Windows are one of the biggest causes of noise inside the home. Single glass frames and wooden window frames are the main culprit for this noise. Replacing your windows with double pane glass can be expensive. However, you can create a removable plug to block sound in your room. First, measure the size of the windows you need to soundprooff for the size of a 2-inch thick soundproofing mat. Retailers such as soundproofing.org have mats specifically for this purpose. You can also consult your local D.I.Y. store, which may have a similar product. Cut the mat so that it fits very tightly in the window. You can attach a cabinet handle to the back to make handling easier when you put it in and out of the window frame. You can remove the plug during the day to allow light to enter the room, and put it in at night to block noise while you are sleeping.
If your attic is not insulated, that can be a major cause of your sound problems. By adding extra insulation, you will not only reduce noise in your home, but also save money on heating and cooling bills. Insulation comes in either batts or rolls, and is most commonly made of fiberglass, although you can also find mineral, plastic, cotton and wool variations as well. You can buy insulation at stores such as Home Depot. It is sold in batts and rolls in sizes that are standard to most attics. Another option is to use blown insulation, but this requires professional installation.
Home furnishings play a major role in the way sound travels in your home. Each room should have at least 25 percent of the square footage covered in carpeting or rugs, wall hangings, furniture or curtains. If your main living areas have hardwood floors, consider buying a large area rug to drown out the sound of footsteps, televisions, talking and other noise. You can also invest in long drapes for your windows that will not only muffle outside noise that comes through the windows, but will also prevent sounds from bouncing off the walls. For rooms above a living area, install carpeting and a noise-reducing foam beneath the carpet, or at least lay down a large, thick area rug to reduce the amount of sound that travels through the floor into the room below.
Extra drywall is also a great do-it-yourself soundproofing idea. In rooms that face loud areas such as busy streets or highways, an extra layer of drywall can make a big difference.
If you have a home theater system, consider buying a home theater soundproofing kit. You can find these online at sites such as ProAudioAcoustics.com. or at electronics stores that sell home theater supplies, such as Best Buy.
Websites such as SoundIsolationCompany.com sell a large variety of soundproofing products and offer tips on what products are best for particular uses.
