Sound deadening...

[BlackTigers]

I drive a Sexcort. It's sexy, and i have very loud speakers in it, but I don't always blast music, and when im not, my car is loud.

Very loud, annoyingly loud. There's a lot of interior rattles, road noise is a bitch, and wind noise, traffic noise...every noise is terrible.

I was looking at how to help get rid of the noise, but it's an Escort so I know it won't all be gone. Mainly, what do you guys suggest?

I've head that using some CLD tiles to reduce vibrations is a good first step, and then coating everything in some closed cell foam is what blocks outside noise pretty well. Am I right in my thinking here?

What would I do about trim vibrations? If I just....covered the backsides of the trim pieces in felt or foam....would that work?

If you can take apart your car, buy some sound deadening foam (same stuff is used in computers and cars, aka dynamat and whatever) and start sticking it everywhere it won't melt.

Putting in foam will work if it keeps the parts from moving relative to one another once they are installed.

It'd cost $900 to coat my car in dynamat "in places where it wont melt."

I know there's more efficient ways to do this than Dynamat, and dynamat will weigh a shit ton.

Maybe $100 at most.

that is not even comparable to the type of product that dynamat is, though.

that's a foam, dynamat is more of a CLD tile designed to reduce vibrations and resonance.

Hmm i suppose if you have a lot rattles, CLD will help. That doesn't get rid of the noise coming in though, just the noise being made BY your car.

The squeaks and rattles are easy - newer cars just use those little felt stick-on things you'll find in every hardware store for $.99 for cupboard doors (so they don't back when they close). Put them in between all the components that touch.

I don't really think you're going to be able to quiet it down that much otherwise. I suspect you'll be unhappy with the results. Quiet cars have it designed into them - from the intake dimensions to the cavities on the block to the internal structure of the frame etc etc etc. Those aren't things that you can really do to your vehicle. Even stuffing foam in the door panels and under the dash isn't going to quiet the wind noise, engine noise, and noise from passing cars.

Follow this guy's instructions and it will make a huge difference. A roll of his mat is more than enough for the average car (assuming you do doors with 2 layers and the truck floor/walls. The ensolite foam is what really helps kill the noise. Highly recommended.

Naturally it won't make your car as quiet as a Mercedes but its a decent start. When you want to get serious, rip out the interior and cover the floor, firewall and roof with both components. The results will surprise you. And, its really not all that heavy.

I skimmed the thread, but what about a liquid-applied sound deadener? Check out elemental designs stuff. http://www.edesignaudio.com/index.php?cPath=1_24

Foam itself won't deaden shit. Liquid deadener is not really that effective; you can do much better for your $$$.

Read through this site: http://www.sounddeadenershowdown.com/cgi-bin/index.cgi The owner, Don, has put together a great site which explains what will actually work in lowering road noise in a car and why. The products he sells are all I've installed in my car and have had great results.

CLD + CCF + MLVb

Got it, thanks. Out of curiosity, how much did you end up spending to do your car?

I drive a Sexcort. It's sexy

:hmm:

Sounds like a viable solution.

To be honest, I can't remember; it's been quite a while.

Do you have a budget and how much work are you currently planning?

When I did my lexus I did all 4 doors, rear deck and trunk lid. Since the car is already well insulated my main concern was just deadening the sheet metal for my audio system. The results were great and well worth the time and money (~$120).

pull everything down to metal, line the whole cab with it and put everything back in. should be quiet as hell after that hehe.


edit: damn, beat to the punch...

My budget is I want to be efficient. That is, if $150 produces 95% of the deadening of a $250 install.... I'm not going to spend the $250.

I can rip out my interior and put it back together in a bout an hour, so the work part doesn't concern me.

Check out how good the blocker is on your firewall.

Personally I'd use blocker in inner door skin (this will also create a baffle for your speaker and will likely yield much better bass response if you have your midbasses mounted in the door.), under the carpet in the cabin, and around your wheel wells. Tossing a couple CLD panels on your roof will help depending on design. If you do not have sub in the trunk, I'd block/seal the rear deck and maybe back of your rear seat.

I've used that stuff throughout my car: doors, cargo area, floor, and roof. It does work to reduce panel resonances (same function as CLD tiles) if you apply enough layers. The problem with the liquid stuff is that it is difficult and time-consuming to apply. You have to wait a while for each layer to dry and it doesn't seem to work unless you put on several layers and cover the whole surface with the stuff. Looking back, I could have saved a lot of time and some money by going with the CLD tiles. Unfortunately, I was unaware of their existence at the time.
