Soundproofing Walls – Not an Exact Science as Yet

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.
