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/

Iā€™d certainly consider it for renovations and new builds.

I had the fortune or misfortune of rebuilding my house over the last five years. I went through great lengths for acoustics! I have six inches of closed cell foam in the floors. Floors are cork. Closed cell insulation in all exterior walls. Open cell in the attic! Then rolled acoustic fiberglass in all the trusses from one end to the other. Insulated all interior walls with acoustic grade fiberglass! Solid core interior doors. All double pain low e glass. All equaled an extremely quiet house with excellent bass control. A bit extreme, but while I was at it, I figured that it was the time!šŸ˜Ž
