Basement cinema - Sound insulation

I've never done that before. There's always a first time and it won't be that difficult.

Just watched a video, so the sealing tape takes over the acoustic decoupling. That's easy.... OK, that would decouple the stud frame and the construction is quite simple. What I don't like, however, is drywall, I'm not a fan of it. Alternatively wooden panels, are these probably rated worse again in the home cinema, but acceptable?

Hi, great project! I would be interested to know how you plan the equipment regarding the technology? Projector with ceiling mount? Screen? Best regards

Hi, acoustically transparent screen (possibly curved) and LS 7.1.4 not visible; Marantz or Arcam AV. Sony 260 or JVC 4k front in the shelf. All equipment in the adjoining room (no lights in the cinema room). Background lighting for before/after the film or for anxious children in the dark, all controlled via touch remote. Expert was just here today, when I’m back from the business trip, it will get interesting! Regards

Your last post brings me to the question: Have you ever tested if cinema volume is too loud for the bedrooms of the other residents? Maybe all of this is unnecessary?!

I initially had big concerns as well, but in the poorly soundproofed old building, even at volume levels just below the pain threshold and during a Transformers scene, something can only be heard in the room directly above. Just one room further to the right you have to put your ear on the floor to hear anything at all.

In the new building, it shouldn't actually be any worse...

House is not the same as house, old not new, etc. Each will probably be different. If I turn up the volume in the living room, the sleeping family on the first floor complains, so I assume that if I make thunder in the basement cinema, then even more so. I haven't tested it now either, it would also be a somewhat pointless test since the soundproof doors and corresponding constructions or decouplings are not yet in place.

In my opinion, it would be even more pointless to install doors and decouplings for a lot of money that one might not have needed at all.

Of course, I understand that you don't want to install a normal door first, only to replace it later. But before building a room-in-room concept, it's a good idea to set up a subwoofer first. At least if you have to watch your money a bit...
