Just take some picture of simple installation for car deadening to share. Hope it can solve your curiosity.

Toyota Vios 04 entry level door dampening

Door panel taken out, you see the contents inside, ori spk, weather sheet, door handle, cable and etc.


Take the weather shield off, then you will see the bare metal door frame. that's the part you need to dampen.


Most of the car comes with extra anti-rust grease applied, wipe it off by using spirit. (buy at h/w shop)


Wipe it off and here's the bare metal, dun worry about rusting, your oem base paint is a very good anti-rust protection paint with full metal coverage


Do the same to the other parts of the metal frame.


The cleaned door frame now ready to be dampen.


Take a closer look inside the door frame, then get a ruler to get the measurement and cut out the dampening material to fit nicely.


You can use a glove when you apply the dampening material, but a tool like this is very helpful and cheap. Use the rear part of the screw driver to roll and press ont he dampening material, it should provide you better pressure to stick the dampening material on the metal.


After you correctly apply the material, it should look something like this, or even smoother


Next, do the part which is necessary, in this case, the metal that flex will be the only necessary parts.

now, focus on the spk mounting area, door frame big size flex part and some soft metal part, we added some extra forced on it, which change the resonance frequency of the whole metal frame


Get ready to install the speaker, before install the speaker, make sure waterproof shield had been done properly. Dun waste the money to buy new speaker just because of some small mistake.


Install spk now, the spk should be mount on a solid spacer but not directly on the metal frame. This baffle is to create enough pressure to press on the metal frame and spk and make them solid like 1 piece. a very important note to achieve good sound. In this case, rubber baffle used to enforce the dampening effect in order to reduce the vibration when the spk operating.


ESTIMA Floor deadening and sound + heat proof in extreme level

Car floor pan and mud guard is the noisiest part for road noise, tire noise and chassis vibration noise. To reduce these noise, we use oem material which provide the best dampening effect that looks original and cost effective.

This is the oem dampening material, the material was spray with body color to make it looks more neat and clean.


Now, we apply another layer on top of the current oem layer and any other parts which are not covered by oem dampening


This is the pic after the first piece had been done, looks original rite? except the color which are not important


In this extreme level deadening, reinforcement had been added to provide a stronger dampening effect by changing the whole floor resonance to multi-frequency type. (if only apply 1 layer on whole floor pan, the whole floor pan will having the same resonance frequency which create a peak in the noise coming thru the floor pan. It is not a good idea because it make your whole car become a big hall with lots of echo with that peak frequency)


the whole rear floor pan with the deadening applied

now comes the sound insulation part, by this material, anything around 2-3.5kHz will be block by a maximum of 18dB. (2-3.5kHz is the noise from your tires, engine, exhaust, wind, other motor vehicles and etc) As for heat insulation, this material can block the heat generated by the exhaust from transfer into cabin.


For roof, oem style dampening material wont work, they only work on floor pan.
We use some extra holding dampening material for roof to prevent it from melted and falling off


Because roof usually is a big piece of metal with less structure/bone, some reinforcement should be done to create a better dampening result. Look the the double layer area, that's the reinforcement.


After the dampening, we apply the same sound and heat insulation layer to prevent the noise coming thru the big piece of metal which can be easily transfer external noise and heat into cabin.

Add in a new produce called "Eseal", this product are made from very high quality rubber and it's even better quality than your oem rubber. see youtube video below for this product and some sample...

Installing Eseal will make your door slightly tight to close on the first few days, but this is minimal not like the cheapo version which will make your door hard to close before you sell the car away


install of Eseal

a better pic on how dampening and spk baffle installed


a tweeter pod can hold the tweeter nice and firm...it reduce the chances of tweeter movement while using normal blue tack, resulted in more accurate focus and better staging and imaging

nice description howie

just to add to comment, all 'holes' at the door should be covered. either u can use plexiglass or add another layer of sound dampening to cover up the hole. this is to ensure that midbass is 'seal'. Must also treat vios plastic door panel as they vibrate and induces alot of noise.

will the car be heavier after installing this material?

Nice info!
Thanks!

Where to get the raw materials?

definitely but rewarded with a more quiet car while driving.

pm howie lor... hahaha... or there are ppl who are selling sp materials here @ garage sales

entry level first ma...
for extreme level, aluminium are suggested to be added by custom it to the shape of the metal frame. as for pic, sorry dun have now since my hdd died....
and yes, door panel is a problem for old vios.....too much joining parts.

Added on August 30, 2010, 12:46 pmi believe the luxury are more than enough to cover the loss on other side if 1 is looking for pleasant drive.

as i always dealing with different ppl's car, there's always ppl carrying unnecessary item inside their car. those item might be a few bottle of unidentifiable liquid, some books/magazine, some car spare parts and etc..those item added weight to the car...might as well get rid of them and install these to make the drive more enjoyable??

but, how much weight are we talking about here...<5 kg?

Go find howie, ask him how many pieces required then try to carry all at 1 time.
If you're a boy racer then this is not for you. (howie has other stuff for racer's). If you never drive >110kmh then you wont even feel the weight.

Great photo description Howie. Should get this one pinned for ref.

STP is a very good product but very expensive not suited for budget ppl like me.

One must always know the basic of soundproofing and sound dampening. Diff materials are use for different place and for different purpose. So if any of u guys just slap 10 layers of any butyl-based soundproof aint gonna make ur car quiet. U need ccf and mlv to do that job

but seriously if u compare the effect vs some other brand, it's worth it..only when money is available la..

howie,
for the dampening, did u dismantling the door or insert material into the hole with your hand or with special devices ? .. the hole is quite 'small' for adult or bigger hand ...

sweet tutorial. I like it

use " flexible stick"

the extendable kind?

This one sounds cool, i'm wary about removing panels and putting back together again. Cause my car have pretty hard suspecnsion, worry about it developing creaks and what not. Anyway, how much for this product on a 2 seater? Will it help reduce exhaust sound as well?

my special tool la..lolz..:>

Added on October 12, 2010, 4:41 pm then leave to the pro to do the job....:>
yes it reduce every noise from 40hz-30khz..below 40hz can only reduce a little bit due to car body resonant. If your exhaust is not those very deep and bassy type, then it will work wonder...

howie u do sound proof also?how much does u charge for four doors like the vios there

i do anything to make your car perform better :>

i like tis sentence,should make it ur shop slogan.

Wow!! I like the speaker baffle, izit aluminium..?

lolz, will consider it, but it's too long

This post has been edited by howiechoo: Oct 13 2010, 04:02 PM

it will be fully apply for the door inner n on the metal right??

u mean deadening? yes, this will give best result

actually,wats the different for deadening n soundproofing?

deadening is to stop your car from rattling or panel vibrations.
soundproofing is to block noise (engine/road noise from entering your cabin).

more or less.

my exhaust beat my sound system sounds! using this method can solve it?

deadening is the prevention steps....which you prevent the generation of noise...

soundproofing is the curing steps..which you blocking noise...

vaccine and medicine.

udin901, if u wan quieter ride, why not change the exhaust first? there's no point to generate noise then block noise....waste gas

pm me for sound proof for my lavina 2 door only 2 layer

Bro, today i DIY dampening on my BLM front door, use 4 hours only for 1 door tmr have to continue on another one.

Until this stage, my car adi done deadening and soundproof for floor, front and rear wheel arch (inside the cabin), fender and mudguard, now is door, after that is rear boot (DIY as well)

The material used are STP Vibroplast M1.

I want to play SQ, so i plan to apply 3 layers soundproof.

I have few questions, hope u can help me.

1. Today i only bought 2 boxes (8 sheets/box), only 1 door adi used 1 box, no waste at all, but not enuf for me to cover up the door frame 'hole' (the 3 big hole), is it necessary to cover the hole using dampening sheet? can use others alternative?

2. The plastic door trim is it need to apply the dampening sheet as well? (i thought is enuf, but end up wif no)

3. STP splen suitable to apply on the outer door frame (outside towards the car) or not?

Thank you.

3. Would suggest you to dampen with M1 first then only apply the splen. At least you dampen the vibration then only do sound insulation.

Hey Bro Howie, Where's ur exact location.. Nearby ? Any Landmark..

I don have any pic to show you, just observe by urself, they are few nuts embedded in the plastic clip, just open the screw then u can open the clip, after that just pull out the fender, as easy as that.

---

Added on October 25, 2010, 9:47 pmSure, i adi deadening all the metal frame by using M1. My concern is for SQ setup, is it suitable to apply splen inside the door? i got the answer is no, so how u guys think?

This post has been edited by coolkwc: Oct 25 2010, 09:47 PM

Actually SQ has anything to do with how you soundproof your car meh?

If you already dampen then no need already, or you can add splen on the door that do not have speakers running.

Since you have access to STP, why not apply STP Crystal?

Actually what you want to do? Take out the whole fender ah?

The answer is DEFINITELY.

Like example the insulflex soundproof is a killer to SQ setup.

Yes, agree if you bring in insulflex.

But as long as you don't apply behind the speakers, then I guess it is still ok.

for 1, u can get stp alum to cover the door frame "holes". it treat as a layer of additional frame to your door. for pricing pls pm me. guarantee satisfy.

for 2, yes if you got the budget, but deadening can only reduce the vibration by 50% at most. i got better solution which cost almost same but higher damping effect.

for 3, splen are good to use on floor, side panel and roof. Do not use inside door panel with speaker installed.

hope these help

how much for splen? how big is it?

Guys, since insulflex not suitable for door...how about roof and floor?

it suitable for places where u wan to block heat

Ok..look it more for engine bay....

Then i wonder why seller said insulflex for sound dampening at garage sales thread....

Misleading. i regret putting insuflex on door trim too. Doesnt reduce outside noise also. Prob reduce the vibration from front speakers on my plastic door trim.

Bro, is not "Sound Dampening" but "Sound Deadning"... can install at floor, roof, boot & bonet coz the lowers cost compared to others product like Dynamat, Sika, Brown Bread & etc. Definitely not suitable for Door use.

Actually the low cost is using tyre tube or rubber hose (like fuel hose, small2 one) to eliminate vibration & rattling problem.

My mistake.....wrong in term dampening and deadning....

Hi guys, sorry side tracked a little.. anyone has any idea where to buy bitumen paint in JB?

how much is enough for 2 rear and 2 front wheel arcs??

thkx!

can someone quote me altis floor n roof price? wan cheaper solution other than stp.

just open a new thread for stP product...

:>

price are nego as always

http://forum.lowyat.net/index.php?act=ST&f...0#entry40658836

nice info howie

please keep update this thread

you got message howie

u wan buy CD or buy Splen?

hi, how much to do a Inspira floor for 2 layer that you shown at page 1 ( block 2 types of freq) PM pls

thanks tan for purchasing stp diy kit from me...hope the above picture will inspire ur install.

so insulflex is more to blocking heat rather than reducing road/tyre noise?
so insulflex is more to the bonet and roof I suppose?

bro u sell dose tweeter pod?

dose tweeter pod is?

brief read through. efficient info was given. this very help but yet my hand technique won't be able to produce this kind of result.

bro,if want to wipe off the anti rust grease,u use spirit?spirit=methanol?

u can buy spirit in h/w shop........i think it's not methanol based

shared something today, click below to know more i believe this will make you understand why most people just use bell or gong to test their product.

Car soundproofing tricks and know how

need facebook login la brader

Or they like to knock on your car door..if it sound hollow..they say..SP no good!!!

knock on door will do if he know how to knock and how to listen....

Nice article Howie. Thanks for sharing.

i wanna ask, the soundproof need to really apply alot pressure? cos i put the stp i press the side will come out abit then i press the side on to stick at the metal, is it correct?

Applying pressure is just to remove the air bubbles trapped when you stick the materials on. And of course also to make sure that the material is sticking properly on the surface.

The more detail you can go, the better contact you can get.

interesting topic u got here

just wanna ask, for new myvi, what are the recommended proofing/deadening/dampening treatments using stp product?

i am travelling seremban kl seremban every weekday so my dream is to have lower noise level inside the cabin when cruising beyond 70 to km/h as i notice the noise level still acceptable below 70.

since stp is premium product, perhaps the treatment can be done in stages, right?

perhaps u could pm me to illustrate the commercial figures

Eseal how much.. From the video, seem to be a very good item.

yes, it's a good stuff...u get more lower exterior noise from mid to high frequency. to pair this with door dampening will make it even more better.
