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.

Very interesting, thanks for the heads up!

Looks as though it hasn’t entered the market just yet, but I wouldn’t think that would be too far off.

Boy, could I use something like this, otherwise I’d have to think about plywood paneling...the cost of which is crazy right now.

Huh. Looks at best like it remains to be seen. Nobody has any hard info yet on what proper installation would actually look like.

Maybe resilient channel might turn out to be more effective sound-wise anyway. Will have to wait and see.

I think I saw where they spec'd, for "steel studs", 1 per 8" on stud and every 12" "in the field" (...!) How's that for affordability.
