Sound deadening

[stevep1590]

How have y’all had success with the sound deadening the inside of your vehicle? Floors, doors, cargo area, wheel, wells, exterior aero upgrades? I may be willing to spend some money on this to alleviate that noise. I drive around a lot of highways. Let me know of your experiences!

I did the cargo area and all four doors with some Amazon on-name sound deadening and it helped a lot (doors have more of a solid sound now). Still getting some road noise from the Goodyear MT's though not as bad. Once they wear out I'll swap them for something a little quieter. BTW, you don't need to cover all the surfaces completely. I just applied it to easily accessible areas.

thank you for this!

Great success.

Resonix deadener on metal and the black absorber on adjacent plastic onner faces works great.

I did sound skins on the floor, doors and cargo area. 10/10 would do again. We’re all still driving a shoebox through the wind but it’s a worthy project.

I did soundskins everywhere but the doors plus armorlite flooring. Totally worth it, it's a quiet ride and it improved how my upgraded audio system sounds. The doors will get done eventually.

I agree with others here. I’ve done extensive work and trial and error. The kilo mat plus closed cell and 3m thinsulate works amazingly well. I have a video I’m editing on how I did mine. Should be done soon. Did lots of Db testing. Doors are big and so is floor. The headliner is not a big bang for buck but does help absorb sounds once’s in cabin to give a more premium feel. Also believe it or not the largest change of frequencies in the cabin was adding Mat to inside of skid plates. I have full skids and I used neoprene washers. Huge change in road sound. The bronco can be nearly as quiet as a nice suv such as an Audi q7. Just takes a few afternoons and $5-800 in materials. But your sound system will be the big win. I thought about upgrading but now it sounds premium and we found we can’t turn it up as loud anymore ha!

The testing charts I attached are probably a little louder than what you should expect. I have icon uca and those things really transmit the road noise and I’m on portals which don’t add noise but push tires well outside the wheel well so that adds substantial turbulence along sides.

Also as other commented. It’s a brick so above 60 mph you lose the battle to aerodynamics.

I did the cargo area and the bottom of the cooler in the rear floor. I also did in the passenger side around the factory sub. Going to be pulling the enclosure back out to do a little bit more since it rattles still and going to be completely doing the back of all the rear plastic panels since they also rattle from bass. Definitely a quieter ride but I also have a louder exhaust that I installed. Planning to do doors soon. I honestly don't know if I'll ever get around to doing the floors. I really don't feel like tearing all the interior out.

Thanks all. I found a shop in Austin that does this work. I got the full Soundskin package with install. $1,660

I never thought of that. Might do it now just to see. Thanks for that insight!

I'm doing that too!

Cool . Let me know what you think. It didn’t change the Db on the test but the sound was definitely lower in pitch to ear. Like “no way” lower sorry that’s not very quantifiable but very real

How about any aero dynamic fixes? Window side rain deflectors, etc..?

what did you use to track the sound dB? I have the dB x app on my phone and it recorded like 75+
