Does Noise-Canceling Foam Work Both Ways? (Check Before Buying)

A quiet home is more like a dream nowadays.

All of us wish to be in a place where we are away from the world. It should be a space where you don’t hear the sounds barking, the kids rambling outside, and the loud music from the neighbors.

This dream can become a reality if you play by the right chords.

Installing the soundproofing foam is one solution that could help block unwanted noise.

How does the soundproofing foam function?

Acoustic foam for blocking sound from outside

Soundproofing foam is a robust material that can stop and absorb several acoustical energies.

Knowing how it works and whether it works from both sides will save you plenty of your time, money, and energy.

Even though there are different methods to soundproof a room, having access to a technique that works on dual sides is a solution to most of our woes.

When it comes to soundproofing, you should understand the structure of this material and the way it blocks the sounds. 

The sound-absorbing foam is softer and lightweight than its sound-blocking counterparts. Its flexible and open cell structure works as the natural sound wave absorber.

It prevents noises from reverberating at the hard surfaces like floors, walls, and ceilings.

It accomplishes this by converting sound energy into heat energy. This, in turn, reduces the ability of sound waves to bounce around the room.

The example of recording studios is excellent in this regard. The echo in these studios is reduced because they install acoustic foam and panels on the walls.

Does noise-canceling foam work both ways?

For the most part, the soundproofing foam works from double sides. However, it is most effective when the foam is evenly shaped on both sides.

The soundproofing material works quite effectively, but the foam’s shape matters too.

Flat surfaces create more chances for the sound waves to touch and bounce away from them. This probability of waves falling upon them is higher.

It falls at a particular angle on the foam since it travels in waves.

The absorption chances also increase because the material is absorbent.

In case you use reflective material, the chances of reflection are also higher.

Therefore, you should search for sound-blocking foam that is soft, flexible, porous, and contains many angles.

Simultaneously, if you are looking for a soundproofing foam that works on both sides, you should install these on the two sides of the panels.

So, the waves face the two directions with appropriate shapes and materials.

When to install the noise-canceling foam?

If the sound is penetrating through the walls and ceilings, you should find a way to block this noise.

If you want to block the sound, you should install the sound insulating foam within the wall construction.

These are dense, heavy panels that decouple the wall between rooms to stop the sounds from traveling across the materials.

Perks of using soundproofing foam

Acoustic panels for reducing noise at home

Typically, acoustic foam is installed to deal with noise pollution.

The foam is used to deal with reverberations sound makes, and it is different from the soundproofing capabilities offered by other strategies.

Some other benefits of using noise-canceling foam are:

Enhances sound quality

Noise-canceling foam is cut in tiles with wedge or pyramid shapes. It can also enhance the quality of sound in a room.

The foam deals with mid and high frequencies simultaneously.

Plus, you can count it as a cost-effective heat reduction facility placed in the corners of a room. Or you can choose the points where optimal sound blends are required as bass traps to minimize the echoes.

Ensure an ample air gap between foam panels and the walls so that acoustic foam can dissipate sound energy into heat.

It reveals a wide surface area of the foam panels for the waves to collide, thereby stretching the absorption surface.

Improves room design

Noise-canceling foam is made of open-cell polyethylene foam. Besides dealing with the noise, it also enhances the aesthetics of a room.

You can choose from a vast array of colors and textures that go with your room’s design.

For example, some people opt to apply contouring to bring sophistication to the room.

Acoustic foam is available in different densities and sizes. You can attach them to ceilings and doors so that it contrasts with the other features of your room.

When does the noise-canceling foam work both ways?

When you install the sound-blocking foam, make sure that it has the following features:

  • The foam should be soft
  • The foam should be porous
  • The foam should have multiple angles to absorb the sounds

Apart from confirming these properties, you should also install the foam on both sides, so it works both ways.

The panels should mirror each other and have the same shape.

Also, make sure that the panels face both directions to absorb noise coming from both sides.


Does soundproof foam keep the noise indoors?

Acoustic foam is soft and porous. It does not block the sound transmission and allows the sound to pass through.

Instead, it absorbs the sound and reduces echo in a room.

What shape of noise-canceling foam is the best?

Opting for large wedges can improve this shape’s overall sound absorption qualities. Its directional element can make it extremely useful for some users.

With its rounded end instead of a sharp point of the pyramid, acoustic foam is an affordable solution to your soundproofing needs.

Final Thoughts

Making a room 100% soundproof requires plenty of effort.

To ensure no sound problems in your room, you should provide enough foam on the walls and make it face inwards and outwards.

By cutting the incoming sound waves and their ability to echo off the walls, you can use the acoustic panels to soundproof your space entirely.

Being particular about the foam’s size and measurements are keys to maximizing complete noise reduction.

This will improve the overall sound quality in a room and cut the extra volume too.

The application of sound-canceling foam brings a significant difference in the acoustic properties of a room, be it a workplace, residence, or recording studio.
