Materials and textiles – how do they affect acoustics?

Today, noise pollution has become a critical issue, and there is virtually no household unaffected by it. Even in the rare case where there are no running appliances—such as a refrigerator or electronic devices generating background hum—external noise still finds a way to seep in.

Even with proper insulation, outdoor sounds from traffic, neighbors, or urban activity often penetrate living spaces, disrupting comfort and tranquility.

What Do Textiles Have to Do with Noise?

At first glance, it might seem like materials and textiles have little to do with noise pollution. But this is merely an illusion.

It’s no coincidence that theatres and concert halls—professional, acoustically engineered environments—place great emphasis on the use of specialized textiles to achieve ideal sound conditions. So why shouldn’t sound absorption play just as important a role in our homes?

When used properly, acoustic fabrics can make a significant contribution to restful sleep, reduced stress, and better relaxation—all essential elements of a higher quality of life.

What’s wrong with noisy spaces?

What? Basically everything. In a room with a booming, banging space, concentration is particularly difficult. What’s more, premature fatigue is inevitable. Many personal spaces have these characteristics, even if few people have been aware of them until now. Poor acoustics is a fact that should not be accepted, because although you obviously cannot turn the room inside out, the textile industry’s pearls can help a lot to create a better sound. Surfaces that improve acoustics cannot be exclusively acoustic panels. Even furniture, soundproof carpets, acoustic curtains, sofas, armchairs can make a significant difference to the acoustics of a room. But also pay attention to the corners of the room. In corners you can put several types of bass traps or corner elements covered with textiles of varying materials.

Why is this so interesting?

Because corners are usually the most problematic from an acoustic point of view.

Now, back to textiles, because these surfaces can also perform their function because they have the right covering. In general, textiles provide what is known as porous sound absorption, but also high-frequency sound absorption. Obviously the internal structure of the materials has a major influence on the effectiveness of sound absorption. An excellent example of this is flax. The structure of flax, i.e. its fibres, forces the sound waves to change direction continuously. This is a good thing because it takes a relatively long time for the fibres to eventually pass through the material. Each change of direction results in a loss of energy. Add to this the bonus of the presence of the wall, which can bounce the sound waves back into the fibres, and the process is doubly successful. By the way, this is the principle of passive sound absorption in very simple terms.

What makes a material a good acoustic material?

To get a little closer to what makes a textile ideal for sound absorption, here is a definition that is quite easy to digest for the layman. The acoustic porosity of a textile is the better the greater the number of voids in the material, the denser and thicker it is, and the greater the ratio of the total volume of the material. It is no wonder that many people prefer, for example, polyurethane acoustic foam or acoustic rockwool, from which the aforementioned panels are made. Textile fibres or wool felts are also often used.

Can acoustic properties be shaped afterwards?

Yes. That’s the good news! In fact, most built spaces do not boast much to boast about in this area. The insertion of a single drapery in most cases, or a larger surface area for armchairs and sofas, or perhaps a brain mat for the walls, can help enormously in reducing noise pollution and balancing acoustics. Alternatively, the use of acoustic panels, as mentioned above, is also an excellent and effective idea.

In other words, maximum success can be achieved with a minimum investment of time and money. And not just in the home. The working environment is also very important to embody optimal characteristics. Otherwise, focus can become difficult, attention can be impeded and productivity can be reduced, which is not a very positive outcome, to say the least. Especially as all this can be easily prevented, thus raising productivity at work to a higher level. It’s easy to see that this is actually a smart investment that can improve companies’ revenues and employee satisfaction.

The real beauty of using textiles for sound absorption is that it’s not just a smart acoustic strategy—it’s also a stylish design choice.

After all, who could deny the aesthetic appeal and versatility of textiles in terms of color, texture, and pattern? Likely no one.

By incorporating these materials, your living spaces are enhanced with elements that appear purely decorative at first glance—but in reality, they serve a much deeper purpose: creating a calmer, more comfortable home environment.

And that is a value that should matter to everyone.
