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.

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.
