I am planning to renovate (gut the old and build new) a room in the basement to use as a home theater. It will also be used as a guest room and a bedroom for night workers with small children =) So the idea is that it should be quite soundproof.
Conditions:
The room is located in the corner of the basement, right under the bedrooms...
Ceiling and floor are concrete, walls are lightweight concrete. Two sides are exterior walls below ground. A small window at head height on one of the exterior walls. Below the window is a water-based radiator. No door to the room, only an opening that needs a solution. The room is approximately 3.1 x 5.3 m and 226 cm ceiling height.
Own thoughts:
Floor: Carpet.
Walls: Frame with steel studs a few cm from the exterior walls, insulate (unclear with what) then OSB and drywall.
Ceiling: Option 1: frame and install ceiling tiles. Option 2: framework for sound-absorbing panels. Option 3: like the walls - frame, insulate, OSB, and drywall. No plans for downlights in the ceiling but rather in a dropped section along the sides plus LED strips.
Door opening: Sliding door that recesses into the interior wall.
Goals:
Soundproof so that movies can be watched without disturbing too much. Should also be able to sleep (without earplugs) during the day when the rest of the family is awake and making noise upstairs.
Use a cost-effective solution. I'm happy to do the work myself =)
Questions:
Am I thinking along the right lines regarding soundproofing? What materials should be used? Other thoughts or ideas? Have I missed anything?
Grateful for help =)
