Full Answer

Rockwool is a natural material that is available in the form of insulation batting and stuffs easily between the regular studs in a wall. Compounds and sealants work best when sprayed between sheets of drywall or caulked in small cracks and openings. Soundproofing drywall has an increased mass and density compared to standard drywall, and attaching it to resilient channels instead of wall studs further reduces noise transfer. If remodeling is not an option, acoustic foam panels install on top of existing walls or ceilings. Thick windows and special blackout curtains reduce noise from outside.
