Best Tips For Soundproofing Your Apartment Walls

It is always  fun  to hear and play music within our rooms in the home or even at offices at leisure. But there can be people around that room who don’t love to hear the type of music you’re playing. At the time, it may also happen that he/she doesn’t love music at all. Eventually, a huge problem and quarrel will arise from this, and we should not collide our means of happiness with other people’s disturbance. Soundproofing is the ultimate solution to this problem. It requires some basic knowledge on the propagation of sound and the suitable procedures. Below here, we have given you an insight into this so that you can know the best tips for soundproofing your apartment walls.

 

Importance of Soundproofing

The procedure of soundproofing has several benefits which are as follows:

  1. Prevents from disturbance due to sound propagation

Now, as a music composer who regularly works in his studio will not want sounds from other disturbing his recording or practice. Moreover, the people in other rooms will also be disturbed by his playing. Soundproofing technology fits perfectly to this situation where it will prevent sound propagation from the place to outside and vice-versa.

  1. Ensures a perfect environment for recording and composing

Soundproofing will ensure an environment where a song-writer or a music composer can easily do their recordings and compositions in a suitable environment. There won’t be any disturbance from outside.  

  1. Human health and safety

Excessive noise level is not only harmful for the environment but also detrimental to human health. If you are careful enough about your health, you should install sound proofing and it will help to reduce the noise level.

 

How does sound propagate through walls?

 When a source produces sound, a portion of the incident sound energy is reflected from the wall, and the wall absorbs some part of it. Eventually, some portion is passed through the wall. Usually, the sound is reflected from surfaces because various media have different densities or impedances. The sound waves have to tolerate this impedance or blockage and then propagate through a wall.  

 When sound tends to encounter the gaps between the studs, it is transformed into airborne noise. When sound heads to propagate from one medium to another, some of its energy is lost in the way of transformation, and some of it returns to the original medium.  Generally, the quantity of energy which is dissipated at the linkage of two media depends on the magnitude of the variation of impedances between the two media. This implies that the larger the variation between the impedances between two media, the lesser the quantity of acoustic energy will be able to transmit across the linkage or boundary. 

 The incident sound wave is converted into airborne noise which propagates through the wall into the surroundings. The acoustic impedance between drywall and the studs is not as large as that between drywall and air. Thus, a fair amount of acoustic energy will be transmitted through the wall at the stud spaces. Since the surface area of the studs is not too big, the magnitude of the noise passing through the studs may not be as large in comparison with the magnitude of the noise propagating through the drywall. 

 

What are the fundamental principles of soundproofing the walls?

 The procedure of soundproofing will depend on the following four essential points:

 

  1. Mass

The very first principle of soundproofing is mass. Mass hinders the transmission of sound. We all know that it is more difficult for the sound to move through a heavy object than a light one.

 

  1. The process of mechanical isolation

This one of the most important among the four basic principles of soundproofing the walls. The sound clips, rigid channel and the studs inhibit the passage of sound from one side of the wall to other through mechanical mediums.

 

 

  1. Creating a blockage so that sound cannot go out
Construction of an insulating wall or ceiling can enhance the sound loss by pulling down the intensity level. Another benefit of insulation is the lowering of the resonance of decoupled walls.

 

 

  1. Damping

Damping means the reduction of resonance within the room by absorption or diffusion. Absorption will help in reducing the overall sound level produced by the source. Moreover, redirection makes the noise harmless by reducing coherence.

 

 

The procedure of soundproofing the walls

 

Everyone doesn’t have the same necessity. Someone may have decided that he or she will soundproof the existing wall. On the contrary, someone may also want to build a new soundproofed wall.

 

Let us now see how to soundproof an existing wall.

 

 

How will you soundproof an existing wall

 You have to examine your wall well before you try to soundproof it. You should keep playing a sound inside the room and then go for checking the weak spots on the wall. Also, You must search for any perforation, gaps on the wall, ceiling and along the floor.

 Here are the steps you should follow gradually to soundproof an existing wall:

 

1)Blown Insulation

 Blown insulation is a very effective process to soundproof an existing wall. This type of insulation is composed of a material with a low density which can reduce the propagation of sound waves. The material reduces the echoes which the airborne noise produces. The blown insulation is easy to install on an existing wall. You need to access the gaps between the walls for the installation of blown insulation. This procedure is also a very affordable and effective one.

 

2) Installation of more drywall

 The situation may arise where you don’t want to remove the drywall. But you can build a more drywall to improve the absorption so that sound propagation can be stopped more easily. By putting an additional layer of drywall on the pre-existing drywall, you’ll enhance the mass of the walls, and thus, you will be able to block the sound from passing.

 

3) Sealing of the Gaps

Soundwaves travel through all the possible exit points they face, such as the gaps and the perforations in your walls. The cracks don’t have to be larger for a large quantity of sound transfer, in order to block soundwaves, seal the gaps in your walls.

 

Use an acoustic caulk for sealing up of the gaps around the window shields and holes in the walls. You should also seal up open space surrounding the outlets by the installation of simple plate insulation on the wall.

 

Once you are done with sealing up of the gaps, your walls will be more air-tight, which will make it harder for the soundwaves to pass through the walls.

 

4) Use of Soundproofing Fabrics

 This is one of the easiest ways by which you can soundproof your existing wall. The main thing here is to suspend a soundproof fabric over the wall. There are two effective options for this method:

 

1) Application of Soundproof curtains

The soundproof curtains will help to eliminate a good level of obtrusive noise. Since these curtains are made from concentrated fabrics and can soak up soundwaves, these will prevent the flow of noise.

 And who doesn’t love the aesthetic look of their walls? These soundproof curtains come in different colours which will give a vibrant look for your walls.

 

2) Installation of Acoustic Foam Panels

 The acoustic foam panels which are available can absorb sound waves. This indicates that they can reduce the degree of noise which passes through your walls. At the same time, they also increase the sound within the room where they are attached.

 These acoustic foam panels are a versatile option for soundproofing because they only don’t hinder the passage of noise, but also they spread those waves into the form of heat. Thus, they operate as a thermal insulator too.

 

 

How to build a soundproof wall?

 By following these steps, you can easily build a soundproofed wall.

 

1) Framing of the Wall

It is very important to construct a frame for your wall with the studs 15″ apart if you are using usual insulation. To add any required decrement in sound propagation, you should leave a 2-inch gap between the wall and the double doors. Remember to fix a stud along with both the seams of drywall. This will make the seams look neat and clean.

 

2) Cutting of drywall as per dimension

 Firstly, cut two layers of drywall according to size.

 For cutting the drywall, you can use a rock knife. Then, you need to lay the board over an elevated surface for breaking the seam. It can also be cut by using a saw or a power tool.

 

3) Building initial layers of drywall

You should attach the first layer of drywall with the frame keeping the screws each 14″ or so. Then fix all the sealants with green glue. Now, place the second layer of drywall for easy fixing to the wall and wiggle two tubes of green glue onto the layers.

 

8) Caulking of the seams  

 This has to be done correctly for proper finishing; the taping and mudding of the seas should be done appropriately for an excellent visual appearance.

 

What to look for while buying a soundproofing material?

 You should consider these aspects while buying the materials to soundproof a wall:

–      The Materials that are more concentrated in their composition will make it more challenging for sound to propagate through by throwing more barriers for the noise.

 

–   Softening of the hard surfaces is very important for the effective soaking up of sound within a room. This softening effect can be gained by the installation of the foam panels and the application of specially made tiles to the larger surface areas such as floors and ceilings. Foam panels are usually fitted for the detachment of the wall between rooms for preventing the circulation of noise. Soundproofing foam tiles can also be cut as per the required dimensions.

 

–    You can buy soundproofing sheets to complete with a good collection of materials. Each of the materials has excellent sound absorption quality. And the majority of these kinds of sheets also have adherent backing for a secure attachment to the machinery.

 

Conclusion

Soundproofing technology is one of the most useful things nowadays for the musicians and the people who love music. You may be strangled while searching for the best soundproofing arrangements in your home or studio. We think you have got a proper insight into this procedure from this content. But above all, you should assess your environment and then decide as per your need.
