Home theaters require soundproofing. "This is accomplished through the use of specialized, noise-rated components for walls, floors, ceilings and windows," says San Francisco architect David Seidel. He also explains that many people confuse soundproofing and acoustics. "Soundproofing really only refers to all those materials and methods that will keep rooms isolated from one another. There is nothing inherently 'acoustic' about that. For rooms where homeowners want to have a pleasant acoustic experience — living rooms, dining rooms, bedrooms or home offices — a lot can be accomplished through the strategic placement of rugs, drapes and plush furniture."
