Recommend me some sound deadening

[ripped_fear]

As above. I'm looking for some reasonably priced sound deadening to do the doors of my supra.

I plan on doing most the car, but within the next month I'm going to be doing some audio and work on my door cards so thought I may aswell do the sound proofing at the same time.

I'm looking for some that isn't too heavy but should do the job, any recommendations?

Thanks in advance

Jake

I did my entire Monaro with some of the eBay stuff. The car smelt like petrol inside for months after. Did the job and eventually the smell went away, just be wary of any odour when you buy some as it's not nice.

I've previously used a brand called e-dead. Seemed pretty good.

Oh God really! I'm not having that! Thanks for the heads up

Thanks for the recommendation, did you have a odour problem with that one?

Should expect such a reply for your good self. However this is not due to exhaust noise this for squeaks in the doors and speakers.

I've just done my doors with silent coat then 9mm ccf dodo mat, doing the rest of the car with that. Already working very well.

Take a look at Zachs (Hemanhead) thread: http://www.mkivsupra.net/vbb/showthread.php?329684-Project-800&p=4137590&viewfull=1#post4137590

 

He went to town and did a very good job. He used Dynamat Superlite.

[el_bandido]

Further info - I used the 2mm silent coat. Incredibly easy to work with and easy to cut. Was quite cheap as well, a 4m^2 bulk pack was about 85 quid. The equivalent area of dodo mat 9mm closed cell foam was another 40 odd on top, but that's a big chunk of the interior. The CCF is incredibly light and very effective acoustic and thermal insulation.

 

I think I'm going to have to get some 3mm ccf for the transmission tunnel, as 9mm is too thick to get the carpet to sit back on correctly.

 

I ruled Dynamat out simply because it was incredibly expensive and didn't seem any more effective than the silent coat.

Cheers for reminding me of that link, He did a fantastic job. I intend to do the majority of the car but will be done in stages as and when fitting new interior trims. So I can work through it methodically. I will price up that stuff.

Thanks for the info,would the silent coat alone be up to the job or is the additional dodo mat needed to? Do you have a link to where you ordered yours? Also did you experience the smell stated above?

However this is not due to exhaust noise this for squeaks in the doors and speakers.

 

Why do you need soundproofing for this? Surely fixing the squeak is going to be easier, my doors and speakers don't squeak and I've ripped half the sound deadening out of my car.

Silent coat/Dynamat isn't acoustic insulation as such, it's designed to add mass to alter the resonant frequency of the panel it's attached to. It will reduce road noise, but adding closed cell foam where you can will make a big difference inside the cabin as well. The weight of the CCF is negligible. I imagine you will see a marked improvement with only silent coat/Dynamat, but if you're doing it all anyway, you might as well add some closed cell foam where there is space.

 

Didn't notice any smell whatsoever either while installing the silent coat, or while sitting in the car afterwards.

Sorry I may not have been clear. I'm not looking at this as a solution to the problem I know it's ny speaker brackets rattling atm, but as I'm doing a retrim I want to make sure everything is done to a high standard so it seems a no brainer to do this while I'm there to stop any unwanted sounds in the interior. It would be nice to get shot of a bit of road noise to.

Ah OK thanks you seem much more clued up on this than myself. If doing the job it sounds like it would make sense to do both. Where did you order yours from? And what sort of quantity would you recommend.

Ah I see, yes might as well then. Interested to see your review on it.

IIRC silent coat is made by Car Audio Direct, here is a link to their products - http://www.caraudiodirect.co.uk/catalogsearch/result/?cat=&q=silent+coat

 

It's amazing stuff to work with, make sure it's warm when putting its on (use a a heat gun if necessary) get a roller, sharp knife and some gloves because it will cut your hands to bits!

Spot on and sound advice

 

Jake, please do some reading before spending a load of money on products and falling into the trap of putting a dynamat type product all over your panels - it is simply not needed.

 

What you have to think of is that there are different types of sound that you need to work against and for that reason you need different products. In the most basic form - some Sound Dampener (e.g. dynamat) and some Sound Blocker (e.g. a closed cell foam product such as Silent Coat).

 

Put simply, a metal panel is subject to vibrations that case soundwaves to resonate through the panel and into the car at low frequencies - all you need to do is apply 'dampener' to about 50% of that panel in the centre and that will be enough weight to stop the vibration. There is no need at all to apply dampener to every inch of every panel. All you'd be doing is adding weight without increasing the sound dampening abilities above and beyond what half of the material could do. Once you've stopped that sort of sound, whatever material you're going to use as a 'blocker' needs to be applied on top; this should cover the whole of the panel in question. I have used these principles to great effect on my own Supra but unfortunately didn't take any pics before the interior went back in

 

For more info have a read of these links:

I got all of my materials from here:

In the most basic form - some Sound Dampener (e.g. dynamat) and some Sound Blocker (e.g. a closed cell foam product such as Silent Coat).

 

 

FYI - it was dodo mat that's the CCF, silent coat is equivalent to dynamat (i.e - adhesive dampener).

 

edit: also want to echo the point that you don't need 100% coverage of everything. About 80% of a panel will be sufficient for silent coat/Dynamat to effectively alter the resonance of the panel. Closed cell foam will benefit from more coverage, but don't stress about squeezing it into every last gap.

I got given some silent coat and it is very easy to work with.

 

I then just bought generic 6mm CCF off eBay and I am looking to buy some more of the same supplier. The CCF is very stick and i sometimes got it stuck to itself when applying in the doors

[mwilkinson]

Thanks for the recommendation, did you have a odour problem with that one?

 

No problems that I recall. I used both the standard foil backed tar stuff and a high density closed cell foam.

 

Used it in the doors, transmission tunnel and rear quarters.

[ripped_fear]

This has turned out to be massively informative!

 

Thanks so much all for taking the time to go into some depth and have learnt a bit from this morning thats for sure. I will take the time to read steve's link (cheers mate) before I do any ordering.

 

Some good info and feel free to keep it flowing should help others loooking to do the same job too.
