Soundproofing walls is simply to have a barrier to match or break through the high levels of
sound (noise) produced by outside sources.
This is to reduce the sound pressure from the sources to the receptors.
There
are ways to reduce receiving these sound waves. Some of these include
increasing the distance from source to receptors, noise barriers, and damping
structures among others. The barriers
include many products to use to absorb sound and help reduce noise.
Treatments
These
are acoustic treatments to combat your unnecessary sound problems. You need to
consider however that you need to improve the sound within your room/house and
how to reduce the leakage of sound from somewhere to your place.
Some of the
solutions in limiting these unwanted sounds (considered noise by some) would
include acoustic quieting, noise mitigation, and noise control.
The others that
include unwanted direct sound waves (reflections that can cause echoes and
resonances that in turn cause reverberations) can be reduced by a good degree
by soundproofing. The aim is to put barriers from the source to the involuntary
listener. Distance can’t be used for stationary objects (your house, for one).
Insulation
Currently,
the insulation materials used as soundproofing barrier is typically made of
mineral wool (rock wool) and fiberglass, popular choice in heat insulation
projects. Some use cotton or cellulose.
Since
the action is basically flowing along the same principles, these are basically
the same insulating materials for houses and rooms from extreme cold
conditions. The same principles govern the movements of heat in objects, places
and persons.
Materials
When
soundproofing a room, the materials used are typically rigid panel style,
mineral wool, or rock wool precuts. Usually, these are sold as panels or in the
form of softer batts, even if both are made of the same materials.
They
are made typically from mineral wool, fiberglass, cotton or cellulose made from
recycled materials. Accordingly, they are sized for their use in walls, floors,
and ceilings in houses.
Packages
These
soundproofing insulation materials like the mineral wool and the fiberglass can
be bought in packages of multiple panels. As can be expected, these materials
are manufactured with more than the expected average tolerances considering
their present type of use.
It is
very important that the fits for these materials are perfect. They have to fit
in all the cavities with friction press fit. This is to ensure that no air gaps
can be used in the leakage of sounds into unwanted places.
Panels
For
the purpose, the thicknesses of these panels are typically 2 inches by 3
inches. Because they were manufactured rigidly enough, they are easily cut for
the panels to fit into shapes around electrical outlets and studs. A drywall
saw is used to precisely cut out the notches and make each panel fit into
place.
This
is the same procedure they use in cutting out the same standard for wall and
ceilings. There is no vapor barrier needed.
Among
the list of materials available for use in soundproofing walls, the mineral
wool products are best at absorbing high-frequency sounds.
