Hello again,

I am looking to soundproof my SIII when I have finished my rebuild and was going to use SA25 and SA12 from: Prices for soundproofing materials.

I was looking for advice on where to put it i.e. in the bulkhead etc.

And I was wondering what you have covered yours in when put in the cab to make the cab look nice and finished.

Yours,

Matt.

PS. I have looked at the soundproofing links :)
 
Has anyone actually attempted to soundproof their series landy and noticed it has made much difference?

I would personally never clad the inside of my Land Rover in foam...to me that is a recipe for rust.
 
There was a guy at Driffield selling sound proofing foam - it was very cheap and i was tempted, but, was dubious to its real affect... So I guess I am echoing Rusty's question... :)
 
I don't have any sound proofing fitted at the moment, but when I had a Transit engine in my SIII it was a must. I used some old carpet and underlay which made a big difference to the noise levels, but looked ****, soaked up water, went rotten and made the Landy stink. I find the 200Tdi engine is just about bearable with no sound insulation. I personally would not bother sound insulating a petrol series. Making a tidy DIY job of fitting foam around the transmission tunnel is going to be a tough one.
 
I bought some shaped mats which are very thick, seems to stop some of the vibration through the feet and have the benefit of making it seem physchologically quieter.
 
In my series 2A, I have used dynamat in the doors with plans to use it in a few other places like on the roof and fire wall as time goes on, it is great for reducing the noise and in theory good for keeping the warmth in. I also plan to get the stuff they stock to put under the bonnet.

I also have the moulded matting from exmoor trim for the front and the big heavy mats they supply for the rear which sit on a linoleum floor - so i guess that make two layers of insulation back there. The moulded matting alone made a huge improvement. The downside as everyone will agree is it is expensive, and a little time consuming to install - perhaps though less time than making a custom fit.

The result if measured might only be a 5dB reduction, but to my ear the result seems great. Another positive is it looks good, I have had many positive comments about it.

Lastly I think the condition and use of your vehicle needs to play a large part in your decision making. For me 90% on road the rest off road. The noise that made my ears ring was the long on road trips at speed, not the slower off-roading, If all I did was off road I'm certain I would not have bothered. If it was rusted and corroded I would have also been less likely to stick expensive dynamat to parts which are liable to fall apart or need replacing. Another consideration is if your are constantly getting your vehicle wet the moisture will be slow to escape or dry under the thick exmoor matting so this could make a rusty even worse I guess. Good luck with what ever you decide


Cheers
Jonathan
