Sound Deadening Experience

[Cclittle72]

I did my doors a couple of months ago using a combination of Dynamat Extreme and Second Skin. They were pretty easy. About 30 minutes or so each, you can do them one a day as you have time. They sound a lot better now when closing. No super noticeable difference for road noise.

Then I did the headliner. It took me awhile to work up to that one, but I found a good video (below) and finally found some time. For both parts, I covered as much of the exterior metal as I could, between the beams.

The next bit describes my experience with the roof...

I dropped it down about 8-12 inches and left it in place in the cab. I cleaned the metal with Simply Green, then wiped with rubbing alcohol. Mind the clips when removing the pillar material - there are metal bits that can come off and fall into your frame. I think I lost three that way. I never replaced them - everything still stayed in place, and the fallen bits aren't making any noise.

Time needed: about 2-2.5 hours
Results: Noticeable (70%?) drop in wind noise on the top of the truck... up to about 70-75 MPH (depending on wind speed and direction). Above 75 it gets worse, and it's still pretty bad about 85. What it does do is make you more aware of the wind noise still coming from the door windows and rear of the cab areas.
Advice: for those with light colored headliners, be sure to keep your hands clean before touching the visible parts of the liner! It also takes good shoulder stamina to roll that much stuff on the roof.

I'm hitting the rear of the cab in the spring. I also picked up some foam-backed MLV that I'm going to put over the rear floor when I do the rear wall (will take the rear seat out for all that).

No pics, sorry!

Stuff I used:

[Ranger Lariat]

Did my doors the week after I bought my
LARIAT / TREMOR (Dynamat). As I was at the dealer and looking at the Ranger, and as it would turn out the truck I would end up buying, I knocked my knuckles on the door in front of the salesman and shook my head. I said, “well that will be the FIRST thing I “fix””!

At least now it sounds solid, even if it really isn’t?

I considered doing the roof, but the plastic clips that hold vehicles together these days…. Well the door skins are bad enough.

Oh, placed 12” square acoustic foam pieces inside the doors behind the speakers too.

I've watched a few videos on soundproofing and what I found is that you can dampen the vibration of panels by attaching the sheets. To insulate outside noise a foam cell sheet will quiet the interior more. I haven't quite figured out how to choose thicknesses.

Pulling back the carpet seems to show the back doesn't have the amount asphalt sheets as the front and I don't recall there being any under the seat storage.

Crawling under the truck appears that the factory damping material below the rear isn't as present as the front.
