Thread: Sound Deadening

Calm people...

Or as the cool kids are saying these days, "Keep Calm and Rover On".

Hmpf, I thought it was "chill-ax" that the cool folks said. Oh well I have never been cool anyway.... Maybe some foil backed bitumen.....

Here are a coupla shots my thermo acoustic install progress

I have insulated the seat boxes inside and out, the floor and door skins and also the inside of the roof. Also under the second row mat and the cargo area mat, all made a difference not just in noise but also heat.

I used 10mm acoustic foam with adhesive backing and foil on top.
Then covered it with 'mass loaded vinyl', very effective.
Also covered all the joins with adhesive foil flashing.

This has made the aircon actually seem quite adequate which was certainly not the case before all the effort.

However the singe biggest impact on noise reduction was this

Probably another 50% reduction on top of all the other insulating efforts.
Driving with the vents open which is something I usually avoid simply because of the engine noise that comes in with them open is totally different.
virtually no noise at all !!!
The best money I have spent on the comfort factor by far.

I will download the noise measuring app and post results although i wont have a before result.

And a comment on heat reduction.
If you have a cat this is another good reason to get rid it, they act like a radiator on the passenger side giving off a lot of heat.
Get a roll of that fiberglass exhaust bandage and run it from as close to the manifold as you can all the way to the main muffler (if you still have one) this dramatically reduces the amount of radiated heat from the exhaust coming through the floor.
Get a roll that light blue 10mm foam they use for camping it's in BCF for about $10
When doing the inside of the cabin remove the transmission cover (it is a pain to get off) and cut a sheet of the foam with holes for the gearbox top etc. and poke it down around the gearbox and front of the T/case, I managed to get 2 layers in. this also made a big difference to the amount of heat being transferred into the cabin.

Cheers,
Paul

Hmm that looks interesting - did it impact your engine running temperatures much?
