Project sound insulation, Determined to get rid of some road noise Options

[GotToyota]

Alright guys, I decided to tackle a project similar to what a member on here did by getting rid of some noise with a carpeting material. I'm attempting the same thing, except with my door panels and rear panels. I went to Home Depot and bought a 6'x9' roll of carpet padding for $30, along with a can of 3M rubber and vinyl spray adhesive. I already tried to deaden the sound a bit by using some extra Dynamat I had, but it didn't help much at all. Spray the door panel on the areas where you will be placing the padding, then rip pieces to the size of your choice and place accordingly. WARNING: You might want to let these panels sit overnight, because the smell isn't too pleasant.

Pics of the materials:

After I get everything finished I'll let you guys know how well this worked. I spent $40 in materials with tax, so it would be a pretty cheap solution to getting rid of some exterior road noise. Not the prettiest solution, but I feel it should help out greatly.

-Matt

[GotToyota]

I put the interior back in and put the car to the test on the highway. I must say that it's almost silent now. I will still have some slight noise though due to the lowering and my 17's. I would say that it's VERY MUCH worth the $40. I will be using what I have left to put under my carpet whenever I get brave enough to pull it out.

sometimes cheap works better that expensive.

that foam absorbs the noise so well. Has anybody ever seen a quiet room? They use foam. I like that idea for my doors. will try it

It worked wonders on my panels. I also stuffed some in the paneling where the rear speakers go.

I'd like to put some under the carpet, how difficult is it to take out?

-Matt

[njccmd2002]

3 hour job.

1.5 to take out and 1.5 to put in

have to take the center console out, etc ill be painting mine very soon

cool idea, ill prob give it a try in the summer. how heavy is the material?

Not very, I'm sure overall it maybe added 6-7 lbs? The doors do feel slightly heavier.

[CaliJeff]

did you dynamat the plastic/leather door covers before putting on the carpet stuff?

[GotToyota]

did you dynamat the plastic/leather door covers before putting on the carpet stuff?

Yeah, but I did that nearly a year ago. It didn't do as well as I had hoped, but the padding FAR exceeded my expectations and I'd say it's better than Dynamat as well as more cost efficient.

[itssteve]

well what most people dont understand is that the dynamat doesnt act as a noise barrior like the padding does, the mat is to weigh down the pannels so the speakers and bass do not flex the pannel and it helps reduce distortion flexing.

[Galcobar]

Aye: dampening = weight, to reduce resonance and sympathetic vibration. Insulation = absorption, to reduce transmission.

The one that's popular on Corvette forums, which I'll do once my Focal door speakers come in, is duct insulation. It's a foam backed by foil, self-adhering. The idea is that the road noise is absorbed through the foam, what makes it through the foam bounces off the foil and is further absorbed in the foam. Frost King/Thermwell is the usual brand, carried at Lowes and Home Depot.

[CaliJeff]

that sound dampening spray is similar to the stuff they use at thte dealership that they spray underneath the cars and wheel areas to reduce noise. There is a Dynamat brand to.

Yeah my dad was telling me about underliner spray. I'd like to give that a try as well.

-Matt

[dagreat1]

one of my celicas is corked dyno matted and foam insulated. Don't hear much road noise, but I still hear that 3sgte. As for my St I'm going to see what I can go with about $50 worth of foam and $50 worth of cork.... it should be silent

[GriffGirl]

I've seen that underliner spray - it's available at most auto supply stores actually. It's like a black rubberizing spray that you coat the undercarriage of your car with. Dealerships charge like a few hundred dollars for it, but it's really like ten bucks for a can of it. Only thing is, you have to get your car up on a lift if you can, so you can de-grease it thoroughly before you apply the spray. The spray will also protect against rust (good for those who live where it snows and the roads are salted)

Great job with that carpet padding! I bought some foil-backed insulation stuff to put down under my carpet, but I won't have enough for the doors so I think I'll do what you did and make a little visit to Home Depot! I'm on 17s (and will be lowered soon) and I HATE the road noise!!!

[njccmd2002]

any updates on the carpet area. I have my carpet off and this is tempting me so much!!!!!

No, I'm just not going to do the carpet. I'm satisfied with how the other panels helped it, but I imagine the carpet would greatly help out as well.

-Matt

[GriffGirl]

Gosh, there's just all kinds of responses I can think of to that comment, but I'll keep them to myself since this is a "family" site. (talk about tempting though!)

Anyway I say do it! Get thee some carpet padding and line that b*tch! I'm stopping at HD tonight on my way home and doing it this weekend.

[GotToyota]

I might do my carpeting on Sunday if I feel like ripping everything out.

[njccmd2002]

Cool, will do.

[richee3]

Man, my dad does remodeling on houses and we have a TON of this stuff sitting around! I've never even thought about putting any in my car to deaden the noise. After I got my exterior the way I want it, I was going to start on the interior and my first project there is to kill the noise. I think I'll give this a try tonight or tomorrow, after I take some stuff off of my parts car

[mitchy]

finished doing the doors today, havent tested yet (still drying/ getting rid of the glue smell) but i tried it on and it sounded like more bassy (could be just me tho) ill be doing where the rear speakers go tommorrow thanks to this thread

[GriffGirl]

Well I put the foil-backed sound dampening stuff that I had under the passenger side of the carpet this weekend, and that alone has made an improvement. I'm still going to do the driver's side and the door panels. I don't expect all the road noise to go away, being on those 17s is a PITA for the noise, but I think it's gonna make a huge improvement!

[dagreat1]

imagen how i feel. I got 19's

[razor7]

I would be careful with that carpet padding. Remember that when it rains, you will get small amounts of water into your door panels. Just like how when you spill whine on a carpet, you can sometimes smell it later, the same may apply to this carpet padding. I'd hate going through all this work and then ending up with a mildew smell come winter time.

I have a few friends who work in commercial ducting, I'm going to talk to them and see if I can get a couple of rolls of the same stuff that second link talked about.

-TC

[Galcobar]

Putting the padding on the interior side of the weather barrier should be fine -- after all, this is the same area where you find wood and glued-on vinyl, the design has to keep water away. The water entering the door panel should be flowing through the inner panels of the door and kept in check by the weather barrier.

[dustin15brown]

sounds like a great idea.... I'm definitely looking into this when I go home

[GotToyota]

Has anyone else done this yet? I want to see others results!

[GriffGirl]

I posted a WTB ad on CL for some carpet pad remnants and have scored a roll that is apparently enough for a small room; I will be picking it up this week! Provided it's not raining next weekend (it's supposed to though) I'll be putting it in then. If it's not raining hard I'm puttin' it in anyway! I'll be using it on the insides of the door cards, under the driver's side carpet (I already did p/s) and under the hatch carpet. If I have enough left I will also put some behind the rear speakers, but probably not for another week or two.

Cool, let me know how it turns out.

I also rolled up some and shoved it in the rear speaker location. That, and the openings behind the rear hatch panels (where the jack goes, then the adjacent side).

-Matt

[GriffGirl]

Good thinking about those quarter panels in the hatch, I'll do that as well.

[GotToyota]

Yeah, I glued some to the back of the panels, as well as rolled some up and stuffed them in the openings. It works pretty well.

-Matt

[razor7]

Alright,
I'm going to use the insulation material this weekend (along with replacing some speakers). I'll be getting the driver and passenger doors, quarter panels, and the whole trunk done. I'll post another comment here saying whether it was worth the money or not. As it stands right now, It's a pain to even talk to someone when pulling 70+ on the freeway. The resonator hits a sweet spot where you just can't talk that well, though 90% of the noise is just road noise. I'll let you guys know.

-TC

[gt_driFFter]

Yeah, but I did that nearly a year ago. It didn't do as well as I had hoped, but the padding FAR exceeded my expectations and I'd say it's better than Dynamat as well as more cost efficient.

I'm sorry but the only way carpet foam > dynamat is when you have installed dynamat INCORRECTLY, which you have done! It is not supposed to go on your door panels, it is designed to adhere to the actual structures of the car (the door, and actual body of the car). Dynamat, when installed correctly will greatly reduce road noise, while cleaning up the sound.

You failed to realize that I did put it on the actual door. I just put the small amount of what I had left onto the door panel.

[GriffGirl]

Dynamat is also heavier - which for me, I couldn't care less about; however, it's pretty spendy and just not something I have the budget for. I would think Dynamat would be pretty good stuff too compared to carpet padding - in fact, of course it would be. But for the money, the padding is a very inexpensive alternative that's worth experimenting with.

my car is much quieter now and its very paddy, the floor, you can sleep on it . sorry no pics, at work. but i did it!

[GotToyota]

This weekend I'm definitely doing the backseat area, but I might have to consider doing under the carpet too.

-Matt

[RickJamesBish]

I'd rather get rid of all the annoying creaks and rattles that recently came up...

[njccmd2002]

threads are worthless with no pics...

[GotToyota]

Hey, I posted mine.

Looks great. How does it sound (or lack for that matter)?

[RickJamesBish]

WOW, that looks like ****loads of work. Nice job though.

I tried to do my own insulation improvement work last weekend, since my speakers rattle stuff in the doors. I pulled the panels off and more or less nothing is loose, there might be stuff in the doors themselves but I can't get to them without ripping off the moisture barrier and I don't wanna do that yet. Problem is, the moisture barrier vibrates with the speaker, causing this kind of crinkly noise that almost sounds like rattling, so I tried to tape it all down and improved on it a bit. Still annoying though.

[Ugglan]

love the pics...always good to see how you could do it....

[razor7]

Alright, so I finally got my celica done, and to be honest, it made a huge difference, but I think that doing the same work under the carpet would be 80% more effective. Here are some pictures to give you an idea of what I did.












The guy in the picture is my buddy Snoey. He was working on his '98 Civic EX, sick car, has a b16a2 imported from Japan that's pushing out 190-195hp N/A

Anyways, hope that helps some people. For those that notice, the front 8" speakers on both sides were blown, I replaced both of them, and am working on getting money for the rears.

Once I get some more time I plan to do the whole carpeted area as well. But, when I do that much work, I'll also be installing a 4 channel amp and re wiring some things, so it'll be a while before I get to it. Within the next couple of weeks, I plan on finishing up the trunk and rear seat sections.

Also, for those that are wondering, what I showed you was 2 full rolls of the frost king material. If you plan on doing any more then that, buy 3+. You barely need any for the doors, but it starts getting ridiculous once you start laying it down on bare metal.

I just got done putting foam padding in my door panels and under my carpet (front and back seats). I'm guessing I did something wrong, because the results are a little lackluster. Then again, my test drive lasted 3 minutes and one mile. I have yet to get it out on the highway and test it. Hopefully I'm wrong and it had made a difference, just not at 30 mph. I'll let you guys know.

EDIT: Never mind, I was cruising on the highway at 70 today, and it made a HUGE difference! It doesn't at lower speeds for some reason, but at highways speeds it made a definite dfference. I still have to do my rear quarter panels and trunk though.

This probably a really noob question ... so my 97 SX has factory sound deadening already ? I pulled my back seats out to remove dog hair out of the seats (total nightmare ) and noticed it wasn't bare metal i was looking at. Will I technically be able to pull off this carpet padding project if i were to stick it on top of the 'factory sound deadening' ?

[GotToyota]

Yes, you can stick it on top of the factory deadening.

[GotToyota]

I just finished up with adding some of my extra padding under the back seats as well as additional rolls in the rear speaker compartment, and another piece in the rear hatch (I already had a square under my carpet). I haven't taken a drive yet but I'll let you guys know how it goes.

-Matt

[GotToyota]

Alright, initial impression is WOW! The rear is dead quiet now, and the mid section is a bit quieter. The problem area is the doors, as the most noise is still coming from that area, as well as the front fender area. One day I'll tackle putting some rubber undercoating in the wells to deaden sound.

-Matt

[stephen_lee]

I used this stuff about a week ago under the carpet alone


Using that under the carpet made a pretty good change.. still kinda loud but a lot quieter.
i need to get the door panels and quarter panels done when i get more money, and then i'll do the carpet foam.
HOPEFULLY that'll make the celica a luxury car, in terms of sound..

[GotToyota]

How much did a roll of that stuff cost you?

[Culpable04]

I paid US$17.04 + tax per roll at Home Depot

[D-Man]

Did you fart in a closed garage?

[stephen_lee]

I paid US$17.04 + tax per roll at Home Depot

yeah it was around $14.00 without tax from home depot.

[97celiman]

whats the wyoming thing from? i would copy and paste the picture but im figuring out my new laptop and i really dont wanna deal with it

[GriffGirl]

It's a cut up moving blanket I think

[bmj67]

Is that foil and foam duct insulation waterproof? I like the sound proofing idea but I wouldn't want to risk the mold and mildew smell with the regular carpet padding if it were to get wet

[Galcobar]

I tested the duct insulation myself, and found it's not closed-cell foam, so it will soak up water. However, it seems to dry out well.

Keep in mind the Celica already came with a felt pad underneath the carpet, under the rear seats, and attached to the underside of the trunk carpet.

Only the 96+, wasn't it? I know sound insulation upgrades were added for 96+ so if I'm not mistaken, the 94-95 models didn't have that. Anybody care to shed some light on the matter for me?

My car is a '98 and has the padding under the carpet. Nonetheless, the extra padding I added helped out a lot. But since that was already there, the biggest difference came when I insulated the rear quarter panels behind the speakers and inside the trunk.

Yup,
Only on the '96+. The '94 and '95 (like myself) are stuck with no sound deadening at all. The mod to the doors made a noticeable difference, maybe 20% quieter, however the majority of the noise is coming from under the carpet/rear seats/trunk. I actually have the rolls to finish the rest of the car, but I've been putting it off (I'm going to wire up a 2 channel amp under the passenger sear, going to run the wires under the carpet. Used to power the 8" polks in the doors). It's one of those projects that I'll eventually get to.

However, I will update you all once it's done!

-TC

[Galcobar]

Guess the lack of underpad helps explain the lower weight of the early sixth-gens to the fifth-gens; I know every fifth-gen I've ever seen, including ST models, had the padding in all three areas I mentioned.

[razor7]

Alright guys,
Thought I'd finally finish the follow up. I've been sick the past few days, so I decided just to take a bunch of Tylenol and actually do something productive.

So For starters the whole process for getting the seats out, getting under the carpet, installing the foam, and getting it back together took about 3 hours. However, a good hour+ of that was spent working on my passenger seat which had coins stuck in the tracks... It wouldn't go forward, so getting to the back left (nearest the drive train) bolt was impossible till they were removed.


I am in a '94, and even though it looks like they used some sound deadening material... they didn't. The road noise was horrid, hence this install.







Once the passenger seat was taken out, everything went according to plan. I took it out for a quick test run, and I must say, For all of the '94-'95ers, DO THIS MOD! Just remember that I have under the carpet, in the door panels, under the rear seats, and the quarter panels done. It cut out so much road noise that it made driving more enjoyable then it already was. Since the resonator is right under the driver's seat, the noise that's generated by it is drastically cut. In fact, when you're low revving, engine noise is almost inaudible. However, if you give it a little bit of go, you can still hear that powerful 5sfe engine kick in

Very nice, thanks for your input Razor.

[Ugglan]

razor: what material did you use? Dynamat (spelling?) or some generic stuff, how thick is the material?
Looks really good, I'm planning to do this mod i the summers, don't got the time or money right now :S

[stephen_lee]

razor, how did you do the door panels and about how many rolls of duct insulation did you use? i only did under the carpet and rear seats and it took 2 rolls.

[razor7]

Guys,
Check page 3 for more photos and more info as to what I've used.

The material is called "Frost King Duct Isolation" The product was 1/8th in thick and is sticky on one side, and has foil on the other side. I believe there was a link on either page 1 or 2 that takes you to a page where a guy used the same material in his Z06. He came out with the same results that I did.

Also, the Frostking material was only $15 a roll. It took 3 rolls to do under the carpet, in the door panels, the quarter panels, and under the rear seats. I plan on doing a 4th roll which will be dedicated to the firewall (behind the dash) and the trunk. So for $45 you can have your car sound MUCH quieter on the freeways, and won't rattle as much (if you have subs). Definitely worth it in my opinion.

Exactly. So as for the foil-backed insulation stuff, you should be good to go with normal use. I'm using it in my car now, and haven't had any problems with it whatsoever, which says a lot considering I'm in the pacific northwest and the ridiculous amount of rain we get here in the winter.

Edit: I just read the rest of the thread. I've got a '94, with basically no OEM upgrade options like power windows or upgraded sound system, etc. but I DO have the STOCK sound deadening stuff beneath the carpet. So it's not true that all 94-95s came w/out it.

I believe the under carpet padding was added to all of the 6gcs regardless of year model. If you owned a newer 6GC you'd know what I was refering to. Sometime after the facelift [or perhaps at the same time I don't remember] they added additional more high tech sounddeadening in response to consumer complaints about the roadnoise in the 6GC. One item they added were these little plastic cubes similar to the underside of the cover of a dot matrix printer [If you can understand what I'm talking about right now you have great intuitive skillz - this is one of those things I can never explain properly without pics or outside assitance]. Ever owned a dot matrix printer? Those things were loud as sin right? The cover that goes over the top that is made of clear plastic - the underside of them were of a cubular sound deadening design. There were similar sound deadening devises added to the newer 6gc's rear body panels. I understand there were other upgrades to the sound deadening but I am unfamiliar with what those other upgrades were.

[RickJamesBish]

Are you talking about those cube things in the doors?

[DEATH]

Hadn't noticed them in the doors but I did notice them located next to the rear speakers - those are for sound deadening. Again - ever owned an old dot matrix printer? With the cover up for access the printer is loud as sin - close the printer while it's still printing and you notice a dramatic reduction in noise. Older theatres had a similar setup to reduce outside noise.
Again - supposedly this is just one of the things they did to reduce noise from outside the cabin.

[GriffGirl]

^He's too young to know what a dot matrix printer even is.

Okay I take back my post about having that stuff though, I didn't read all the way and thought the stuff under the carpet was the sound deadening stuff that supposedly didn't come in 94-95s.

[RickJamesBish]

That's true, they're also by the rear speakers.

[stephen_lee]

my 94 has factory sound deadening. felt under the carpet, a foot of felt by the rear speakers, and a vinyl/felt lining on the firewall....
it all sucks though aha

[stephen_lee]

update! today a lot was done.
foil/foam was put into the doors, rear panel, quarter panels(f&r), and floor.
carpet padding was added behind every interior piece and under the carpets.
spray glued padding was added to door panels, under cabin carpet, under hatch carpet, behind trim pieces around rear speakers, and trim pieces in thte hatch, including the hatch it self.

the drive:

City driving 0-40 was partially quieter, worth the cost of the foil.
highway driving 45-70 was substantially quieter. well worth the money/time put in.
i had to talk to myself to remind and compare how quiet it really was.

what still needs work:
1. Roof..
2. A-pillars
3. firewall
4. HVAC

This car is my daily, and i have another celica for project/fun driving, so i want this to be the most comfortable, yet kinda sporty, ride.

[richee3]

x2. It's definitely worth the money you can spend on this.

[stephen_lee]

Gravel roads are nearly silent now, too

[97celiman]

wait so when you say foil and foam...what are you talking about? i know the foam but what foil?

[Galcobar]

wait so when you say foil and foam...what are you talking about? i know the foam but what foil?

Read over the earlier pages in the thread.

[97celiman]

right so that was the foil you could buy that was self adhesive? i guess the better question would be, what order did you do this in? foil and foam wise?

[stephen_lee]

i did the foil/foam duct insulation first, then the carpet padding ontop

the foil/foam is one piece. its adhesive/foam/foil for the duck insulation.
i put this directly on the sheet metal
then i put the carpet padding on the trim pieces and carpet directly w/ spray on trim adhesive

I wish oi had a camera to take some pictures
next time i have my interior out ill borrow a cam and load up some pics

[mariosdarkworld]

So did anyone do the roof yet? I did my roof only and that did alot for me. Prolly try n do the rest sometime.

[Harold_Fastwaker]

So did anyone do the roof yet? I did my roof only and that did alot for me. Prolly try n do the rest sometime.

I did everything but my headliner and firewall. Those are next some point in the next week.

You did not have any issues getting the headliner back on with a layer of frost king? I was slightly worried that it would not want to mount back up.

So did anyone do the roof yet? I did my roof only and that did alot for me. Prolly try n do the rest sometime.

I did everything but my headliner and firewall. Those are next some point in the next week.

x2. I want to do the headliner, but I'm afraid of fitment (plus if I'm removing it, I might as well find one in black to replace it with). If anyone has done this, please chime in.

i've done it. yes it is quite hard to get the visors to mount right w/ the layer of frost king, but with enough force, they go in. thats the only fitment issue i had afterwards. its nice to have a silent interior

noted, then I may just not put a layer underneath those two small areas.

I put the interior back in and put the car to the test on the highway. I must say that it's almost silent now. I will still have some slight noise though due to the lowering and my 17's. I would say that it's VERY MUCH worth the $40. I will be using what I have left to put under my carpet whenever I get brave enough to pull it out.

Did you mainly do this just to reduce road noise, or did you also have unwated vibrations in the doors? I have a lot of little vibrations that are coming from the inside door panel and I'm wondering if this would help reduce them.

[Culpable04]

the vibration from inside the door can be fixed by tighting the glass. take your door panel off and use the service holes to tighten the nuts that hold the glass, that will take care of most of the noise or all of it, depending if you have anything else lose in the door area.

What about doing the roof with a sunroof? Anyone done that one yet?

I did mine today, with a stock sun roof. It is moot, I didn't really notice too much of a change.

Thanks, I probably won't bother then. Toyota makes some noisy sunroofs. I wonder how much quieter my car would be without it, but I'd rather have it.
