I used an app on my cell phone today called NIOSH. it measures sound but isn't calibrated so your results may vary. The phone is mounted on my 67 designs phone holder that's hung on the Archetype Racing BYOD rail. It's just to the right of the steering wheel and level with the dash. Sitting at the light the ambient sound was around 44 to 45 decibels.
Driving at 60 mph the sound was in the 65 dB range
And then on the 5 in a section that's got grooved concrete with a fairly windy day and doing 75 mph it was 75 dB.
I have stock Good Year Territory "Wrangler" 315's on the truck and the driveline is stock. The section of road I metered was pretty much about the loudest section we have around.
And I can't show any before because I honestly didn't think to do it before. Actually I was just too impatient to wait to do it once I had the time to get into it.
Our 2D Badlands Sasq still has the factory tires and no sound deadening, I'll get a db reading this afternoon.This is perfect! Just need someone that has a similar setup without the sound deadening to do the same lol. If not I can do it when I get mine in a couple months
Some people use "peel and stick" roofing as a sound deadener as a cheaper solution than Killmat. You may want to visit a roofing supply store. They make that stuff with a white outer layer to reflect sunlight.That's an awesome job you did. I have a plan to paint my MIC white even on the inside and wonder if there is a product that can either take white or is white out of the box
there are acoustic hex panels in white and sound dampening paint -
any opinions or experience with whether they are effective in auto applications?
Trying to lighten up the cabin with a white interior roof and the sound deadener from the factory seems to look like grey carpet
Be aware that the roofing material will give a smell of asphalt for a while when it gets hot in the summer. Eventually it will wear away or you get used to it.Some people use "peel and stick" roofing as a sound deadener as a cheaper solution than Killmat. You may want to visit a roofing supply store.

I used FatMat on my Raptor. I’m sure similar to Kilmat. Great project. No smell.The Kilmat does have a top aluminum layer that is essentially supposed to be a thermal barrier. Roofing material I would guess is likely more fragrant than I could handle personally. But I haven't really tried and honestly if the price of one package of Kilmat is too much for the budget than I kind of question how the Bronco could be afforded?
