HowTo: Sound deadening (Doors) Bulletproof+Inexpensive

[TStar]

that's a "small" tutorial how to dampen the inner+outer plates and the the door trim of your Mazda BJ .... (rockon)

nice how-to. i wish other how-to's were put into pdf form.

great how-to, but the paste/paint on deadeners don't work nearly as well as mat deadeners. i've use 4 different paint/spray on deadeners, and they all suck compared to even the cheapest of dynamat alternatives (peel-n-seal from home depot). if sound deadening is your goal, sheet metal insulation (dynamat or alternative) plus acoustical insulation works best. i prefer raammat60 bxt and ensolite for serious sound deadening.

What the hell is the foam piece for anyway?

well i thought about the material a lot... i read forum threads (elsewhere) that the pastes are good,maybe even better than the sheets... i can't really say anything yet (speaker not yet plugged in) but since some people made good experiences with the pastes, it's alright with me...(at least they got 1 advantage for sure: they're not heavy at all and the door will always shut correctly)

What the hell is the foam piece for anyway?

you mean those styrofoam blocks and the black part in the rain foil?
the EPC says it's a pad/cushion, so it will just stabilise the rain foil in the large hole...

seems like alot of work for something that dynamat or brown bread can do.

both ways are alot of work ---

pastes/paint on deadeners are only good for areas that you cannot easily reach with mat.

if your only goal is sound deadening, then ensolite insulation is what you need. it's light weight and 1/8" thick. the pastes are just a variation of sheet metal insulation, which is primarily for keeping the panel from vibrating. but the best way to keep a panel from vibrating is to mass load it, which is why mat based deadeners work better than paste.

and my doors close fine with the 40 sq ft of mat on each door.

thanks

i've used regular carpet padding, jute carpet padding, and ensolite. the ensolite doesn't make your carpet bulge, which is a plus. this is the stuff i prefer if i don't use ensolite:

i haven't tried this stuff yet, but it looks interesting:

the ensolite you'd be able to put down 4 layers to equal one layer of carpet padding, so if money is not a factor, then it is definitely superior.

my car is all ready fully dynamated -- but at the time it was done -- i was not educated enough to know that it would not help the road noise as well as the pads --- it works perfect for loading the metal and keep it from vibrating -- but im thinking of putting padding over the dynamat to try and reduce road noise a little more ---

that Jute seems inexpensive --- but the ensolite is thinner --- how much and where can i find it to compare -- thanks for your time

 

[ghettobubba2001]

lol that would take waaaay too long- dynamat <3

the ensolite is wider, so you get more per linear yard than with the jute. i used contact cement to apply it, but it was kind of hard to work with. if i had to do it again, i'd probably use spray adheasive.

 

[bonesmp5]

it took long time -- and edges of the mat are sharp -- looked like there was alot of paper cuts -- lol -- good thing I didnt do it myself - hehehe

[bonesmp5]

thanks alot -- that doesnt seem to bad -- now i just need to figure out how much i need and where i want to put it -- Im thinking mainly the back flooring and over the wheel wells -- still not sure if its worth doing the inside plastic door panels ---

thanks again for your time -- Billy
