Hey guys I went through some old threads there was on Sound Deadening, not so much for Audio/Video use as much as blocking out road noise, and most of all exhaust.

After reading a few threads talking about the wannabe "Lexus" style quiet cabin.

I was thinking of putting down a layer of E-Dead

Then some ensolite

then finally finishing with a layer of Jute

If that is the correct order that it all goes in, my question is although the E-Dead is the press on style, the ensolite and Jute seem to need adhesives, would I stick them over the panels of E-Dead I put down? Another forum I saw someone stuck the two layers together and used it like another layer of carpet under his carpet and proclaimed it was the better application , I'm just a little confused by how they are supposed to be applied as I'm a noob to sound deadening and its installation.

Anyway, any help would be appreciated.

 

Recommendation, if this is allowed, second skin audio

 

Have you used their stuff? I see they have a product called spectrum which is supposed to be the road noise destroyer apparently, but would this be better than the original 3 layered idea?

 

I have, and I have gone to other car audio forums and read reviews and opinions. This is basically the cream of the crop sound deadening, and you pay for it. It seems from most of the reviews of edead I have seen, this stuff falls off easy compared to secondskin and even raamat.

They have recommendations on there site for exactly what you want to accomplish.

Basically secondskin is one of the best premium products, and raamat is in the "good value" category

 

Understood, would you recommend going with just the Spectrum product or going through the whole damping mat, then noise barrier, then noise coating, or what steps and products did you use, and how effective has it been? Is it the tomb like silence they tout it as?

 

I didnt want to add all that weight, so I went with spectrum, and it helped, but since I didnt do as much as you want to do, its not silent by any means.........

The biggest thing to do is add layers.. There three step is little weird on there front page (secondskin audio)...


It should be.....

Damplifier/Spectrum
Overkill
then Luxury Liner stuff..

I think there three step was meant to have the spectrum applied to under the car (outside) as the final step, which is possible, but thats a BIG PAIN....

 

Gotcha so if you were to go the route I'm looking out you would put down the damplifier, spray over it with spectrum, then spray glue the overkill on top, then spray glue the luxury liner on top of that? Btw thanks for the help man, really appreciate it.

 

if you have the money, yes I would do that. I might just skip the spectrum step though. But yes, if that doesnt make the car quiet, I dont know what will..

 

Right on, now I just have to try to figure how much I'm going to need to do the interior, appreciate the help man.

 

I’m not sure I understand all the comments in this thread, but going forward with my potential misunderstanding, I would like to offer these comments (which may not be an appropriate response to the contributors on your thread).

Sound-proofing and sound-deadening are very different. In your home, you can create a sound-proof space (using specialized sheetrock, multiple layers, and special taping methods and materials). “Spray-on” products are also effective here.

In your car, the goal is sound-deadening. You cannot “sound-proof” your car since there are too many joints that defeat this effort.

Any “spray-on” attempt to provide sound deadening won’t work by itself in a car. “Spray-on” methods are useful for sealing seams, but always require applying a thick layer of sound deadening material to provide a complete and satisfactory solution. The idea is that you need an absorbent layer, and that is not achieved by spraying a compound material onto a surface you want to “quiet.” A “spray-on” solution would require more layers than is financially and practically reasonable for decent sound deadening in a car.

Certainly a “spray-on” technique is useful for the car’s exterior (the wheel wells are a good example).

I didnt say anything that would disagree with your statements. Not sure if I completely agree with your statements, but I will agree that a mat material is better at sound deadening than the liquid. Thats why I told him he could skip the liquid step to save time and money, unless he wants to do underneath the car of course.

 

Well I don't want it to come across like the car is going to be as quiet as an S65 inside, but I'd like to come as close as I can on the platform. I realize the car is a fairly rough riding sports car with the wheels and diff sitting right behind you instead of off in the distance in the trunk transmitting more noise into the cabin just by how the car is designed. I just want it quieter, especially with the exhaust drone, if I can try to get it as quiet as possible by doing things right the first time, that's the way I want to go.
