Soundproofing - Any Suggestions?

[JohnMorr]

Is the Octy 2 diesel (2.0 Tdi) as well soundproofed as possible, or are there firms out there who can make a real difference? I'd willingly spend a few hundred (hush rather than rush) for a tranquil decade to come...

[YeeHaa2.0TDI]

You always do more; use damping sheets (available from bodyshop suppliers or large factors) to stick to any flat sheet of metal e.g. floor panels, boot floor. Use expander foam in any nooks and crannies, pillars and sills(avoiding seat belt units etc).
Then use soundproofing wadding cut to shape under the vehicle carpet; especially under the front carpets, and under the boot carpet and rear seats.

Noisekiller UK (below) produces soundproofing kits for cars, including Skoda. It might be worth contacting them to see what they offer for the Octavia II.

Thanks - I've got onto them already and will be interested in their response. Only disturbing factor is that they also sell one of those woo-woo magnet things for your fuel line - sheer nonsence, IMHO.

Agreed - about as much use as magnetic bracelets for arthritis [bet that starts an argument! ]

But about sound - mine is very quiet, is that because it is petrol???

[WW_VRS]

The petrol is more quiet than the PD engine for sure, mainly to do with blasting in fuel at VERY high pressure etc.

I used soundkiller too, got him to fit it for me in the carpark at work in Bracknell

The main effect is to muffle the sound, and it does have a good impact IMHO. The second bit of sound proofing I did was the PDxxx cover from seat, dunno if that's suitable for your car as well, it fitted the Fabia vRS though.

Other things that may contribute to more noise are the tyres - the lower the profile the more noisy they appear to be for roadnoise, which then gets passed into the cabin.

Thanks all - I'm now in contact with Soundkiller who say:

"We do a octavia kit £165 inc vat. Factory fitting (Manchester) £90 inc vat
Mobile fitting £130 inc vat"

The testimonials on their site are good, though they do seem mainly to be from Land Rover or motorhome owners, who would certainly benefit more from soundproofing than an Octy! But I still think I'll go for it...

WW VRS - what, pray is a PDxxx cover?

[WW_VRS]

It is a couple of bits of moulded foam with a few metal bits in to allow the bits of foam to stay together & rotate. The moulded foam goes underneath the plastic engine cover, over the top of the engine. It fits on the PD100 and PD130 engines for sure. I'd be surprised if it was suitable to petrol engines.

The effect of it is to dampen the worst clatter noises at their source (the injectors).

Sounds interesting

On the Octavia, the TDi under bonnet sound proofing fits directly to the underside of the bonnet. This means it will fit straight onto a pterol model.

[WW_VRS]

Just to clarify - the Furby already has soundproofing under the bonnet - soundkiller adds another bunch of the stuff there too. The PD1xx is extra and goes under the plastic engine cover. As for pics - I haven't got any handy at the moment

Might be worth checking out the following Briskoda threads though:

this one
some more info including the part number and price at the time (original thread)

Then on SeatCupra.net there are some pics, that shows it

They did my Impreza Wagon a few years ago after I had got fed up with the drone from the fully decated Exhaust & did a brilliant job, If its any help I would recomend steve 101%

[WW_VRS]

Standard Fabia vRS myself and I felt it was worth it, the reduction in noise is subtle in some ways but very much noticable & I totally agree with Stuart - Steve's a nice guy and he did an excellent job on my car too

[slider]

Just make sure you don't get an Octy on Bridgestone tyres!!!!!!!!

I find my car pretty silent apart from the tyre noise, I believe those on Michelens are much quieter.

[Tom_vRS]

I have been in touch with Steve, and feel slightly guilty for wasting his time

Whilst I'm sure the kit is not only effective, but also reasonably priced - I decided to do some research and have a no-compromise job done myself. I want to eliminate as much noise as possible, but also deaden where possible to - all ready for a top sound quality stereo install.

I have a bulk pack of Brown bread which is the deadening - it will absorb any panel vibrations caused by speakers etc. I will also purchase 2 rolls of SAPT220 which is a sound proofing material used in machinery. Its not cheap, and is bloody heavy, but will sure do a good job of reducing cabin noise. Its highly recommended on car audio forums.

I might do another thorough coating of laminate flooring underlay on my front doors. Pikey mod #2647

Make sure it's wholemeal Brown Bread, Tom! Can you point us towards suppliers?

Some of them look like Dildo's!!
You can get a mixed test pack for a tenner. Hmmm, Value.....

[JohnMorr]

Earplugs for soundproofing, eh? Not such a silly idea....

I seem to remember a US Hi-Fi magazine (?Stereophile?) which had a column on in-car audio. Someone recommended a powerful system combined with earplugs. The earplugs cut out the car noise, and you simply turned up the audio to the required perceived level!

But pretty awful for the car next to you in a traffic jam.

Has anyone done their doors? Mine just don't seem to cope with the Audience system
