The Best Noise Barrier: Our Choices

Noise barriers: Buying and evaluation criteria

We will then show you which criteria you should use to choose the right model from a wide range of sound barriers. When buying a soundproof wall, you should pay particular attention to the following points:

In the following paragraphs we will explain the individual criteria in more detail.


An essential purchase criterion for sound barriers is the place of use. Basically, a distinction is made between sound barriers for indoors and sound barriers for outdoors.

In the following, we will go into more detail about the two types.

Noise barriers for indoors

There are sound barriers that are intended exclusively for indoor use. They can be installed directly in the room, which can be advantageous in flats as well as in offices. The wall also contributes to privacy.

Soundproof walls for indoors are available in a wide variety of materials and thicknesses. Depending on your personal needs, there are various models that may be suitable for you.

Noise barrier for outdoors

An outdoor sound barrier is particularly suitable for people who want to keep quiet in their garden. Another positive effect of a soundproof wall in the garden is that it also serves as a privacy screen and thus protects your privacy.

Here too, sound barriers are available in a wide variety of designs. Your decision should be based primarily on your personal needs.


Another important point that you should take a closer look at before you buy is the material of the soundproof wall. Here, too, a distinction is made depending on the place of use.

Only sound barriers made of fabric are suitable for indoor use, while there are more alternatives for outdoor use. The respective materials will now be discussed in more detail:

  • Fabric
    Sound barriers made of fabric are only suitable for indoor use. They would be unsuitable for outdoor use due to various factors, primarily weather resistance.
    However, they are perfectly suitable for indoor use. They are available in various thicknesses, heights and lengths.
  • Wood
    Wooden sound barriers are the most popular for the garden. Not only are they particularly easy to install, they are also one of the more cost-effective options. In addition to providing sound insulation, they are also very suitable as privacy screens in the garden.
  • Concrete
    There are also concrete sound barriers for your garden. These are considerably more expensive, but also much more robust than wooden noise barriers. Concrete walls also tend to look more elegant and are particularly popular for new houses.
  • Coconut fibre
    If you prefer a very green and natural garden, you can opt for a soundproof wall made of coconut fibres. This has the characteristic that it forms an ideal base for a wide variety of climbing plants. It is also easy to assemble, which is reflected in the price.

Sound insulation class

Before you buy, you should also find out about the sound insulation class of your soundproof wall. This provides you with information about how well your wall protects against sound and in which decibel range you are located.

The sound insulation classes for walls are sorted alphabetically. In Germany, a distinction is made between the classes A* to F. A* stands for the best sound insulation. Where A* stands for the best sound insulation and F for the worst.

To give you a feeling for this, you can imagine it like this: With a sound insulation wall of class A*, loud music from the neighbour is barely audible, whereas with a sound insulation wall of class F, even the normal conversation of the neighbours can still be clearly heard. In the lowest class, therefore, there is practically no sound insulation.

Noise barriers: Frequently asked questions and answers

In the following section, we would like to answer the most important questions about noise barriers. We have selected the questions for you and answered them shortly.
After you have read through the guide, you will be well informed about noise barriers.

What is a noise barrier?

A sound barrier can also be called a noise barrier and describes a wall that serves as a sound barrier. It is most often used in gardens to keep out noise from adjacent neighbours. However, such a purchase can also be useful if a house is located on a frequently used road.

As already mentioned above, sound barriers are divided into different sound insulation classes from A* to F. You should find out about these before you buy. You should always find out exactly what these classes are before you buy, because they indicate how well a soundproof wall actually repels sound.

What types of noise barriers are there?

Basically, a distinction is made between noise barriers for indoor and outdoor use. Within the two types, however, there are different designs, which we will discuss in more detail below.

Noise barrier for indoor use

A sound insulation wall for indoor use is particularly suitable for offices or to create a little more privacy in one's own flat, especially in the case of a shared flat.

Soundproof walls for indoor use are always made of fabric, whereby there are different models in terms of thickness, height and length.

In the meantime, there are also multifunctional soundproof walls for the interior, which are equipped with a pinboard-like fabric, for example. However, it must also be said here that these are then correspondingly more expensive, but worth considering especially for entrepreneurs.

If you are also thinking of setting up your own home studio, there are also various models of soundproof walls that are ideal for such work.

Soundproof walls for outdoor use

In the outdoor area, the sound insulation wall is always used in the garden. Here, a distinction is essentially made between three different materials. We have listed the respective advantages and disadvantages of these products in the following overview:

Type Advantages Disadvantages
Wood easy to assemble, good sound insulation, inexpensive not very weather-resistant, not very stable
Concrete weather-resistant, very good soundproofing, modern design expensive, time-consuming assembly
Coconut fibres simple installation, substrate for climbing plants, good sound insulation expensive, not very weather-resistant

It is best to make your purchase decision here first and foremost against the background of your personal needs.

What does a sound barrier cost?

As already mentioned, sound barriers are essentially made of four different materials. The price already varies greatly depending on the material used. To give you a better overview, we have compared the prices in the following overview:

Type Price per metre
Fabric from 60€ / metre
Wood from 70€ / meter
Concrete from 90€ / meter
Coconut fibres from 90€ / metre

It should also be mentioned at this point that the prices can also vary greatly from those listed above, as the individual products also differ in terms of their sound insulation class, the manufacturer, as well as the thickness, length and height of the sound barrier.

What are the alternatives to a noise barrier?

Unfortunately, there are no real alternatives to a soundproof wall. If your house or flat is not equipped with special, integrated sound insulation from the start, you will not achieve the desired sound insulation without a sound barrier.

There is no real alternative to a soundproof wall, but these are available in a wide variety of designs, so there should be something for everyone.

This is particularly difficult outdoors, i.e. in the garden. Here there is no alternative to a soundproof wall. If you want more peace and quiet in your own garden and want to suppress the noise of your neighbours, then you will not be able to avoid a soundproof wall.

The good news is that noise barriers are now available in a wide variety of designs, so there is something for everyone.

Can I build a noise barrier myself?

In principle, it is possible to build a noise barrier yourself. It should be mentioned at this point, however, that this requires a certain amount of intuition and craftsmanship. In addition, you need to have the appropriate knowledge to ensure that the soundproof wall really fulfils its purpose and deflects the sound accordingly.

For hobby craftsmen, this is certainly an exciting project, but in really urgent cases and for general beginners, we would rather advise you to buy. This way you can be sure that the soundproof wall will do exactly what it is supposed to do.

How high should my noise barrier be?

The appropriate height of sound barriers depends on the sound level to be reduced. In general, however, the stronger the noise, the higher the sound barrier.

However, it should be pointed out that this is only a rule of thumb. The actual height required depends on various factors, such as the material, the thickness, the length and the sound insulation class of the wall. Basically, you should already be able to estimate the necessary height of your sound insulation wall on the basis of the sound insulation class

If this is not the case, we advise you to consult a specialist and, if necessary, ask again before you buy the wrong product.


A soundproof wall offers you perfect protection against noise. You can use soundproof walls for a wide variety of purposes, such as in your home or office, or even in the garden to create a little more privacy. In addition to sound insulation, they are also perfect as privacy screens for outdoor use.

Sound barriers are now available in a wide variety of materials, and your decision should be based on your personal needs. The range is now so large that there is something for everyone.
