Before diving into the specific methods, it’s important to understand why soundproofing is necessary and how sound travels through walls. Soundproofing reduces the amount of sound that enters or exits a room, helping to improve privacy and comfort. The science of soundproofing involves reducing sound transmission through barriers like walls, floors, and ceilings.

There are two types of sound: airborne sound (such as conversations or music) and impact sound (like footsteps or banging). Both types of sound can travel through walls, but their methods of transmission are different. Soundproofing methods are designed to address both types by either blocking the sound or absorbing it.

Cheap and Easy Methods to Soundproof Your Walls

Soundproofing your walls doesn’t have to involve expensive renovations or complicated installations. Here are several inexpensive and effective methods to reduce noise transmission:

1. Use Thick Curtains or Drapes

One of the easiest and least expensive ways to soundproof your walls is by hanging thick curtains or drapes. These can significantly absorb airborne sound and prevent it from traveling through windows. Opt for curtains made from heavy materials like velvet, suede, or polyester, as these fabrics are better at sound absorption. To enhance the soundproofing effect, consider using double-layered curtains or installing a curtain liner specifically designed for noise reduction.

Installation: Simply hang the curtains over the windows and any areas of the wall where you need soundproofing. Ensure they cover the full area from top to bottom to maximize the sound barrier.
Effectiveness: This method helps to reduce noise from outside or between rooms. While it won’t make a room completely silent, it can help muffle annoying sounds, making your space quieter.

2. Apply Acoustic Foam Panels

Acoustic foam panels are a popular and effective solution for soundproofing walls. These panels are designed to absorb sound waves and reduce noise reflections, especially in rooms with hard surfaces like concrete or plaster. Acoustic foam can be particularly effective for reducing echo and minimizing sound transmission between rooms.

Installation: Acoustic foam panels are easy to install, as they typically come with adhesive backing or can be attached with nails or screws. Place them strategically on your walls, particularly in areas where sound is likely to enter, such as near windows or doors.
Effectiveness: Acoustic foam is great for absorbing sound within the room. It is particularly useful in reducing echo and reverberation, but it is not as effective at blocking sound from entering or leaving the room.

3. Use Mass Loaded Vinyl (MLV)

Mass Loaded Vinyl (MLV) is a dense material that can be applied directly to walls to block sound transmission. It is particularly effective at reducing airborne noise, such as voices and traffic sounds. MLV is often used in professional soundproofing applications, but it is also available in easy-to-install rolls that can be applied to residential walls.

Installation: MLV can be nailed or glued directly to the surface of the wall, then covered with a layer of drywall or another type of finishing material. It’s important to apply the MLV as tightly as possible to avoid gaps, which could allow sound to pass through.
Effectiveness: MLV is one of the most effective soundproofing materials available at an affordable price. It works by adding mass to the walls, which helps to block sound from passing through. It’s particularly effective at reducing low-frequency sounds like bass or traffic noise.

4. Seal Gaps and Cracks

One of the simplest and most cost-effective methods of soundproofing is to seal any gaps or cracks in your walls. Even the smallest openings can allow significant amounts of sound to pass through, so it’s important to ensure that all seams, cracks, and joints are properly sealed. Use a combination of caulk, weatherstripping, and acoustic sealant to fill in these gaps.

Installation: Inspect the walls for any visible gaps, especially around window frames, doorways, and electrical outlets. Apply a generous amount of acoustic sealant to the cracks and smooth it out with a putty knife. For larger gaps, weatherstripping or foam tape can be used to fill in the spaces.
Effectiveness: Sealing gaps is one of the most effective ways to prevent sound leakage. This method works particularly well for blocking low-frequency sounds, such as traffic noise or voices, from entering or exiting the room.

5. Add a Layer of Drywall

Adding an additional layer of drywall to your existing walls is a great way to increase soundproofing, and it doesn’t have to be an expensive process. The added mass from the second layer of drywall will help to block sound transmission between rooms or from outside. For even greater soundproofing, consider using a special type of drywall, such as soundproof drywall or quietrock.

Installation: This method is more labor-intensive than some of the others, but it is still a relatively affordable option. To install an extra layer of drywall, apply construction adhesive to the existing wall and then attach the drywall sheets using screws. Be sure to seal all edges with caulk to avoid sound leaks.
Effectiveness: The additional mass from the extra drywall will help block more sound than a single layer. This method is effective at reducing both airborne and impact noise, but it may require more time and effort than other methods.

6. Use Bookshelves or Furniture

If you are looking for a quick, inexpensive solution, placing bookshelves or heavy furniture along shared walls can be an effective soundproofing technique. These items add mass to the wall and can help reduce the amount of sound that travels through the wall. Bookshelves, in particular, can be great for absorbing sound, as books act as natural sound absorbers.

Installation: Simply move large, heavy furniture items (such as bookshelves, cabinets, or couches) against the walls that are the main source of noise. Fill the shelves with books or other heavy items to maximize the sound-absorbing effect.
Effectiveness: This is a temporary and somewhat passive method of soundproofing, but it can provide noticeable results without any cost or major installation effort.

7. Install Soundproofing Wallpaper

Soundproofing wallpaper is a relatively new and innovative solution that offers a sleek, easy-to-install way to reduce noise in your home. This wallpaper is made with soundproofing materials that can help absorb sound and reduce noise levels. It can be applied just like regular wallpaper and is available in a variety of designs and patterns.

Installation: Soundproof wallpaper is applied in the same way as regular wallpaper. Simply measure your walls, cut the wallpaper to size, and apply it using wallpaper paste or adhesive. Ensure the edges are sealed to prevent sound from seeping through.
Effectiveness: While soundproofing wallpaper is a less powerful solution compared to other methods, it can still help reduce noise in your home. It is particularly effective at reducing higher-frequency sounds and providing a smoother finish for your walls.

8. Use Rugs or Carpets on the Floor

While this method isn’t directly related to walls, using rugs or carpets on the floor can complement your overall soundproofing efforts. Soft materials like rugs absorb sound and reduce the amount of noise that bounces off hard floors, preventing it from traveling through walls.

Installation: Lay down thick, plush rugs or carpets, especially in high-traffic areas or near walls that share noise with other rooms. You can also use foam underlayments beneath carpets for added soundproofing.
Effectiveness: This method reduces the amount of impact noise, especially in apartments or homes with hard floors. It can also help reduce echo in rooms with lots of hard surfaces.

9. Use a White Noise Machine

Although this method doesn’t block sound directly, it can mask unwanted noises, making them less noticeable. White noise machines generate a consistent, neutral sound that can help mask external noise from traffic, neighbors, or construction. They can be especially effective in bedrooms or areas where you need to create a peaceful, quiet atmosphere.

Installation: Simply place a white noise machine in the room where you need to mask sounds. These machines are portable and easy to use, making them an affordable solution.
Effectiveness: White noise machines don’t stop sound from entering your space but can help make distracting noises less noticeable. This can improve the overall acoustic experience of a room.

Conclusion

Soundproofing your walls doesn’t have to require expensive materials or a lot of effort. By using simple and affordable methods like thick curtains, acoustic foam panels, sealing gaps, or adding furniture, you can significantly reduce unwanted noise in your home. While no single method will make a room completely soundproof, combining several of these strategies can lead to noticeable improvements in your living space.

Ultimately, the key to successful soundproofing is understanding the source of the noise and choosing the right methods to address it. With these cheap and easy solutions, you can create a quieter, more comfortable home without breaking the bank.
