How to reduce road, traffic and tire noises ??
I´m new in this forumand try to figure out how to reduce the „excessive“ road, traffic and tirenoises which end up in my cabin..
My car is a 2015Facelift S212 with a 2L petrol engine.
Do you know one of thefollowing situations?
When passing a truck ona motorway, the noise from the truck which is guided into the cabin is reallyloud. I can´t listen to the radio during that time..
Same situation when waitingat a traffic light. The noises from the crossing traffic are very loud. Itfeels like if there is no insulation material installed.
Additionally, I noticeall tire noises from cars driving in front of me. Even if they are 200m away.It´s similar to a fizzle, like a door is not completely closed and the wind blowsinto the clearance between door frame and door leaf...
I already checked allseals, tapped several gaps of the body, adjusted the doors, also addedadditional seals to some locations, etc etc. No significant change observed. Itseems my car is really bad insulated to noises which come from the front and especiallyfrom the side. I wouldn´t say my problems are based on wind noises, because whendriving alone on a motorway the overall noises are acceptable..
Out of this, I haveseveral questions to you:
Do you have similarproblems observed? Is there already a solution for one of the mentionedproblems available? I do not have acoustic glasses, but retrofitting should bepossible. Anyone any experience with that? Brings this a big influence? Hasanyone any idea what else I can do to reduce the cabin noises? To be honest, Iexpected a much better insulation from a Mercedes E-class…
Thanks a lot !

I'm pretty **** when it comes to sounds (a loose dashboard, wind noise...), but that also means that he more I focus on (what i think is) a problem, the bigger the problem gets..

Asian cars ride much quieter when you get into the luxury or near luxury field. German cars tend to be noisier because engineers equate noise to performance.
Another factor is that there is less soundproofing because it adds weight.
If it has Michellin tires, that's another problem.
If it has low profile tires, that's another problem.
A lot of the tire noise is coming from the wheel wells.

Hi dbldpr,
that´s interesting. Can you please explaina little bit how you have lined the bottom of your car? Where have you addedthe sound deadening material? Do you have any pictures?
Here is a list of what I have alreadydone:
- I already damped the trunk of my wagonwith Alubutyl and Reckhorn insulating fleece.
- I damped all wheelhouses from the outside alsowith Alubutyl and in addition a water resistant acoustic absorption material.
- I changed from 17” to 16” tires.
I´m really surprised when your dealer issaying it´s the quietest car he has ever driven… maybe the key for silence isto insulate the bottom of the car. As I said, some more information would begreat.
Thanks,
Eugene

I start with some smart tests on the panel. Hopefully I reach the same noise level as you have..
