The inventor claim that these drywall screws reduce through the wall sound levels by 9 decibels, it’s not yet on the market though. :thinking:

“The Revolutionary Sound Absorbing Screw - in short, the Sound Screw - can accomplish sound insulation many people ask for. It is easy to use. Replace your regular screw with a Sound Screw and your problems with unpleasant sound is solved, without adding extra building materials or extra work. It is tested with amazing results. When mounted the Sound Screw provides a resilient connection between panels and studs in a way where a substantial part of airborne as well as impact sound can be absorbed by the screws.” akoustos.se

I think anything with screws already was invented in the 19th century. It is an idea, but I would guess that the wall will react too slowly, or even then resonate?
