How to reduce road, traffic and tire noises ??
Good morning everyone
Iīm 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 canīt 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.Itīs 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 wouldnīt 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 ! FEA-EN |
I find that because the car itself is so quiet, it's much easier to hear outside sounds/noise. (though in a way this sounds a bit contradictory)
I'm pretty anal 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.. |
Sorry to hear about your issues. Hope you find a solution soon.
Which country are you located in? Is S212, the same as W212...? |

I think Dbldpr on here lined his car with sound deadening material for this very reason. Maybe he can chime in on what he used.

Thanks for the clarification. Doesn't it seem odd that may be the S and W are improperly placed semantically at least S212 for Sedan and W212 for Wagon. :D.

I lined the trunk area where spare tire sets with sound deadening material sticky one side and foil on the other. Also took panels off underside and lined the bottom of car with same material and undercoated the panels. Dealer says the mechanics that have driven the car say it is the quietest car they have ever driven. Made a big improvement it preventing outside noise.

I have the sedan but did the same thing. I lined the bottom of the trunk, under the spare tire with dynamat. This quieted the inside of the car significantly. I also read than another member, removed the wheel liners under the wheel arches, installed dynamat there, then reinstalled the wheel liners to block even more road noise. (Dynamat is the brand name of a sound deadening material sticky on one side, foil on the other.)

I installed dynamat sound deadening materials on my both my front doors, rear upper trunk deck and the trunk while upgrading my sound system. Definitely could tell the difference.

To really get a quieter car you would have to get something else, probably not of European origin.
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, thatīs 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:
Iīm really surprised when your dealer issaying itīs 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 |

Thanks a lot, dbldpr!
Last question: Can you please name the material you have used? Greetings from Norway, Eugene |

Thanks, thatīs what we call Alubutyl (ABX) in Europe. Problem with ABX, once added, never ever removable :eek:
I start with some smart tests on the panel. Hopefully I reach the same noise level as you have.. EN |

Agree.
What is your impression before and after? Is it much quieter now? |

You make me curious. I try it out and give feedback when Iīm ready.
If I have a 10th (!!) of the noise, I spend a beer :y Thanks, Eugene |
