Damping Material

Aside from the specialized damping materials produced only for hi-fis, what could possibly be some cheaper alternatives? I was thinking of the Vileda window cloth as it describes the product to have high content of natural fibres and is highly absorbent of liquid. I wonder if this would absorb heat and vibrations as well

blue-tak

 

hi penance. Are you suggesting that i cover the casing of my kits with lots of this?


regards

 

the stuff to soundproof cars might be a good alternative...

 

Any particular description of the stuff, brand name?

thanks

regards

 

havent got a clue. most classic car mags will have adverts.i dunno if it will work or not as ive never tried it. blue tac sounds interesting though...

 

thanks rob. will go tonight to car shops and ask about this.
hope this works.

regards

 

yea you could cover it, not practical tho.
as AT said, the auto damping sheets, tho the ones i have seen have bitchumen in them and i doubt you want that near a source of heat.
Cork tiles is a possibility, or copper sheet - tho that defeats the idea of cheap

 

Auto Damping materials with flammable properties is indeed dangerous. My Quad 306 is a class A amp that gets hot like an oven. If that's the case with auto materials then out this go from my list.

Dynamat.

 

Hi Henry. No flammable properties?


regards

 

Errrrrr????

Class A/B and it should not get too hot....

if you use this stuff to sound proof the engine bay of a car i would have thought it was flame retardent..still not so sure it would work for dampening hi fi though.

 

Corrections? I thought I read its spec as a class A amp But it does get hot more than the normal.

I've been trying some foamed butyl rubber, has the same feel as sorbthane, but not quite the same properties. It works well as damping and as a composite in a stiff light shelf or base for CDP.

I used 6mm MDF top and bottom to make a sandwich with the FBR.
Its a dense foam 70kg/m3 15mm thick

You can get a roll of the stuff from Decathalon

ive spiked some of my units and put them onto mdf panels with feet in an attempt to drain unwanted vibs.im gonna put inner tubes under the mdf in order to stop unwanted groundborn vibs.
could be barking up the wrong tree though.

 

What are you trying to damp?

 

i like blu tack

 

what about stuff for lining speaker walls....anybody know what else works...anybody tried the brown bread from craplin??..is that for damping walls or absorbtion of sound..?

 

Interesting article on damping here - even a little bit of theory!

I actually 'obtained' some isodamp rubber sheet to line my CDP. Seems to work very well - as it should! I think it is extraordinarily expensive, but I'll see what I can find out.
