Has anyone actually undercoated their undercarriage or wheel wheels to drive the roadhouse that is part of highway driving? I know your tire selection has a lot to do with road noise I'm curious of real world experience with the aftermarket sound deadeners, you know the stiff then looks like black tar that they spray under the car and in the wheel wells

I have dynamat in all of my doors but it didn't do anything for road noise, helped with the audio quality though.

Has anyone noticed any difference between the 09-10 model years and the 11-14 models. Acura added noise deading material and thicker door glass and different windshield starting with 2011 model. Hondas and Acura's have all ways had road noise as a complaint .

It must have made a difference because in my 2012 SE I barely notice the road noise.

Not the Dynamat however
I put different noise proofing materials on all of my door panels, trunk, backside of the rear seats, and feels like just little bit quiter...?
Now actually, I don't know the difference....

I'm curious about this as well...what options have you guys considered or have actually done? I have a 2013 TSX and the road noise at highway speeds is very intrusive. Any phone conversation I have on the HandsfreeLink while on the freeway, callers always ask if my windows are down (they aren't).

Maybe it is the tires or something. My 2012 TSX SE is very quite on the interstate. BTW, Dynamat Butyl/Aluminum works to stop metal from resonating. Great for car audio, not a lot of help for road noise. If you want to help with road noise, you would want to look into mass loaded vinyl for horizontal surfaces and use the butyl/aluminum products for vertical surfaces, especially the doors.

How did you get it inside the backs of the rear seats? i cant figure out how to get it off.

Mr. TTL

That may be an issue with the HandsfreeLink. My 2012 SE is pretty quiet on the road but I sometimes get the same comment from people I call.

TurboJunkie

That's definitely a possibility, just earlier today I had a caller say it sounds like my windows are down. IMO its a combination of both...coming from my previous cars (all German) the road noise in the TSX is considerably louder, but I still enjoy the drive!

Update: I've been reading on a few other boards that people effectively reduced road/tire noise by using 3M rubberized undercoating on their wheel wells...Although not designed specifically for this purpose, I read that it does have this effect as a byproduct. I might give this a try on my spare time.

Newer TSX's thicker class works so well.
I want to change all my windows to newer one..

I hear plenty of road noise on my 2010.

I sprayed undercoating under the car and in the wheel wells when I got the car new, so I can't compare before/after. I did remove the various plastic and metal shields from underneath and in the fenders before i applied the undercoating to ensure that I actually was coating the body.
My main goal was rustproofing and was hoping to get some additional sound deadening. However, I find my 2010 V6 not as quiet as I would like it. Even the later addition of some dunamat on the rear shelf and under the rear seats made no noticeable difference.

What neibur recommended is what I did in my 3G TL. I used MLV in the doors, and floors with "some" vibration dampening material (around 25% coverage on all the flat spots) and I think it made a huge difference in reducing the road noise. I done this for my audio build, but I would do it again if I were experiencing road noise in any other car.


I lined the doors, floors, and roof with the MLV. Sound deadened the trunk and used what vinyl I had left over on the trunk floor. Was around $500 for everything I used but im sure most people could get away spending less, but again, I was doing it for sound quality. The reduced road noise was an added bonus

I always undercoat my cars both for the harsh winters and road salt in Canada and because it really does deaden road noise. I had a 09, 10, and 12 TSX.

cammy5

How much did you undercoat and what was the approximate cost?
