Sound is transmitted when vibrations
move through the air, floors, ceilings and walls. The sound waves move from one
room to the other, or from the outside of the home to inside. This includes
traffic noise or the sound of noisy neighbors. Insulation is a good sound
absorber and is effective at minimizing the noises entering a room.
Soundproofing consists of using a barrier of some sort to prevent sound from
entering the space that has been sound proofed. There are two basic ways to
achieve this reduction in sound: noise absorption and noise reduction.
Approaches to Sound Insulations
There are a few approaches to noise level reduction or noise absorption. A
variety of materials can be used for either purpose. Noise reduction can be
accomplished with the use of space between rooms. The more space, the more room
for sound waves to dissipate. If you increase the distance between the source of
the noise and the space, you will reduce the noise that enters the space.
The other method, noise absorption, is also referred to as dampening. With this
method, the sound waves are converted to heat within the insulation. This
increases energy efficiency, while reducing sound. It also suppresses the echoes
and reverberation of sound waves.
Materials for Sound Insulations
Rock Wool Insulation is made of all natural materials, such as diabase or
basalt. It is used for insulating the home and absorbing sound. There are other
benefits to this type of insulation. It is fire resistant and helps control
condensation. In addition, it is resistant to the growth of bacteria, mold and
mildew.
Mineral Wool Insulation is available in either batts or loose fill. The material
is stiff and brittle. Mineral wool is not only sound proof, but is fire
resistant as well.
Fiberboard Insulation is installed under the drywall in your home. This material
reduces sound waves through the walls and ceilings. It is effective for reducing
outdoor noise from entering your room. This material is an excellent choice if
you live in a city or for homes located on a busy street.
Acoustical Wall Coverings can be attached directly to the drywall. The best
material to use in these wall coverings is polyester. This material is best at
absorbing the sound waves that you are trying to eliminate.
Cork Squares look like floor tiles, but are made with cork board. The cork has a
self sticking backing that is easy to apply to the wall surface. If you like the
look of the cork, you can leave it this way. However, if you want it to match
the decoration in your house, you can cover the cork with wallpaper.
