Soundproofing Tips

Windows

• Windows leak sound far more than walls, and are the first consideration when looking at soundproofing a room. Several strategies can be employed. The most basic is to use heavy drapes over the windows. The more material that can be placed between the room and the window, the more sound will be deadened. This is a stopgap solution, however.

  The best way to soundproof windows is to install double-paned windows. Some companies make special soundproof double-paned windows that can be used; otherwise, you can install a second window behind or in front of the current window.

Doors

• Doors are next consideration for soundproofing. Common hollow doors pass sound readily; replacing the doors with a solid wood or MDF (medium density fiberboard) will help significantly. After replacing the door, add a sweep, a metal strip with a piece of rubber, to the bottom of the door, and soundproof closed cell foam around the edges of the door frame.

Walls

• There are several options for soundproofing the walls. Adding insulation is one strategy, as is hanging soundproof foam on the walls. The best option, while complicated, is to build a second wall about a foot out from the main wall and fill that space with heavy soundproof foam. If you follow this option, do it to the ceiling as well.
