Engineering gave us margarine. marketing got people to eat it when animals would not. Engineering gave us synthetic tech fibers that cost half the price of natural fiber cotton, marketing convinced people to pay more money for a product that was cheaper to make and does the same thing. Get the idea here.
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.
