Spring-Loaded Screw Turns Drywall Into Sound-Absorbing Panels

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

The only thing i can add is that you could use those for a false wall in front of your existing wall filled with 6 inches of insulation to really deaden the sound a massive amount.

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


It looks like the big threads near the head of the screw bite into the drywall and that is supposed to support the drywall, seems kinda scetchy to me.

It states right on their website “Tested” and
”Profitable”.
I’m in.

Let's think this through. 

The drywall is already tightly screwed to the studs or joists.  The drywall will vibrate based on the dampening effect of the studs or joists, the thickness of the drywall and the size of the open area of the drywall that is not secured against the joists / studs.  Any loosening will just allow the drywall to vibrate even more since it will lose the dampening effect of the joist / stud.

Rather than trying to use the walls to damp reflections, why not try complex diffusers.  Lots of different kinds.  My favorites are artificial Ficus trees.  5 footers work well in my room.  They are about $40 each purchased from the "At Home" store.  I bought about 15 of them and they have killed the sonic problems in my room except for a slight bloom in a narrow band of the bass.  Other A'goners have reported similar positive results.
