Noise is simply unwanted sound. In the
home, most people consider noise to be just about any sound other than the
sound made by what they’re doing. 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 exactly how soundproof insulation works.
Installing soundproof insulation for
walls, floors, and ceilings:
- Drywall, (also called wallboard, plasterboard, or gypsum board), such as Sheetrock. An excellent and inexpensive source of mass, which is a key element in soundproofing. Drywall is a great cheap soundproofing material.
- Damped drywall. Drywall which incorporates a sound damping layer. You can also get the same results more cheaply by creating your own damped drywall, by applying damping compound between two sheets of regular drywall.
- Sound-deadening fiberboard. Because of their low mass, these are not the best choice for soundproofing walls, but are sometimes useful in floors as a spacing layer if additional mass is not needed. They don't provide damping, decoupling, or absorption.
Moreover, not every type of insulation
reduces noise. Reflective insulation such as radiant barrier works by
reflecting radiant heat from the sun. It is installed in the attic, right under
the roof and reflects energy from the sun, which keeps your home a lot more
comfortable but doesn’t act as a sound barrier at all. If you want a sound proof insulation, cellulose, fiberglass and foam insulation are great choices. These
types of insulation reduce outside noises and noises from room to room and
between different levels of your home or building. Fiberglass and cellulose can
be installed in walls, floors and ceilings. There are two different types of
sound: airborne and impact. Airborne noises come from outside 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 reduces both airborne and impact noises. If your walls are
properly insulated, you’d probably be surprised at how much quieter noises from
the outside seems.
Fortunately, there are a number of
soundproof insulation or noise-reducing initiatives you can take to alleviate
the problem. The most effective of these are best done during a building or
remodeling project because they involve the way walls or other structural
elements are built. Many housing experts believe that using permanent,
soundproof insulation solutions isn't necessary. This is mainly because the
performance of a soundproofing installation may not be up to the expected
levels. Then you have to tear down the existing soundproofing additions, a
situation which results in unwanted expense. Furthermore, such permanent
solutions pose a problem if the house has to be redecorated. Homeowners should
use soundproofing solutions that are affordable, effective and flexible. Unlike
professional solutions that might create the need to seek legal permissions,
easy soundproofing methods pose no such issues. You should understand that at the
core of every soundproof insulation technique lies a simple concept which sound
waves create reverberations and echoes that you need to limit.
