What is this dampening called?

Since this ties in with my work, I guess I tend to be pickier about my terms.

I can understand that- In my business, the number 0.12 (as half of 0.25, truncated) is referred to as "a twelfth", even the doctors say it. Drives me out of my mind! I can't bring myself to say that, so I have to say "zero-point-one-two", as no one would understand what I meant by "an eighth."

Perhaps real jute was used in autos in earlier times, and the name just never evolved down here:
Ford - Ford 1955-1979 Ford Thunderbird Jute Fiber - Macs Auto Parts

Hmm, jute was well known in all the automotive upholstery shops I've ever been exposed in Ga. and even one I used in Tampa, Fla; ditto as the premium carpet underlayment after AC became widely installed in businesses and as late as '75 was used in the Bricklin, though don't recall when it went away as part of weight reduction, just recall it wasn't in a '90 Chevy PU.

Can't recall it ever being referred to as felt, which I've always equated as a much finer, softer grade of jute, though Googling, it's now referred to as jute felt.

It's great for growing penicillin fungus plants also as we learned the hard way one hot/steamy July night in Tampa!

Jute felt is felt made from jute. That's not what is in the first post. That's standard everyday generic rag felt. I bet there is little to no jute in it. It's made form old clothing and cuttings from garment factories.

OK, I'ma gonna stop now because there is something from my industry that is hauntingly similar to what's going on here.

Remember tar & gravel roofs? They haven't used tar around here for more than 50 years, they converted to asphalt. Yet they're still referred to as T&G roofs.

Fair enough, jute it is.

Grumble.

Thanks. Now the question is rigid or loose? sonic differences between the two?
I used loose because I bought a bail, knowing I was going to use it up over the years. I don't know what you can buy for quantity of the panels but it will be more expensive per quantity but maybe cheaper if you can get smaller amounts. I have always been a believer in more product, less dense. Unless you want to talk about the lead sheet I tried. It worked but don't bother, it's a real hassle, and expensive.
