Sound Absorption Materials

At Soundproof Cow, reducing background noise is what our sound-absorbing materials are meant to do — no matter if the sound is coming from outside, or if you’re the one who’s making it. We have a long list of noise-absorbing materials that include acoustic panels, studio foam and more.

Communication is important, and we strive to help you create a setting with the least amount of disruptive background noise, improving speech intelligibility and the overall listening environment. Soundproof Cow is unique because we not only have the best sound absorption materials available, but we also do soundproofing with style. For example, we offer completely customizable art acoustic panels that add substance, style and sound absorption to any wall.

We offer the best sound-absorbing materials you can find for use in your home, office, workshop, studio or any area where you want exceptional sound quality. Before we get started, it helps to understand how sound and sound absorption works.

How Does Sound Work?

Sound waves are created by vibrations. For example, when someone sings, their vocal cords vibrate and send waves through the air to the listener. Higher frequency sounds consist of short sound waves, whereas lower frequency sounds contain long waves. Higher frequency sounds don’t bend as much around barriers and are reflected by thin materials. Lower sound waves pass through thinner materials. In general, sound loses energy as it passes through walls.

Noise is unwanted sound and happens when sound is not absorbed by anything and reflects off of walls or other materials. This is why sound-absorbing materials can come in handy. You can check out and compare the noise reduction coefficient (NRC) for each of our products to get an idea of how well each material absorbs sound. The higher the NRC, the more sound a product absorbs.

How Do Sound Absorption Materials Work

Sound waves will do one of two things when they encounter an object – they can be absorbed, or they can be reflected. When sound is reflected, it is sent back into the room. When it’s absorbed by a sound-absorbing material, it turns into a small amount of heat energy. Acoustics science involves finding the right balance between absorption and reflection.

sound waves can be absorbed or reflected

Imagine you’re watching a band play in an auditorium. If the entire space were covered with sound-absorbing materials, the walls would absorb too much sound and make the music sound flat. The musicians would also have to work hard not to make any mistakes. However, some reverberation would help the music ring beautifully, as long as there’s not too much echo.

There’s also the matter of sound transmission from one room to another. Just like sound absorption, certain materials are better at blocking sound than others. Controlling sound between rooms is sometimes referred to as sound insulation.

What Are the Best Sound Absorption Materials?

Sound absorbing materials are meant to improve the quality of sound within a room by controlling sound reflections. The desired effect is to reduce unwanted noise like echoes or high-pitched laughing. Sound-absorbing materials can help musicians find greater satisfaction with their music, or help students stay focused when they’re studying in the library. Sound absorption is useful in many different commercial and residential settings.

How do you know which material is best? Let us help you decide. We put together a quick, convenient list of our best sound-absorbing materials, so you can learn more and choose the perfect material for your soundproofing needs.

What to Consider When Choosing Sound Absorption Materials

We offer many different noise-absorbing materials, and they are all beneficial and versatile. So, how do you know which one to choose? Consider the following factors to help you narrow your options:

  • Where you are soundproofing: The first thing you need to consider is where you plan to soundproof. For example, do you want to soundproof in the bedroom? If so, you might choose acoustic panels in a soothing color. Do you want to soundproof a workout area where sweat and moisture can fly? You might be better off with a water-resistant panel.
  • What are you trying to soundproof: Next – what exactly are you trying to soundproof? If you wish to soundproof an air conditioner, then you want to buy a material you can customize to fit into the unit. If you want to soundproof an entire room, then choose a material you can install on the walls that meet your sound-absorbing needs and your budget.
  • What are your needs: Do you want to absorb sound or reflect it? Different products are designed to provide different solutions, so it’s important to talk to an expert and figure out your exact soundproofing needs.
  • What look do you want: Are you going for a natural, environmentally-friendly look in your garage or workroom? You can choose a recycled material. Want custom art in addition to sound absorption? You definitely have options with Soundproof Cow.
