• Method 2 of 2: Build Soundproof Structures
• Tips
• Warnings

1 Attach soundproof curtains or thick blankets to the walls. Blankets will help muffle the sound a bit. If you are willing to spend more money, buy special sound-absorbing curtains.

• If you have thick insulated walls, you won't feel any difference.

2 Place bookshelves against the wall. This will make the walls thicker and improve the soundproofing of the room. Place as many shelves and books as possible to create a sound barrier. Plus, you'll have a great library.

3 Secure any rattling items. Has it ever happened that many objects began to vibrate in your room when a neighbor turned on the music very loudly? Yes, that's why you need to fix all vibrating things (for example, speakers). You may find special anti-vibration mats useful.

4 Install the threshold seal. Nail the rubber band to the base of the door so that there is no gap between the floor and the door. If the gap is very large, nail a piece of wood to the door first.

5 Buy custom acoustic panels. Buy panels measuring 30 by 30 centimeters with a depth of 5 centimeters. They absorb high and low frequencies well.On some panels, glue is initially applied, so all that remains is to remove the protective plastic. If the panels you purchased do not have an adhesive surface, apply adhesive from a spray gun and glue the panels to the ceiling and walls. You can cover the entire surface or just individual areas - it all depends on what kind of sound insulation you need. The panels will save you unnecessary sounds inside the room and give you the silence you need especially if you have a mini studio.

• Use fiberglass panels covered with a perforated polyester film. Such panels absorb more sound than similar expensive panels. They are worth their money.

Method 2 of 2: Build Soundproof Structures

1. 1 Use dense material. The denser the material, the more sound it will absorb. Drywall with a thickness of at least 1.5 centimeters is suitable.
   • If you want to seal an existing wall, make a framing wall, attach it to the wall of the room, and install drywall on top of it.
2. 2 Leave a gap between the walls. When sound hits an obstacle, it is partially absorbed and partially reflected. Enhance this effect by building a wall with two layers of drywall and leaving a gap between them. This effect is called decoupling.
   • Decoupling impairs the ability of the wall to block low frequencies due to resonance with the wall. If the gap is 2.5 centimeters or less, sound absorbing material should be used.
3. 3 If you want to make a drywall partition, consider the placement of the fixing nails. Usually the wall is knocked down with one row of nails in contact with both surfaces. Sound travels over these nails with ease, which negates all the soundproofing work. Place the nails differently when constructing the wall. For example:
   • Double row, each on its side. This is the best way in terms of sound insulation, however, for this, the distance between the two sheets of drywall should be quite large.
   • Intermittent rows. First you need to drive in a nail from one side, then from the other.
4. 4 Use sound insulating supports or clamps. They are placed between nails and drywall to create an additional barrier to sound. There are two options:
   • Soundproof mounts (clamps) absorb sound very well with rubber construction elements. Put nails on them, then a spacer, and then attach to the wall.
   • Anti-vibration mount is a metal mount that reflects sound. Attach it to the wall with nails or screws. This will muffle high frequencies, however, this design does not cope with low frequencies.
   • Remember that spacers alone will not help you soundproof the wall.
5. 5 Fill drywall walls with sound-absorbing compound. It will absorb sound and turn it into heat. The sound absorbing compound can be placed between walls, in the floor and in the ceiling. Unlike other methods, low frequency noise will be absorbed here. This method is ideal if you plan on playing music with powerful bass or watching a movie in your home theater.
   • Sound absorbing compound is also known as sound absorbing or viscoelastic adhesive.
   • Sometimes you need to wait a few days or weeks for the composition to start working at full strength.
6. 6 Isolate the room with other materials. Sound absorbing compound is one of the best insulating agents, but there are others.
   • Fiberglass is a cheap and effective method.
   • The foam does not provide sufficient sound insulation. It is mainly used for thermal insulation.
7. 7 Fill cracks with acoustic sealant. Even small cracks in the material can compromise sound insulation. A special acoustic sealant (putty) will fill these cracks with an elastic material that will repel sound. Walk it over all the cracks, and also process the seams at the base of the walls and windows. Remember the following:
   • Water-based sealant is easier to clean.If the sealant is solvent based, make sure it will not damage the finish.
   • If the putty is different in color from the walls, choose a sealant that can be painted over.
   • If the cracks are small, it is better to use a regular sealant, because the acoustic one is more difficult to work with.
8. 8 Soundproof the floor and ceiling. The same materials are suitable for the floor and ceiling as for the walls. Most often, one or two additional layers of drywall are laid, smearing them with viscoelastic glue. You can cover the floor with a sound-repellent rug and then lay down a regular rug.
   • If there are no rooms under you, you do not need to do soundproofing of the floor.
   • If you have a concrete ceiling, plasterboard with ductile adhesive won't do much good. Better to leave a gap between the two layers of drywall or fill it with fiberglass.
9. 9 Install sound absorbing panels. If your room has poor soundproofing, sound absorbing panels can be used. There are inexpensive options, but the more expensive ones are more effective.
   • Attach the soundproofing using secure fasteners.
10. 10 That's all. We hope you managed to realize your idea.

Tips

• Get rid of the cellulose tiles on the ceiling. It only reflects sound.
• Seal all gaps from lamps and other objects, as well as the suspended ceiling around the perimeter with sealant.

Warnings

• It is possible to mount heavy structures on walls, ceilings or floors only under the guidance of an experienced craftsman.
• The classical system for calculating sound insulation is not always useful. It does not take into account noise quieter than 125 Hertz, which includes music, traffic, aircraft and construction.
