Tonto,

Be sure you can get your money back when it doesn't work as well as they claim.

Naturally, one's always a bit suspicious of claims made by someone trying to sell one something.

It does have a data sheet and testing, which is a step above most products we buy related to audio....

Different product and company, but QuietSolution offers coatings, adhesives, sealant, drywall, and wood with sound isolation in mind.

Mentioned here http://www.audiocircle.com/index.php?topic=8886&highlight=quietwood and their website is www.quietsolution.com.

STC = sound transmission coefficient and is measured in dBs.

Typical walls run about STC = 30, insulated walls about 45.

Tonto and CJ,

It's not that they're "selling something" as much as how poor the specs are. All they offer is "reduces sound transmission and reflection by 30%" which ignores that absorption and isolation are entirely different things. And who cares what it does at 500 Hz? What matters is how it affects the entire range. You can get a 30% reduction at 500 Hz with a piece of heavy cardboard. Really.

I have no financial stake one way or the other. But I'm tellin' ya, this stuff will not do anything useful for you acoustically.

Agreed.
