Spring-Loaded Screw Turns Drywall Into Sound-Absorbing Panels

This looks promising for a 9db reduction in sound escape in homes.

Apparently the spring loaded screw acts as a dampener of sound vibrations that hit a regular dry-wall.In principle, the screw is split in the middle with a spring placed inside. The screw tip goes into the wooden joist, the head holds the plasterboard in place and in between a thin resilient mechanical coupling that prevents the sound waves from advancing is formed.

They have patents and are looking for mass production.https://www.akoustos.se/

I’d certainly consider it for renovations and new builds.

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..

A room must ABSOLUTELY BE COMPLETELY DEAD in order to NOT distort the recorded signal. ANY room contribution to the sound is a distortion.

<<<<<<<<<<<<<<<<<<<<<<<<<<<,>>>>>>>>>>>>>>>>>>>>>

No thanks, MUST absolutely be WHAT?

You ever been in a room like that? Maybe a speaker test or two, but to listen in a room like that.. Forget it.. You’re WAY off fella.. Horrible at best.. DEAD really does describe that type of sound.. It SUCKS...

NO room is a much better idea that THAT room.. Just sayin' :-)
