Adding sound deadening. Soon.

[Area51BS]

From watching Sandy Munro's teardowns, sound control is super interesting. The OEMs do computer simulations to identify thrumming panels and have a whole litany of solutions to throw at it. Sprays. Stick-on material. Stiffening ribs for die-cast parts. Laminations. The trick is solving it with the cheapest, lightest possible solution, and keeping it easy for the assembly line.

I'll be really interested in watching your progress, as I'm guessing Ford hit cost targets by passing up sound proofing where they could. For those monitoring his results, remember that 3 db is a perceived doubling of sound level.

More like 10dB. In car audio, I use that as an example because people can relate to it. Doubling amplifier power only results in 3dB increase in sound level. 3dB is just noticeable for most people.

I'm curious on how easy it is to pull apart the doors. I hope it's not too difficult! I always want to watch a video of someone pulling apart a panel before I do it myself because I feel like I tend to pull in the wrong direction and usually risk breaking plastic clips lol.

Someone posted door panel removal to change speakers.

Watching. Agreed that the truck is quiet to begin with, but I'm driving this thing for 10 plus years, incremental benefits will add up. I plan on doing the same.

I reached out to my local Ziebart and got a quote for adding a sound deadener undercoat to the truck. They told me $149, which seems very reasonable to me to limit road noise and get some added rust protection as well.

Any warranty implications? How much does a coat weigh?

I don't have a direct answer to either of those questions. I can't imagine the weight impact is too high from watching the spray on install video. I may have to ask my salesman when I pick up my Maverick about the warranty. I plan on keeping my truck for 10+ years and I live in Indiana so I plan on adding some rust protection but I may need to wait until the warranty expires if that is the case.

Majority of under back seat now done. Will be driving later to see if it made any difference.

I have done that, but I'm not sure it's legal everywhere.

Good stuff. keep us updated. I also contacted Line-X for undercoating. Since most noise is from road/tires. I'll post my differences as well, would love to compare.

Thanks Area51BS - I was totally wrong that 3 dB is a doubling of perceived intensity. I've had that misconception for decades (I think from an ancient Car & Driver article). I Googled after your comment, and yea - it's 10 dB like you say. And who knew there was a " Noise Abatement Society "?

I've taken a different approach to sound deadening. Joined the Air Force, worked around jet engines for 26 years, now all sounds are deadened!

Be in your area soon. Recommend a great BBQ place?

You might find this interesting. My first car was a 67 beetle. Back in 83. For sound deadening I flooded floor with roofing tar and covered it with tar paper before carpet went down. Next was a new Ford 86 Escort GT. Stuffed all hollow cavities above floor with blown in insulation. Guess you could say I am not a fan of any noise. Nothing done on 5 Ford trucks and one Chevy after those. But like I said, this truck has me excited to customize.

Did the blown-in insulation attract and keep moisture? Even if the cavity was tight to the outside, dew can form there.

Had that car for a long time. Never had rust.
