Whether you have already built your dream home theater and want to add soundproofing or if you are just at the exciting planning and design stage, it is important to think about how you can soundproof your room and there are some important questions to think about. With our useful overview you can soon get your favorite movies, music and sports matches blown up in surround sound.
Room space & design
If your home theater is located downstairs in your home, which is likely in most cases, you must consider that the sound escapes through the roof to the bedrooms above and through the walls to the other residential areas of your house. The basic considerations to begin with are how are the walls constructed - are they dry walls or solid blocks and bricks? Most interior walls in modern houses will be built with 2 to 4 woodworking, and depending on your location and local climate, the tapping can be filled with heat-insulating, and finally a half-inch thick plasterboard is nailed to stud work and obtained a thin finish.
This set does little to prevent sound transmission even in the walls that are filled with insulation. The reason is that the sound does not transmit well through air and it is actually the timber frame of the wall that drives the sound through the walls into the next room. It is the same principle for roofs with noise transmission through the roof timber beams and the upper floor upstairs.
Home Cinema Soundproofing Solutions
The best solution for soundproofing your home theater is a process called decoupling. The solution works by building two separate wooden walls with a noise that blocks the air gap between them to keep the walls of your home theater and the next room completely separate. This solution easily offers the best option for eliminating bass and vibration that escapes into other rooms. The downside is that you will probably lose a good foot space in your room to add the extra wall and intermediate space.
Apart from decoupling, you can add additional degrees of sound insulation by increasing the mass and dampening the wall surfaces so that they do not vibrate. The most common way to add pulp is to double the plasterboard on the wall to create a heavier surface for the sound to penetrate. This approach will technically only achieve a noise reduction of 3dB, but everything a little helps.
The final solution for adding the mixture is cushioning. Attenuation is the process of reducing vibration and the best current way to achieve this is by adding a specially designed plasterboard that absorbs sound and vibration via an internal viscoelastic compound. The special damping card is available from a number of manufacturers and ranges from half an inch to one inch thick cardboard.
The best home theater sound insulation will use a combination of all three processes.
