Sound proofing

I have had my 130 dual cab Defender for over a year now and after an initial burst of throwing money at it I felt that the 3mm sticky backed alloy foil didn't really improve the noise reduction that much. Me, I'm nearly fifty with the normal hearing loss, I don't mind it, my Lady not so. So its phase 2. Strip out all seats, mats and give it a clean. Then after a lot of looking at other peoples idea's and trials I have decided to leave the sticky foil on and place rubber backed carpet tiles over everything I could, carpet side down. Another important point to note is the filling in of any holes or gaps and believe me there are lots on a hoover, sealastic, plates they are my tools of choice.

The reason for this is to absorb noise and vibration, just my thoughts I could well be wrong time will tell. Focus area's being the rear of the cab, lots of road noise being reflected through there, the gearbox tunnel, the cover is rubbish as far as noise reduction goes and the seat and cubby area's, another high noise transmission area.

I have missed all the rear of the car photo's but you can get the idea. So far this has cost me around $200 and I will take it for a drive next break to see/hear the results. The only area of concern will be the carpet face down in the foot well area's getting wet but the next fix it job is the leaking air con, should be a straight forward fix. Will keep this post updated as I go.

For me the most annoying noise complaint is wind noise on my 2012 110 wagon. I think it's just about impossible to stop it, i have heavily insulated my roof with dynamat and eva foam, with minimal results. Unless someone comes up with a great way to seal between the windows and door frames, and door frames to body. The engine noise is actually bearable from the 2.2.

Noise-cancelling headphones? :)

Our County is a V8. Don't mind the sound so much :D

I actually thought about that, well the technology anyway.

:cool:

I just fitted the Dynamat from the front of the seat boxes back in my 90 and we noticed a big difference, the plan now is to do the firewall and foot wells next

I have used a dynamat type product (Stinger Roadkill) all through the back of my 90 and the entire roof. Also in the roof I used Formshield 10mm. It made a huge difference and I now don't hear the wind noise from my Hannibal roof rack.

I had the whole dash out a few weeks ago chasing a rattle which turned out to be the wiper mechanism (worm drive) rattling inside the metal tube (rack). I stripped the whole lot down and gave it a good greasing and reinstalled. I then used a closed cell foam pipe lagging and cable tied it to the outside of the wiper rack. Now I just barely hear the wiper mechanism when stationary, when driving I don't hear it at all. Well worth the weekends work to have quiet :D

While everything was out, as to get the dash out you need to remove the plastic transmission tunnel and the rubber matting. while it was all out I put some Stinger on either side of the forward part (metal) of the transmission tunnel, just this alone has made another huge difference to the sound coming up from that area.

So all in all I have had a very positive result from using soundproofing in my little deefa.

Hi I used dyna mat on my 110. Made a difference. I also applied a noise/rust product to the wheel arches. Now a stone flicks up the passengers don't have a heart attack.
If only I could find a quiter windscreen wiper motor.

Tony, read my post above ;) it was worth the effort. The noise will be coming from the rack more so than the motor.

Thanks Cracka
I will have a look. I have had a few 110 ,s and very one has had a very noisy wiper motor. I don't think anything is wrong it is just loud. But the lagging sounds the way to go.
Cheers

Bushman83 has a video on this:

Down in the comments, he says that he added 12mm closed cell foam to the roof lining and some other areas a bit later on and that doing so was a significant improvement over dynamat alone.
