Soundproof a home theater: Seal gaps (doors/windows/cracks/switchboards) with acoustic sealant + door sweep. Replace hollow door with solid core + rubber seals. Add mass: double drywall with Green Glue/rockwool. Use false ceiling. Add carpet + rubber mats. Install acoustic panels + bass traps. Use silent fans, insulated ducts. Test leaks and reseal.
