Sound Deadening

Hey guys. I have a 06 Ford Escape Hybrid and I am looking to do some sound deadening on it. I really don't have much experience in this area and hoping someone could make a recommendation on where to start/good but not too $$$ products.



I am not looking to win an audiophile competition, just make the interior a bit quieter.
 
Since it is a pretty new car the stock sound-deadening material should be in relatively good shape.

Are you looking to decrease road noise from the undercarriage i.e. wheel/tire noise? or noise that is coming into the car from other drivers/automobiles on the road?



I have always had good experiences with Dynamat, which by itself is not ridiculously expensive, however the cost to have it installed can be significant. If this is something that you are going to do yourself you could probably pull it off on a budget. However it has been some time since I attemtped to sound deaden a car so the prices might have changed.
 
Pay somebody? It's easy as peel and stick.



If you go to ebay you can pick up a Dynamat Xtreme bulk pack for around $100.

Secondskinaudio.com with their Damplifier is also great.

Cheaper solutions would be Fatman, Edead, Peel&Seal...



It's really not that hard to do. But as LastDetail said, figure out what you want to quiet down first.

On the contrary, most OEM damping material is crap compared to just about anything available to the consumer. At work, we use Hushmat, but it's comparable to Dynamat. If you remove your door panels you will see a sheet of plastic which is more or less a dust barrier. If you remove the plastic sheet and replace it with Hushmat, Dynamat or any other product listed above, you will notice a huge reduction in road noise. Cover as much as you can. Get a grease pencil and trace your door panel on the door. Then when you remove the panel you will see where your "boundary" is. You don't want to see any damping when the panel is on.
 
There's a good video on Crutchfield on how to install it in doors. I am going to tackle this project in the spring on both my Ridgeline & my wife's RSX-S - both have tons of road noise.
 
if your on a budget, i suggest using eDead sound deadening, in the eDead line they have a closed cell foam that blocks higher frequencies like road noise. I have had nothing but great results with it. you can also pick up some Jute or something like it at home depot or lowes, which is just like carpet padding. it is already under the carpet on almost every vehicle, but you can add it other places and it really helps!
 
RAAMaudio - Quality and Value in Automotive Sound Deadening

Cheaper and better than Dynamat (Yes, I've used both) Get Some RaamMat and Ensolite foam, a few cans of his spray adhesive and you are good to go.

He has also got a good "How To" section, read through that. Its really not that hard to do, if you are comfortable popping off panels and pulling up carpet (Should be pretty easy on most vehicles)

Good luck!

I have heard good things about "Brown Bread" as well. I would be doing the install myself...seems pretty straight forward, just time consuming.



I guess I am looking to make the overall cabin quieter. The noise from the engine is not really noticible, more road noise.
 
Has anyone used this "Spray Undercoating with Sound Block"? I think it is made by duplicolor.



I heard that people use it in their wheel-wells...don't know how that comes out. I am sure it does some to protect the undercarriage.
 
I have a friend with a 97 Supra that he has been cleaning up, and to assist with the sound deadening we put quilt batting behind all the removable panels in the doors and rear hatch area. Basically anywhere we could stuff it we stuffed it. That car is way quiet inside now. His goal wasn't really to kill all the sound. It was just to assist in cutting down the sound without spending a ton of money on something that wasn't really a top priority.
 
Do you buy Monster brand home theater cables? Do you own and love Bose products for the price you paid? If you do, buy DYNAMAT!



Seriously though, DYNAMAT works, but it's the most overpriced product in its class.



Cabin noise you hear in your car is from two main sources... audible noise from tires, wind, and your engine, and secondly from chassis vibrations that resonate into audible sound.



To eliminate the vibrations...butyl tar-based dynamat adds mass to the resonanting/vibrating sheetmetal it's applied to and absorbs the energy converting it into low level heat.



To eliminate engine, wind, and tire noise, you can add dynamat to the interior firewall, interior wheel wells, and doors which will be effective to a point... but even better would be to use dynamat in addition to a "barrier" type noise suppresor.



Read the stuff on b-quiet.com. They sell brown bread, which I bought 3 years ago and used on my doors and trunk, but I plan on saving even more money this spring when I buy their v-comp foam cell barrier material and use it with HOME DEPOT-bought "Peel n' Seal" tar-based roofing adhesive material (on my entire interior floor, firewall, and rear wheel wells), which on many car audio forums people have used which is nearly as effective as more expensive dynamat/brown bread.



The Peel n Seal is about 1/3 the price of brown bread per sq. foot, and Brown Bread is about 1/2 price of Dynamat. I'm puling those numbers out of my *** but if you do the shopping you'll see I'm not that far off.

+1 for RaamMat. Best bang for your buck. Very easy to work with. The owner of the company is a great guy, and will give you help if you need it. I applied RaamMat and Ensolite to my entire interior. Check my CarDomain for pics. http://www.cardomain.com/ride/832238/10
 
I am about to install one of these products in my '95 Formula to reduce noise, specifically some vibrations that I am getting in the rear sail panels from bass coming from the speakers.



Just be aware that with all of these products, if you find the need to remove them later, it can be a major hassle.

I completely agree with this post(especially about the Bose part). I used Peel/Seal on my '97 Bonneville on the trunk floor/walls, and under the backseat and just that little bit alone made it sooo much quieter. When I sold I kinda "borrowed" the stock sound padding it came with out of it, and left the Peel/Seal in(it is permanet). I still have it waiting to be put in the Aurora alone with a coat of Peel/Seal.



Edit.... So i brought up a really old thread... Sry :-)

Removal isn't all thet bad ... Heat gun will peel it pretty easy ...



The Spray on liner works very well some people (me included) have used spray in bedliner....

I've used Rockford Fosgate Noise killer spray in liner as well
 
i would suggest beware of mounting large sheets vertically. Sometimes its own weight can help it to fall off where you applied it, especially in extreme weather. Just cut it into smaller pieces for doors and such...
 
Tar based stuff is OK for horizontal surfaces but buy butyl rubber based deadeners for the vertical. Tar based has a very low point at which it starts to become semi liquid, losing grip on the panels after that. It also can in some casers have a strong tar smell for quite a while. Google sound deadener showdown for a comparison on butyl vs tar. Deadener simply makes the panel quieter by maiking it heavier, reducing resonance or "ring". A pebble kicked up would only make a dull "thud" rather than a "ping". For noise reduction I would suggest the ensolite as mentioned earlier or the eDead (Elemental Designs) teklite which will deaden actual sound better than a mat. Use this inside door panels, under carpet etc and use the butyl mat on any surface that "rings" when knocked on with a knuckle.



A cheaper alternative to ensolite or teklite but which doesnt work as well is synthetic carpet padding that looks like it is made of felt peices. Home Depot or Lowes carriesd it cheap. This is the stuff that looks like it came from under a piece of auto carpeting. You can buy this and then use 3m adhesive to place an extra layer or two under the back seat, under the carpeting under the front seats and under the trunk carpeting. Kinda bulky to add everwhere and not recommended in the doors or anywhere that moisture may be as it is not a robust material.



Good luck
 
...Another one for RaamMat I have it on my doors, made a very nice difference with one layer on the inside and outside panels. I also have Dynamat Extreme in my trunk, which I was VERY impressed with, but I don't have no where as much bass in my doors. I would stick with RaamMat for price and service, Rick anwsers my e-mails before I can even go check my mail again lol.
