Is Egg Crate Soundproofing Effective?

In this blog, I will be explaining all about egg crate soundproofing, its qualities and its effectiveness as a soundproof material. Its applications, pros and cons and how recommended it is for soundproofing. All these questions will be answered in today’s blog. So, let’s get started!

What Is an Egg Crate Foam?

It’s a form of foam with egg crate-shaped sides. It works based on the decoupling phenomenon, which absorbs sound waves and reduces reverberation.

It also has a larger surface area than traditional flat-panel foam, which results in superior sound absorption.

Acoustic egg crate foam is often created from acoustic-grade polyurethane foam, but it can also be made from recycled paper and moulded pulp using a mechanised paper mache method, or clear plastic.

Because of its form, it reduces sound pressure building in a room. As a result, vocal clarity improves.

Applications of Egg Crate Foam

Below are some of the applications of egg crate foam:

Mattress toppers are used to improve the comfort of bed mattresses by allowing the foam to adhere to the contours of the body.

Sound treatment that uses the echo reduction approach and the decoupling phenomena, which is perfect for sound absorption and so soundproofing rooms like:

  • Studio
  • Home Cinema
  • Broadcasting Studios
  • Apartments

Sound absorption Vs Sound Blocking

Now, instead of using the terms Sound Blocking and Sound Absorption interchangeably as is common practice, let’s look at what they mean:

When vibrations from a sound source are absorbed by acoustical absorbent surfaces or elements, reverberation, echoing, and amplification is reduced.

The materials utilised for this function are usually porous and have a lot of air space to help them work better.

Sound blocking, also known as sound isolation, is the process of containing the sounds emitted by a source inside the confines of a predetermined area.

The materials utilised for this purpose are typically dense, thick, and heavy, with minimal porosity.

Sound Proofing’s Key Principles Soundproofing is the process of preventing sound waves from entering or exiting a room, resulting in acoustic isolation of the defined region.

Deflection

Sound waves can be deflected by using dense, non-porous materials in any building. This type of material is particularly effective at diverting or deflecting sounds that are transmitted via the air.

The extra bulk aids in the dissipation of soundwaves by producing a longer path and, as a result, higher energy is required for diffusion into any given space.

Blocking impact-borne transmission, on the other hand, is less successful. Airborne vibration has a higher power, pressure, and vibration class.

Absorption

Sound pressure waves are dispersed across a surface with interstitial spaces, preventing transmission through the vibration of solid molecules, a phenomenon known as absorption.

As a result, acoustic energy is absorbed. This type of material is typically used in open cavities where the depth of the material can be tolerated.

Furthermore, if the cavity were left empty, this type of material can prevent additional resonance, reverberation, and amplification of sound waves.

Absorption Are of Two Types:

  • Porous Absorbers
  • Resonant Absorber

Porous Absorber

Porous open-cell foams are excellent noise absorbers for a wide range of frequencies from medium to high. At lower frequencies, performance can be less outstanding. Several factors influence the absorption profile, including:

  • Tortuosity 
  • Porosity 
  • Material Density 
  • Material Thickness 
  • Cell Size 

Resonant Absorber

Helmholtz absorbers, also known as resonant absorbers, dampen sound waves while reflecting them. A resonant soundwave can only be absorbed throughout a low-medium frequency range.

Reflection

The method by which a soundwave is dispersed in space, or the comparative distribution of sound pressure fluctuations within a specific space. The sound is said to be adequately diffused when the sound pressure is evenly distributed across the room.

Diffusion

If a bothersome echo is caused by a specular reflection off a hard-flat surface, an acoustic diffuser can be added to the surface. It will disperse sound in every direction. This is a good way to get rid of noise pockets in a room. e is a substance that is applied to a surface. It will disperse sound in every direction. This is a good way to get rid of noise pockets in a room.

Decoupling

Decoupling is a technique for reducing the area of direct mechanical connection between the structure and the substrate. As an example, consider the walls and the materials used to finish them.

This action disrupts flanking transmissions, which normally travel through a structure’s stiffness and connection from beginning to end.

Damping

It is the process of using absorption, reflection, or diffusion to reduce resonance in an enclosed building. The overall sound level of the structure will be reduced through absorption, and the coherence will be reduced via redirection, rendering the undesirable sound harmless.

Distance

The greater the isolation or blockage from incident sound waves, the further distant an object or a location is from a sound-attenuating source.

This is because soundwaves lose energy as they travel through any medium, and are thus dampened over a finite distance via diffusion, reflection, and absorption.

Mass

By increasing the number of material molecules present, adding dense material for soundproofing can assist minimise transmission.

Soundwaves will have to waste more energy passing through dense materials, diminishing their impact on the space that requires soundproofing.

Pros and Cons

Some of the advantages of egg crate foam are as follows:

  • Very cost-effective 
  • Recommended for beginners 
  • Easy to install 
  • Widely accessible and in a range of styles for various uses.
  • Higher frequency sound absorption is better.

However, there are some disadvantages to using egg crate foam, including: 

  • It is not suitable for installation in large spaces 
  • It is not very good at absorbing noise unless used in conjunction with other soundproofing methods 
  • It must cover the entire area being soundproofed without any interstitial spacing
  • It is not very thick or dense, so it cannot effectively block sounds • It may or may not be fire-resistant

Is Egg Foam Recommended to Be Used for Soundproofing?

It all depends, as with most responses, on the user’s willingness to invest in soundproofing an area.

Compared to the much more expensive acoustic foam panels that provide sound absorption over low, mid, and high frequencies, egg crate foams give good sound absorption but primarily for higher frequencies.

Why Use Egg Cartons for Soundproofing?

That is an excellent question. Some acoustic foam panels are shaped like egg cartons. I’m sure that inspired someone to utilise egg cartons. They’re numerous, inexpensive (you already paid for and utilised the eggs), and offer the impression that you’re doing your part to help the environment.

And if the shape is the key deciding factor, it’s quite simple to presume they’ll work. Someone on a tight budget or with a strong desire to Minimize, Re-use, and Recycle could be forgiven for thinking that egg cartons can help soundproof a room or reduce ‘common wall’ noise.

I’ve seen paintings of them painted and placed in various designs on the walls. This allows you to change the style or colour of the walls without having to repaint them. Your wall, on the other hand, will most likely have glue spots (or locations where the glue has stripped the paint off), as well as numerous little holes from the push pins used to secure your egg cartons to the walls and/or ceilings.

Egg Crate Foam Vs Pyramid Foam

Soundproofing a Room with Egg Crate Foam

It can be used for a range of applications, including mattress toppers to improve comfort, packaging to preserve breakable products, and soundproofing to block out undesirable sounds.

Because of the cone design, egg-crate foam is a fantastic product to use for soundproofing. This is accomplished by its echo reduction mechanism, which is activated when noise hits the cones.
