The Best Way to Soundproof a Wall Between Rooms

Some sound proofing products look like egg carton foam.

The easiest time to soundproof a wall is during construction, when soundproofing can be hidden within the wall. Several options are available for soundproofing existing walls as well. Many products resemble egg carton foam or Styrofoam.

Existing Walls

If you have proper access, products like soundproof wallpaper or acoustic tiles can be applied to the surfaces of both sides of a wall. Many products designed for soundproofing existing walls can reduce sound transfer by up to 75 percent.

New Construction

Before installing drywall, install your choice of sound proofing materials between the studs that divide the two rooms. A wide variety of in-wall sound proofing products can be found locally or on the Internet. The majority of in-wall products come in sizes that fit snuggly between standard stud spans. The standard open span space between wall studs for an interior wall is 14 and a half inches. The length of in-wall soundproofing products will come in either 4-foot or 8-foot lengths.

Tips

When shopping for sound proofing products, purchase fire safe products. Some may be highly flammable, such as polyurethane, polyether, and polyester foam products. Using these types to sound proof the walls in your home may also effect the price of your home owners insurance policy.
