Soundproof A Room Cost

How much does it cost to soundproof a room?

Whether you need to reduce the volume of noise outside of the home, or whether you require the elimination of sound occurring within the structure (such as a shared wall in an apartment or condominium complex) there will be a few ways that effective soundproofing can be done.

For example, the homeowner converting a large living area into a home theater will usually hire a contractor to enhance exterior walls with framing, a bottom plate, and alternating studs that provide an excellent sound barrier. This is something that would cost $40 to $50 per hour in labor expenses alone. For the purpose of this discussion we will consider the options and estimated costs for soundproofing a single room in the home. This room will measure 20'x12' and will have two windows and a single door. This is a project that can be either a DIY or a professionally contracted one, and cost variations will be quite significant due to the hourly charges for labor.

Cost breakout

Generally, the typical soundproofing costs will include:

  • Walls and ceiling - according to WiseGeek.com a homeowner could use everything from carpeting to paneling to dampen noise from the outside. They recommend using textured materials in order to further reduce sound transfer. A single sheet of 4'x8' textured wall paneling suitable for the project would cost roughly $33, and the project would require 504 square feet for the walls along with another 240 square feet for the ceiling, translating to 25 panels or $825;
  • Windows - if the windows in the home are out of date and not well sealed they will allow a great deal of sound to enter the room. This might be through exterior noise or through air flow around the seals and either way it will be a good idea to also replace them in order to create a soundproof environment. The cost for the average replacement window will be between $300 and $700, but energy efficient models will also come with financial rebates; and
  • The Floor - if the flooring is already carpeted the amount of sound absorbed by this material will be substantial, but if it is covered in another material such as wood, tile, or linoleum there may be the need to cover this with padding and carpeting in order to eliminate sounds created by vibrations and adjoining homes or rooms. A high-quality carpet and pad will usually average around $19 to $40 a square yard installed, meaning that the room described would require around $1080 for carpeting.

Additional considerations and costs

  • Textured paint - one great way to reduce the costs of a soundproofing project such as the one described here is to rely on textured paints to serve as sound absorbers. For example, a heavily textured ceiling treatment may provide almost as much sound absorption as sheets of acoustic paneling, but will come in at only a fraction of the total costs; and
  • Hangings - it is important to also remember the benefits of hanging heavy drapes or fabric panels over windows and exterior walls in order to help limit the amount of noise coming into a room from the outdoors.
