Does Insulation Reduce Noise?

Yes, insulation helps reduce noise both from outside and between different levels and rooms inside your home. In fact, if outside noises seem louder than they should be, it may be a sign you don’t have enough insulation.

Installing insulation for soundproofing purposes is beneficial for any home, but particularly for those living in cities or other high-traffic areas, as well as people living in apartment complexes, where noises tend to be a lot louder. Loose-fill cellulose and fiberglass insulation are the best types of insulation for sound control.

How Insulation Helps Reduce Noise

Limiting the transmission of sound from one area to another requires a material that encloses the source of the noise and forms a barrier that absorbs vibrations between the source and the adjacent areas. This is how insulation works.

Keep in mind, however, that not every type of insulation reduces noise. For example, reflective insulation such as radiant barrier, which is often installed in homes in warmer climates, works by reflecting heat from the sun. It is installed in the attic, right under the roof and helps keep your home cooler and more comfortable—but doesn’t act as a sound barrier at all.

If you want soundproofing insulation, cellulose, fiberglass and foam insulation are great choices—and they can be installed in the walls, floors and ceilings of your home. These types of insulation reduce outside noises and noises from room to room and between different levels of your home or building.

Insulation and Soundproofing: Airborne & Impact Noises

There are two different types of sound: airborne and impact. Airborne noises come from outside (traffic, voices, etc.) and also include noises from the TV, music and other things inside the house. Impact noise includes footsteps and vibrations from large appliances such as your washer and dryer. Insulation helps reduce both airborne and impact noises.
