Sound insulation should not be confused with sound absorption - they have two different functions. This article describes sound insulation materials and different types of sound insulation materials that can be used to effectively reduce the propagation of sound energy.
When you are soundproofing the room, you can do this to reduce the noise, just by blocking the sound waves by using distance or objects to block the sound waves; or you can use noise absorption to change the sound waves by suppressing echo, resonance and reflection. . Insulating materials have damping properties that control the sound level, reducing and distorting them.
On the other hand, sound insulation is to prevent the spread of sound; reduce the transmission of sound energy to adjacent airspace. There are several different types of soundproofing materials that can be used to reduce noise and sound transmission.
A brief understanding of the different types of insulation will help make an informed decision for your family.
You can use fiberglass insulation between the studs inserted into the drywall layer and foam insulation that can be blown into the wall without removing the drywall. The same method can also be used for the floor.
You can use passive absorption to reduce sound; mineral wood insulation or acoustic foam forces the sound to change direction multiple times and travel a long distance before it can completely pass through the insulation. Each time the wave changes direction, a portion of the energy is absorbed by conversion to heat.
Lead plates are very good at blocking sound transmission; in addition, they are easy to use, cut and install. Foil-face acoustic duct wrap can be used to eliminate noise from noise pumps, generators, engines, saniflow systems, etc. Acoustic mineral wool is very useful in reducing airborne noise and can be used very successfully on walls, ceilings and floor joists. The density of the material makes it an effective sound absorber.
Before attempting to use soundproofing materials, it is recommended that you conduct a thorough study of the subject.
