Road noise reduction

[Incredibr0]

Anybody else' CB sound like a wind tunnel when you're cruising on the freeway with the windows up. It's hella hard to talk and even listen to music. I've been looking at options to sound deadening the inside of my car. Mainly because I want it to be a little less loud when driving and because my girlfriend says that it hurts her ears.

I am planning on using butyl rubber weather stripping from home depot that looks and performs similar to dynamat. Gas anyone used this stuff before or have any other noise reduction techniques?

There are large, flat surfaces on these cars that make a lot of noise. Surfaces like the roof, hood, door skins, quarter panels and trunk all make for a noisy car. You can use Dynamat or a similar product on the insides of those surfaces to quiet things down quite a bit. Also, carpet padding for significant than what we have would do wonders. I plan on trying to fit the carpet from my 3.2CL in my Accord when I have the room to bring the Accord out of the garage.

There's also a company called Lizard Skin that offers a spray-on solution that is said to work amazingly. It's detailed in this video by a guy who does some really awesome videos.

I just bought about 70 sq ft of Knukonceptz Kno-Knoise Kolossus. Just a hint, these style products reduce panel vibration. They do not block noise transmission. To do that, you need a barrier product. Mass loaded vinyl is popular in the hot rod and car audio community. 3M Thinsulate also has noise blocking properties as well as thermal insulating properties.

Also Peel n Seal works...just not as good as a dedicated CLD product. I have to find the comparison thread...found it: http://www.diymobileaudio.com/forum/...d-testing.html Very good and scientific comparison.

May pay to jack your car up and check your wheel bearings, They can make a very bad "road noise" like sound when they have failed

I had my interior stripped down to nothing for some time with no panels, or factory sound deadening. I put some fat mat rattle trap which is the 80 mil thick product inside the door skins, under driver and passenger floor panel, quarter panels, and a few peices under the rear deck. The interior of the car is going back together now, however i notice some difference already driving around. I'm contemplating adding more, Its not a night and day difference but it helps, its cheaper than dynamat, and it doesnt smell like tar give it a try.

i put peel and seal all on the inside of my doors in my cl type-s. man it made such a huge difference. i really want to tear dash and entire interior out and do the whole car.

carpet padding is a great Idea, i was planning on doing that as well but wasnt sure if that was a good way to do it or not. LIzard skin looks great! though, it is quite expensive making it a little out of my budget for this mod.

I wonder if doing layers of peel and seal would work with a layer of carpet padding over the top of it. after looking at the Lowe's website (Home Depot discontinued their roof weather sealing tape) looks like Peel and Seal is what I would be buying.

Sorry I think I may have said the wrong thing (or incorporated what I hear as something it's not) The road noise i was talking about is just the loud noise the car makes from wind passing over it, primarily on the freeway. The noise isnt really there when doing anything less than 50.

Thats the plan for me too, inside the doors, take out the interior and do the floor and the roof.

Overall how much does it help do you think? I think probably 2 layers then some carpet padding or something to deaden noise would be what im going to do. if I can block as much noise from OUTSIDE the car that would be awesome.

..... It's hella hard to talk and even listen to music. ....

Sound dampening etc. will not help you here as this is not how the car originally was. Sounds like your door grommets are gone and thus you hear wind noise (and road noise) now. These are the seals that go around the door, around the window, inside and out, etc. Older cars have these issue and the symptoms are it sounding like you didn't roll the window all the way. I would change these first. Sometimes pulling on the door when driving on the highway can assist in finding the problem area.

Do you mean the weather stripping that closes the seal around the door?

Also i know the window rails need to be replaced. My window shakes when I close it. (I have a coupe) so I'm sure this is probably a problem area for sure.

Yes, that is what I mean. Window shaking when closing implies the guides are gone too (or not smooth).

[Rilas]

Actually on the coupes the lower half of the guide and rail can fall off. Both of mine were laying in the bottom of the doors. Causing all that much more rattling. Although some of the rattle can come from loose window pins in the coupes.

You can get that roof in stuff from homedepot that's like black tar with foil on it for cheap. Does the same thing as sound deadening stuff. That with carpet padding would work pretty well.

It helps, but it will not turn your car into a new lexus as far as a luxurious quiet ride is concerned. But all the things combined will make an improvement For sure.

Yea i definitely do not expect that lol just something that will make it a little less noisy inside the cabin. It would cost far too much to make it that quiet, and I actually still want to hear the car

The worst is when the gaps get so big that on windy days it pulls the car side to side and there's a large sucking noise coming from the window. Got so loud on cars I've had in the past that you can't hear anything else.
