Does anyone know the best sound absorbing material?
Rebuilding a 71 Dart and do not want to hear the road noise only the sound of the 500+ hp 440 under the hood.
Also looking for carpet as the old carpet was well old.
Thanks
 
Click on the SEARCH tab above... type in carpet or sound proofing and you will be amazed at the amount of info that is readily available.

Heres an example link:

FYI- I used Peel and Seal from Home Depot/Lowes as heat barrier/sound absorber. Its in the roofing department and a less costly but effective option.

Dynamat or other similar product.
i did floor, trunk and doors with dynamat and improved door and window weatherseal, after that my duster was really quiet.
At 60mph noise was same that my 2005 volvo v50 had, and if road is bad duster is quieter, but i still can hear my 318 roar 8)
 
I used "hush mat" its cheaper than dyna mat by 50%
any local audio shop should carry it..
 
Please don't get dynamat - you're buying a name and spending twice as much on a product that works just as good as other competitors. I have heard good things about hushmat, but can definitely vouch for raamat www.raamaudio.com the guy (Rick, i believe) is supremely straightforward and will take his time to make sure you're getting what you want, not what he wants to sell you. I've used the stuff on three cars now, compared to dynamat and the only difference is in the price tag... That crazy steep dynamat price tag. Hushmat can be found on amazon for a good price, too. I have read on several accounts that the home improvement deadener has a tar based adhesive. If the smell is no issue, then rock away with it on the floors, but I don't think I would use it on vertical surfaces as it may slip down on hot days (again, this is only what I've seen and read, im not sure about specific hi products).

Ah! And raamaudio also sells the ensolite pro. That stuff also really helps with the acoustics in the car and keeps sounds deeper and more rich from your speakers, not to mention it adds some softness to your feet under the carpet ;)

This isn't an ad, I swear lol I just hate to see people splurge a ton on dynamat when it can go towards a bitchin fuel injection setup or something shiny :D
 
I've used the Peel & Seal with good results on a few vehicles. I'm too cheap to pay for a "name brand" if I can get similar results for less $$$. Expensive though they may be, do you honestly think the other stuff is specifically designed for an automotive application or a re-purposed industrial product?

First off, ALL of these products are HEAVY. That's how they work, they reduce the resonant frequency of a sheet metal panel by increasing it's mass. But you don't have to cover the whole panel to get good results.

Peel & Seal has an adhesive layer made of rubberized asphalt not just "tar". I won't claim it is absolutely odorless, but it's not bad. Read glossy brochure here: [ame]http://www.solutions.mfmbp.com/MFM-014%20ps%20brochure.pdf[/ame]

I wouldn't worry too much about heat. If you've even been on a roof or in an attic during the summer you'll understand that pretty much any roofing material has to be pretty darn heat resistant. In fact this stuff did a great job of blocking floor heat in my TR-6. I don't know if I'd put it on the roof panels above my headliner though. I might look for something lighter or spray-on there.
 
Thanks all for the info. Will start looking into them all.
Still have time, before project starts, so it is the right time for research.
 
I used Dynamat and am very happy with the results. I can carry on a conversation inside the car now. I bought it very reasonably from Amazon.com.
 
I did the peel and seal, which I learned about on this site. Previously I've always had hushmat. I will say my interior is still a bit loud, but better than it was, and for $50 for the whole setup, it's not bad.
