your Ford. How's your hearing? Where do you drive? What kind of tires? Much traffic? How's the road? Engines? Options? Time of day? Just like reading a peer-reviewed journal, specifics matter.
