Whatever your reason for soundproofing a room – whether it’s for privacy, better acoustics for a home cinema, a music study, or simply some peace and quiet – there are several options.

If you’re looking for a low-cost alternative to acoustical foam or other sound-absorbing materials, you may have heard that egg crates can be a good choice.

Egg cartons

However, egg cartons will only get you so far. As it’s a cheap DIY alternative to more expensive soundproofing options, you can’t expect incredible results.

In this article, we’ll outline why egg cartons probably aren’t the best soundproofing options and why so many people believe that they can keep noise at bay. 

So, can egg cartons really soundproof a room?

No. Unfortunately, egg cartons are not going to turn your room into a completely soundproof studio.

If that was the case, the expensive alternatives would be pointless. Theoretically, you could stick a bunch of egg cartons to your wall, but you’re not going to achieve optimal sound buffering.

They can certainly be used to help diffuse sound waves ever so slightly, as they spread them out and alter the way in which they move. However, they won’t block out much sound. 

The rumor that egg cartons work as soundproof wall padding probably came about because of their appearance.

After all, they do sort of resemble some of the soundproofing alternatives you can find online. The resemblance is actually pretty uncanny, but sadly, that’s where the similarities end. 

Acoustical foam for soundproofing in music studios is constructed of a material designed specifically to soundproof and scatter sound waves.

Those egg cartons were designed to cushion eggs and reduce vibration so they don’t crack and shatter before you get them home and safely store them in your fridge. Each of these has very different acoustical properties.

If you still insist on using egg crates to soundproof your room, you’ll need to do a few things to make it work.

Keep in mind that it will just minimize echo and won’t make any major difference, but it will not silence the noise. You can put them up as an extra precaution, but don’t expect them to magically stop all sounds from entering and exiting your room. It’s not designed for that.

Improving the Soundproofing Capability of Egg Cartons

With egg cartons, you can attain superior soundproofing effects. All you have to do is put in a little extra effort. The following are the things you should work on to improve the effectiveness of your egg cartons.

Improving the Soundproofing Capability of Egg Cartons
  • Do not rely solely on egg crates. Utilize old curtains or blankets from your home. If you’re soundproofing a wall, start by pinning soft items to it. The egg cartons should then be attached to the material.
  • Starch papers or other scrap fabric on one side of the cartons with adhesive. Use the filled-in side for soundproofing. Putting items on the containers will enhance the thickness and density of the crates. As previously stated, the sound will have difficulty penetrating dense materials.
  • You should also consider combining your egg cartons with other soundproofing techniques. If you’re wanting to soundproof your room, for example, look into different options. Determine the source of the noise and use better materials to soundproof it. Examine your doors and windows for air holes. Take your time sealing them. Investigate different noise-canceling techniques and put them to use.
  • Before affixing any container to your walls, make sure that it is completely clean. Remove any eggshells or dirt from the crate if you’re using old cartons. Remove all of the residues from the crate. If you’re using a foam or plastic crate, be sure it’s clean. However, cleaning soiled paper cartons is tough. As a result, if you have a dirty box, throw it away. It’s impossible to get rid of the stench of the filthy container.
  • Install pieces of cloth or foam within the apertures of egg cartons before hanging them on the walls to boost their soundproofing qualities. This will help to increase the density of the cartons as well as their ability to absorb sound.

What are some alternatives to egg cartons for soundproofing?

Soundproofing Blankets

Moving blankets, sometimes known as soundproofing blankets, are big insulated fabric pieces that mimic blankets. These blankets are used to insulate goods from moving, shaking, and thermal fluctuations.

Door Sealers

These do a great job of reducing noise from entering the space through cracks under doors or other unsealed areas in the room. They are used for both insulation and soundproofing purposes.

  • Mineral Wool

Mineral wool is a material that resembles tangled sheep wool. It is constructed of inorganic mineral elements. It is used for packaging, insulation, and soundproofing.

Acoustic Foam

Acoustic foam is a substance that has been scientifically developed to absorb and scatter soundwaves.

Both in shape and material design, it is efficient at soundproofing. It is lightweight and typically constructed of polyurethane foams and materials such as polyether or polyester.

Acoustic Panels

Acoustic panels are a simple and efficient choice for anyone who want to diffuse sound in a simple and appealing manner. These are huge padded panels that can be hung to help with noise reduction.

These are just a few examples of materials that can be used to lessen or completely eliminate soundwave noises.
