Soundproof a ceiling by adding a layer of drywall. This timing of this project depends on the size of the area that you want to soundproof. You need drywall, screws and a drill with a screwdriver attachment or a power screwdriver.Continue Reading
Decide on the kind of drywall you need for soundproofing. Common drywall works well for basic soundproofing, but if you need more significant soundproofing, you need sound-engineered drywall. If using common drywall, purchase it in 5/8-inch thickness.
One layer of common drywall works well for general use. If you want more soundproofing, add another layer. If you are using sound-engineered drywall, one layer will usually suffice. If not, you can add another layer later.
Measure and cut the drywall to the proper specifications. You should cover every inch of the ceiling for best results.
Install sound-engineered drywall the same way you install common drywall. Find the ceiling joists, then screw the drywall into place using a powered screwdriver or a drill with a screwdriver bit. A drill is also useful for making starter holes in tougher joists. If you are installing more than one layer, attach the layers one at a time.
