My Octvia Estate does have quite alot of road noise. Ive used Dynamat Extreme in my old Fabia Vrs with good effect but its ridiculousy expensive.

eDead Original (& Eliminator version) seems alot cheaper and appear to be much the same. Plus it looks alot neater beacuse its not covered in logos like the Dynamat stuff.

However I am trying to find out how the two sorts of eDead differ in performance etc and how they campare with Dynamat Extreme.

Can anyone offer any advise?

I was going to use quite alot and do the whole of the boot floor and inner rear wings.

The thing is, this type of sound deadening is great for reducing panel vibrations, e.g. for when you have a subwoofer, but its not really going to reduce road/tyre/exhaust/engine noise very well - its not what its designed for.

I too am looking to improve the sound deadening in the boot of the octavia, but really you need a heavy felt/foam type material that absorbs sound...

Just my thoughts.

Also, I bought a massive roll of BrownBread for under £100 delivered, and its done 2 ICE installs, and I have over half the roll left - this will be used on the door skins to give better bass response from the speakers, and reduce vibrations too.

I've got a few rolls of dynamat extreme in the boot of the hatch and would say that the spare wheel well is probably the most important area to do, followed by the section above the exhaust and then the area under the rear bench.

I was thinking something like this for the boot area

NoiseStop Systems NoiseStop Foam

Noisekiller UK - Car Soundproofing - Vehicle, Industrial, and Marine Sound Proofing

These guys seem to know there stuff. I think WW_VRS had his Fabia done by them .

Noise killer are good.

As for the stuff you linked to above that ,I'm not sure that would be too effective without some mass damping also.

The two-stage floor that you find in the elegance seems to make a big difference. The standard models are quite a bit noisier.

To reduce the noise, just change the tyres

It made a big difference for me
