I was going through bookmarks and found this. It may be help for people with speakers (I just do headphones, have neighbors on both sides with a townhouse). If you're use these with Quietrock, which absorbs 7 times more sound than regular drywall you might get some good results. I've hung Quietrock and it's really works, Holmes on Holmes did an episode and had a sound expert measure it, really works. This screw design seems like it would be really good in a media room with it.

The drywall screw is intriguing -- they cite a 9db improvement -- but I couldn't find it in production. Apparently they are still trying to find a way: https://www.akoustos.se/.
Anybody interested in producing it? (Not me, I'm retired.)
