Building or renovating a new space can be an incredibly exciting prospect. But it can also be quite daunting. One of the many choices you’ll have to make is what kind of materials to use for soundproofing. Cardboard is a cheap and easy option, but is it worth your time and effort?

According to the report of Wikipedia, Cardboard soundproofing has a Noise Reduction Coefficient of 0.05-0.15 for high frequencies and 0.04-0.09 for low frequencies.

That means that a wall made of cardboard will reduce low-frequency noise by only 20% to 50%.

Cardboard is an old, but still effective solution. It is widely used in soundproofing studios and stages. However, it can be rather tricky to use it for interior walls because they need to be held vertically so there’s no way the flimsy material could support itself.

That’s why should you use it as the best soundproofing material or not? Is it worth your time and energy? Is there are some other soundproofing materials? That’s why you need to read this article.

What Is Cardboard Soundproofing & How Does It Work

There are a lot of myths about No products found. soundproofing. Actually, sound effects every material from which a wall is made. 

In this case, the wall will attenuate or amplify certain frequencies. For example, if you want to build a home theater and need to make it feel as if the actors were right there with you, you’ll have to use special panels that will absorb low frequencies.

If, on the other hand, you want to keep sound from leaving your property, you might want to consider using specialized materials that will reflect high frequencies. 

Cardboard is basically a big piece of paper with flaps. It’s not built for durability or stability.

However, if you use it correctly and reinforce its structure with some extra materials like No products found.. You might just have the perfect solution for your soundproofing needs.

Some Cardboard Soundproofing Projects

If you’re playing drums or recording vocals, this can be incredibly frustrating. They turned to Cardboard Acoustic Panels to solve their problems. 

2. Soundproof Cardboard Box (School Project)

Soundproofing cardboard box is a popular middle and high school project. Usually, students use this material to soundproof other things. So that they can achieve the optimal sound quality.

This is a great project if you like to learn about the basics of acoustics and soundproofing materials. While there are a few variations to the design, this is basically what you’ll need: a big cardboard box, some egg cartons, and a hot glue gun.

Students use egg cartons because they’re light but very good at absorbing sound waves. You might not think of it when building or decorating your home but simply adding some egg cartons inside the cardboard box will improve the acoustics.

3. Cardboard Soundproof Room

Tips For DIY Cardboard Soundproofing Projects

Here are some tips for the DIY Cardboard Soundproofing Projects you need to consider:

  • Choose Thickness Wisely: This is not the place to save money. If you go with thinner cardboard, you aren’t going to get as much sound reduction as thicker cardboard will provide. Thicker = Better
  • Use Hot Glue: Glue is an underrated tool in home renovations and if used correctly, it can have a very big impact on how well your project works. For example, if you’re trying to make acoustic panels and want the best results, use hot glue. It’s not expensive and it will hold your cardboard together like nothing else.

How To Install Soundproof Cardboard In Your Home

Here is the step-by-step process to install soundproof cardboard in your house. Follow the step and you will get the best results.

Step 1st: Measure And Cut Your Cardboard Pieces

The first thing you need to do is measure and cut your cardboard pieces. If you’re trying to soundproof a room, use egg cartons as the primary sound insulator.

They consist of thousands of little foam cells that absorb sound waves very well. You can easily glue them to the walls and ceiling with hot glue.

Step 2nd: Apply Damping Material

Do you know what a sound wave is? A sound wave is basically a pressure that moves from one point to another through the air or some other medium.

The speed of this movement depends on several factors like the type of material, its stiffness, density, etc. 

In drywall, sound waves move easily through the tiny gaps between the panels. In order to prevent this from happening, you need to apply some damping material that will fill up those spaces and make them more rigid.

Step 3rd: Glue Your Pieces Together

This may not be as simple as it seems. While a glue gun is a good option, hot-gluing your pieces together will have a much better effect on soundproofing.

Step 4th: Add Egg Cartons Or Foam

This is where egg cartons come in handy as you can glue them to cardboard panels or any other type of building material for that matter. They are not expensive and they’re easy to install – just peel off the paper, apply glue to your desired spot, and stick them in place.

Step 5th: Apply An Acoustic Sealant Over The Egg Cartons

This will keep the sound waves from passing through any seams between different pieces of cardboard and egg cartons. Better yet, you can use acoustic foam for this purpose too.

Step 6th: Paint Over The Cardboard Panels

Painting over the panels will make them look nice and also cover up any seams that may decrease the soundproofing effect.

Step 7th: Apply Two Coats Of Paint

Don’t be cheap, use two coats to cover up any traces of the seams because once the tape loses its stickiness, there’s not much you can do about it.

Step 8th: Add Hooks To Hang Curtains

If you want to make your cardboard room functional too, why not install hooks to hang curtains? That way, you can either close the curtain or remove it completely if needed.

Step 9th: Install A Door Seal To Soundproof The Entrance

If you’re trying to soundproof a room, don’t forget the door! Installing an entrance seal will make sure that any sound waves that may get in won’t be able to enter freely.

This may sound complicated but you can easily do this in your own garage or backyard if you have a bit of spare time and a desire to learn. Compared to other types of soundproof building materials, cardboard is relatively cheap and easy to use.

Downsides Of Cardboard Soundproofing

  • Inconvenient: It is inconvenient to assemble your boxes. You have to cut them into the right size then glue them together with a hot-glue gun or tape.
  • Noise Reduction: It may not provide the noise reduction you are looking for. The Egg Carton method will reduce some noise. But
  • Porous: It is porous so it will allow some noise in, especially when the weather changes. Some of this noise may come through your heating system or chimney.
  • Sound Absorption: Cardboard is not a highly absorbent material. While egg cartons and acoustic foam can make it slightly better, you should really consider alternative soundproofing materials if you want to do the job right.
  • Environmental: Your cardboard panels may be harmful to the environment as they may contain toxic chemicals used in their production.

Other Soundproofing Materials

Here are some other soundproofing materials you can use in your house. These materials also can replace the cardboard.

1. Soundproof Panels

Soundproof panels are the traditional choice for home soundproofing. They are very similar to drywall, except they have a specially designed core which gives them their high noise reduction qualities.

While not suitable for DIY projects, you can find many ready-made acoustic panel systems online or at your local hardware store.

2. Acoustic Curtains

If you choose uPVC windows in your house, it is better to use acoustic curtains as the soundproof material on them. This will give you maximum noise reduction and also allow some light through while keeping your privacy protected. 

3. Soundproof Tiles

Soundproof tiles are a sound-absorbing material commonly used in the home. They are available as adhesive panels or can be tiled directly onto your room’s walls or ceiling.

You can use them independently to cover up any sound leaks or apply them over other soundproofing materials like acoustic curtains and insulation for maximum noise reduction.

4. Soundproof Blanket 

Soundproof blanket is the sound blocking sheet. That is made of acoustically transparent fabric. The absorption performance can reach NRC 0.85 in the frequency range of 500 to 4000 Hz, even more than 700Hz.

It can be used for all kinds of doors, including the sliding door and so on. At the same time, it has excellent airtightness performance.

5. Foam Sheets 

It is the common soundproof material for windows. It can be used directly to cover up windows or doors, especially when you don’t want to remove them permanently or just need a temporary solution.

You can also find some foam sheets with high noise reduction quality that are specially designed for this purpose.
