9 Ways to Soundproof a Room With Thin Walls

Here are some of the cost-effective ways to soundproof your wall

1. Weak Points of the Walls

The weak points in the wall are where the noise is going to penetrate. Finding these weak spots is crucial in your soundproofing.

Also, identifying the type of noise (whether impact noise or airborne noise) will give you an idea of where to install soundproofing materials.

2. Seal the Whole Space

Going back to sound basics, the more space is filled with furniture; there will be more recipients of noise.


If the noise is coming from the outside, it will not completely stop the sound but remove the reverberating effect when it hits the wall.

The same thing will happen if the noise is from the inside. That’s why acoustic rooms fill up a space to get away with the echo effect.

3. Use Blankets or Curtains

An acoustic blanket or soundproof curtain is an effective means of reducing noise transmission through your thin wall.

Sometimes called blackout curtains, thermally insulated blankets, moving blankets, or sound insulation window drapes, these fabrics are specialized cloths that are designed to soak sound, giving you a quieter room.

4. Install Foam Mats


Foam mats are sound-absorbing soundproofing materials you can use on thin walls. Primarily seen in acoustic rooms like a radio booth or recording studio, foam mats can also be placed in your space by attaching them to the thin wall.

5. Acoustic Foam Panels

These soundproofing materials are similar to foam mats, but they are designed and fully dedicated to absorbing sound waves.

They are not sound blockers, but the fabric and foam material dilute the sound for clarity and enhancement. Having an acoustic panel made of foam adds soundproofing to your thin wall.

6. Add an Extra Layer

So you already have an existing soundproof thin apartment wall. Adding another “thin” layer can make the walls thicker.

The concept of mass and density play around with soundproofing when the barriers become thicker.

7. Use Soundproof Drywall Paint

Though not as efficient and robust as other soundproofing materials, soundproofing paint can be used to cover spots or holes to seal air and prevent any space for sound from passing through.

8. Apply Mass-loaded Vinyl

This is a special sheet designed for acoustic purposes. It is a soundproofing material flexible enough to roll out and placed in between drywalls. MLVs are superb in reducing noise transmission.

9. White Noise Machine

These are small but unique devices that emulate sounds from nature. The ambient sounds promote a relaxing environment within the room, especially for people who have difficulty getting quality sleep.

PRO TIP: Seal door frames and windows by using weatherstripping or door sweeps. These will enhance wall soundproofing no matter how thin the wall is.

How can you soundproof walls of thin walls without people noticing?

Hang soundproofing materials that don’t require poking the walls. Acoustic sheets, moving thick blankets, acoustic curtains, and foam panels can be attached to the drywall using adhesive tapes and acoustic caulk.

PRO TIP: For better soundproofing, push heavy furniture flat against the wall. These pieces have high sound absorption quality as they are usually made of rich fabrics.

Pieces of furniture, like wardrobes and bookshelves, against your wall add mass and enhance sound. You can even place a soundproof blanket or foam panel between the furniture and the wall to further absorb any sound.

Does spray foam insulation reduce unwanted noise?

Yes. Though the primary purpose of spray foam insulation is for thermal rather than sound control, it is also effective in dissipating noise.

Do you want to block or eliminate sound, or do you want to control the echo?

If you are blocking noise or eliminating sound, you need drywalls with higher STC ratings. The higher the rating, the more effective the barrier to attenuating the sound.

On the other hand, if you want to control the echo, you need sound-absorbing materials to soak the sound and eliminate the echo effect.

PRO TIP: Attenuation in soundproofing walls refers to the process of reducing the force or impact of sound.


So now that you know how to fix thin walls, it will be easier for you to have a quieter room.

You may never have control of the external noise, but you can do away with loud noise by controlling what’s on the inside.

Choosing the correct sound-absorbing material for your project would be easier for you if you had considered all variables and factors.

Knowing the source of sound saves you time and money in getting all the resources you need. Thus, having thin walls will no longer be an issue.
