Spring-Loaded Screw Turns Drywall Into Sound-Absorbing Panels

Whenever I read the sneering comments of "engineers" I am always reminded that they are the same geniuses who gave us the Titanic and the Tacoma Narrows bridge. 

I'll wait for actual tests. I cannot see how it will work but that by no means it doesn't. 

Click the link, look at the graph. It shows sound transmission rising from 400 to 4kHz. Has anyone ever heard sound coming through a wall? Does it sound like this? No. It is the exact opposite- the wall blocks higher frequencies more than lower. Even the graph of a supposedly normal wall is total BS.

Also, just look at the screws. Anyone ever see a drywall screw? Anyone? Beuller? What a joke. Thanks OP, but no thanks.

What is holding the drywall in place? Do you tighten it until the head is below the the surface, like a normal DW screw?

That means the panel has only one side of the drywall paper pinched with a springy thing on top of a tapered screw head through the drywall.

The head of the screw, even though it doesn't move, the dry wall actually does, from the design I see. IF the drywall isn't against the studs there is a huge loss in fire protection between studs, but also stud to domicile. I don't think it could meet fire code, to tell the truth..

I’d like to see the screw after it is applied. Its unclear what is taking place but I suspect @ millercarbon & @ oldhvymec have some good points

+1 millercarbon & oldhvymec. Most noise I hear through walls are lower frequencies. Maybe up to 1kHz., not sure.
