Sound deadening the headliner worth it?

I have a bunch of noico sound deadening material left over from another project and was thinking about doing under my headliner to cut down some wind noise from my prisu rack. Has anyone done this and is it worth the hassle? Just debating if it is worth the time to tear it all down and do it or if I will barely notice a difference?

 

That kind of noise would be better to use a mass loaded vinyl. Look up a cheap mass loaded vinyl on Amazon and get some 3M heavy duty mounting tape to mount it with. I literally just did my entire cab with noico and the mass loaded vinyl. Makes a world of difference

Edit: there’s 3 types of sound insulation. Dynamat material, mass loaded vinyl, and closed cell foam. Dynamat is good for noise that travels through the structure like road vibrations/bumps. Mass loaded vinyl is good for airborne noises like your exhaust, wind, outside traffic, etc. Closed cell foam is good for stopping panels that like to vibrate and make noise from vibrating and making noise

 

Are you talking about the noise from an empty rack, or do you want to reduce the noise from when you are hauling something up there?

You might notice a difference on an empty rack, but with gear up there, it seems like there is so much wind moving around the loaded rack, you get noise coming in the windshield / windows.

 

Agree with Anchovy. The deadening material alone won't satisfy your desire for noise reduction. Definitely need to use MLV or at least some acoustic foam or combination of all 3 materials.

 

I will look into the vinyl. I used to install stereos for work a good 20 years ago and am very familiar with the dynamat style but have never used the vinyl.

 

It’s not that bad to work actually, I used that 3M tape I said to mount mine on my doors, floor, and back wall. Can’t be too stingy with the tape though

 

interested bystander: Q - how much of a pain to remove the headliner without discharging the side air bags ?

 

It's a bit of work to remove, but the airbags aren't a concern. The A B and C pillars need to come off, so you start at the door sill panels and work up the B and C pillars. The A pillars are easy. Gotta unbolt upper console, dome light, grab handles, and most importantly, the rearview mirror. Trust me on the mirror... it gets in the way and your headliner will rip it off and shatter your windshield. Don't ask me how I know this

 

Pics or it didn’t happen

 

you know . . . . it's really not that noisy after all . . .
