B Quiet Sound Dampening
 

Hey all,

Searched around a bit but couldn't find any info on people using B Quiet sound dampening in their audio builds. Im planning on doing 60-70% of the car to help keep the road noise down as I intend to do a few road trips with it.

Anyone have any knowledge of the effectiveness of this stuff? Or have any other alternatives in the price range. I just cant stomach the insane price for some of those premium sound dampeners. This stuff is around $150 for 100 square feet! In fact if anyone in Toronto area wants in I think we could do a bulk buy.

Pass on ashpalt based. For a low price deadner try Rattle Trapp 80 mil. It works well and even holds up in southern heat. They have some ashpalt based also so be careful. If you go to ebay or amazon and type in rattletrapp 80 mil, the correct stuff will come up and is sold directly by them.

Ya ive been told to avoid the asphalt stuff for smell and excessive weight. But B-Quiet is apparently butyl based? And still crazy cheap. Ill check out Rattle Trap though.

Nope says asphalt right on their site, my biggest beef is it will fall off the roof and trunk lid in hot climates, I have tried it btw if wondering. Rattletrap isn't te best out there by any means but it's the best cost to perf ratio I've found personally.




Double checked I guess ultimate is butyl now, so that would prolly be alright, not as thick at 60mil but may not matter to ya

www.raamaudio.com they have a couple of packages that offer the butyl mat and peel and stick ensolite foam. The small package would be enough for most people.

http://www.raamaudio.com/package-1-2...-41-625-sq-ft/ $160 for the small package, the larger one is $240.

I got samples from be-quiet , left it in the car for a week on the passenger seat. It was all melted and sticky , don't waste your money on that garbage .

I used to use b-quiet. It cut up my hands from time to time and it was really sensitive to the surface it was adhered to. You can get it to stick to anything, you just had to clean it really well and roller the hell out of it. Multiple layers upside down never worked though.

I switched to raammat a few years ago. That stuff is alot easier to work with.

Do you think one package 2 would be enough Raammat to do a full set of skins with enough left over for the trunk lid?

Here's a forum vendor for sound dampening. May be worth a look:

I also have some Audio Technix sound dampening I'm installing when I do my doors.

Thanks for all the heads up guys. I will avoid B-Quiet, sounds like they have a little more work to do before they are worth my business.
Now that I've got into this sound dampening phase I have encountered lots of interesting products. Second Skin's Sludge product looks interesting for use on the floor. Anyone ever try that stuff?
Im a big fan of 1st hand reviews, you never know how many poor reviews were removed from a suppliers site to make themselves look good.

Definitely research options, different applications might need different products. Check out www.sounddeadenershowdown.com to determine what materials should be used where. The butyl/aluminum CLD sheets work for panel resonance, but other materials will help in different ways such as mass loaded vinyl, closed cell foam, etc. so in the end, you may not need 100sf of CLD, instead maybe 30-40sf and 20-30sf of other stuff.

As far as brand names, I really like second skin, really good quality.

@wheelhaus - You know that the link you have been posting is to the new version of their website... that's a storefront with a minimal scientific data.

A couple years ago, the site was a science fair of different brands and thicknesses. Test results showed noise levels, adhesion strength at temperature, etc. Very different from today.

Ever since Don started selling a product, he took down the comparison. In his words:

Stand up guy with a fine product. Most commercial products are marginally better than Peel N Seal... but the main goals are to address resonances with mass, address panel-to-panel rattles with support, and total noise levels with a damping barrier.

True, I didn't mean to direct anyone there for the old brand comparisons, more so that he has some good info describing the different types of acoustic materials. The OP looked like he wanted to purchase a load of CLD material and I simply wanted to show that other types of materials (NOT asphalt) are useful for different reasons. A lot of people seem to think CLD on everything is best, but it's not always the case. I linked that site for descriptions and scenarios where other materials may work better, re: road noise, resonance, rattling, etc.

Yup very true. I kind of jumped at the good deal but now ive really been getting down and dirty researching this stuff. It looks more like I should get 30ft of the deadener and then a little extra foam (dont want the mass loaded barrier though cause as good as it sounds I think thats just going overboard with weight)

And I thank you very much for your help! :happy0180:
