Is Soundproof Foam Worth It? (Foam Box Test)

Soundproof foam is a porous, soft material that captures sound by converting it to heat through friction. This means that sound waves will be absorbed by soundproof foam panels rather than bouncing off painted walls or other flat surfaces.

While in situations where there’s too much noise to be blocked, you may not find soundproof foam to be the ideal fit, but for issues like echo and reverberation, soundproofing foam can be a pocket-friendly solution. 

It is scientifically proven that thicker material traps lower frequency waves because they are physically longer. Thus, the thickness of the foam helps in determining the frequency of sound that can be absorbed.

Higher frequencies will be absorbed by the thinner acoustical foam, whereas higher, middle, and lower frequencies will be absorbed by the thicker acoustical foam. The lowest of the low frequencies are absorbed by bass traps’ extra-thick construction. You, therefore, need to chalk out your soundproofing requirements first. 

Is Soundproof Foam Worth It?

Are you wondering whether soundproof foam is worth the investment or not?

Let’s examine the acoustic foam’s features in more detail to see if it is the ideal solution for your sound problems. 

Soundproofing foams can assist you to solve these issues and recording clearer audio. Many restaurants, worship places, workplaces, and educational institutions also struggle with excessive reverberation and echo.

  • Do diners at your restaurant express concern that it is too noisy for them to hold a conversation?
  • Is there a lot of echo and bustle in your workspace as a result of all the open areas and plain surfaces?
  • Is there too much resonance, making it difficult for the congregation to hear the priest speak?
  • Is it challenging to successfully teach inside the classroom because of excessive echo?

All of these issues can also be resolved using soundproofing foam!

Here, you can see for yourself how acoustic foam can help reduce sound. 

What Problems Will Be Solved By Acoustic Foam?

Different acoustic problems, such as echo, reverberation, and sound waves, can be resolved by using acoustic foam. If you are a Vlogger, an influencer, or a YouTuber, then these are common issues in a recording studio, podcast room, broadcast booth, game room, or anywhere else where you might be recording audio.

  • In your podcast, is there an echo?
  • Do your face the issue of echoing, jumbled sounds in your recordings?
  • Is there too much echo in video games, making it difficult to communicate?
  • Is it difficult to mix utilizing your monitors because your space has too much reverb?

The answer to all of the above questions is acoustic foam, you can use panels or tiles for improving the quality of sound in your studio.

What Problems Will Not Be Solved By Acoustic Foam?

While the uses of soundproofing foam are many, it may not be the best solution in the following scenarios: 

  • A room cannot be entirely soundproofed with acoustic foam. Many people believe that soundproofing a wall using acoustic foam will prevent sound from passing through.

    That is untrue! This misunderstanding is based on the reference to the acoustic foam wedges that are used in a lot of recording studios as “soundproofing foam” or “soundproofing panels” by various artists and people.
  • Noise from the outside won’t be stopped by acoustic foam inside!

    Many people who reside in large cities or close to train tracks or main roads attempt to cover a window or wall with acoustic foam in order to block out outside noise that keeps them awake at night. This is not how acoustic foam is intended to work!

Although applying foam to the ceiling or wall may assist a little, the noise will not be totally silenced.


What Are The Advantages of Using Soundproofing Foam?

Although soundproofing foam cannot give you 100% accuracy, it can certainly help you in reducing noise. Here are some of the advantages of using soundproofing foam.

  1. Improve Quality of Sound

Depending on the purpose, acoustic foam is cut into tiles with various profiles, including wedge, pyramid, egg, and square shapes. They function not just to absorb sounds but also to improve the volume and clarity of speech in a space. Acoustic foam, which simultaneously deals with sound of high and mid frequencies, can also be considered a low-cost heat-reduction facility that is used as bass traps in rooms’ corners or other locations where good sound mixes are required to reduce echoing sounds.

The fundamental idea behind acoustic foams is that they dampen sound waves by dispersing their energy as heat. The optimum air gap is necessary between the soundproofing panels and the walls to improve this effect. This increases the foam panels’ incident wave surface area, increasing the amount of absorption.

  1. Soundproofing through absorption

Sound waves can penetrate through the slightest of openings in walls, gaps, or other materials, just like light can. Due to the fact that acoustic foams eliminate echoes and background noise by absorbing it rather than by blocking it, they might lessen noise pollution and sound leakage.

  1. Enhance the design

Most people select soundproof foams for their music studios or work rooms in order to increase privacy and concentration while performing. Acoustic foam is available in a number of colors and textures, and you may choose to integrate the theme into the interior decor of your home. Some people decide to use a contour effect to accentuate the room’s sophistication and elegance.

Acoustic foams are available in a variety of sizes and thicknesses and can be mounted to doors, walls, ceilings, and other sections of a room.

  1. An affordable option
    Soundproof foam price is also comparatively less, thus making it a great choice. Check out this pack of 12 acoustic panels that are available on Amazon for just $12 a pack.  As compared to various other soundproofing solutions, there’s no doubt that acoustic panels are indeed easy on the pocket.
  2. Variety of Uses
    Soundproof foam is a multi-tasker! You can use it for your professional studios, podcasting, vocal booths, rehearsal rooms, and home studios.
  3. Easy installation
    The simple setting-up process of acoustic foam makes it fairly easy to install it in your room. To learn more, watch this DIY video on YouTube that will help you with a lot of installation FAQs.


If you are still wondering whether soundproofing foam is worth the investment, then the answer surely depends on your soundproofing requirements. Considering the level of sound you wish to block, you will need to determine the thickness of the acoustic foams, the coverage area, and their placements, as well. 


  1. What is the best kind of foam to block noise?
    The kind of foam you can use depends on the kind of sound you wish to block, however, you can try the following:
    1. Egg Crate Acoustic Foam
    2. Foamily Acoustic panels
    3. Mybecca Acoustic Foam Wedge

2. Will acoustic foam help in blocking sound?
Basically, it is the thickness of the foam that helps in determining the frequency of sound that can be absorbed. But keep in mind that while foam may absorb sound waves, complete blocking may not be possible.
