Full Answer

  1. Decide what kind of drywall you want

    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.

  2. Decide on how many layers of drywall you want

    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.

  3. Measure and cut the drywall

    Measure and cut the drywall to the proper specifications. You should cover every inch of the ceiling for best results.

  4. Screw in the drywall

    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.
