Gabions and sound insulation: Impact on acoustic comfort

Gabions, structural elements made of metal mesh filled with stone or other material, are often found in engineering projects, but their impact on acoustic comfort in the environment can be surprisingly positive. In this article, we will explore how gabions can affect sound insulation and contribute to creating a quieter and more comfortable environment.

Acoustic Properties of Gabions

Gabions, combining a metal structure and filled material, have the ability to absorb and reflect sound. Materials used in the production of gabions can have different acoustic properties, which allows their use to optimize sound insulation in a specific environment.

On Picture No.1 we can see a few properties:

Penetration, Absorption, Reflection, Diffusion


Gabions have exceptional acoustic properties. Their ability to minimize sound penetration effectively reduces the penetration of sounds through their structure.

Gabions excel in absorbing sound and reflecting sound waves. Their construction enables effective control of the noise level in the given environment.

Gabions are able to effectively diffuse sound. This feature contributes to the even dispersion of sound and creates optimal acoustic conditions in a given space.

Sound Absorption

Sound absorption is one of the fundamental properties that make gabions with stone filling stand out. The stone material that forms their internal structure is not only a solid and durable element, but also creates microscopic pores and irregular surfaces. This characteristic is crucial for efficient absorption of sound waves.

The natural porosity and irregularities of the stone allow gabions to absorb and reduce sound in the surrounding environment. In practice, this means that gabions are ideal for places where it is necessary to achieve a lower noise level without creating an unwanted echo.

Gabions are also capable of acting as a physical barrier that encloses and dampens sound. Their weight and massive structure contribute to the blocking of sound waves and reduce the transmission of sound to neighboring areas.

On Picture No.2 we can see that their ability to absorb sound waves has a significant application in various areas, from public spaces, where it is important to minimize noise, to residential zones and office spaces, where acoustic comfort is a key factor for a comfortable environment. Thus, in modern construction and design, gabions play an important role not only in aspects of stability and aesthetics, but also in achieving an optimal sound environment.

They can even be an excellent acoustic element on highways, roads and other traffic routes. Their ability to absorb and reduce sound waves provides several advantages in the field of noise control in traffic corridors.


Picture No.3 shows that Gabions are also excellent for fencing your plot or garden. These constructions with stone filling have several properties that allow to effectively reduce the penetration and propagation of sound waves into the surroundings.

Their massive structure and porous stone material ensure the absorption and reflection of sound waves, thereby minimizing the transmission of sound to the surrounding areas, which not only serves as a functional solution for noise control, but also contributes to aesthetics.

On Picture No.4 we will compare what value in db (unit of measurement of sound intensity) can absorb the given fences, while we see that the gabion fence can absorb a value of 60 db. This value corresponds to a sound equivalent to normal traffic or office noise.

Gabions, in addition to their function in construction and landscape design, can significantly contribute to sound insulation and create a quieter and more pleasant environment. Their ability to absorb and dampen sound makes them a unique element not only in the field of construction, but also in the field of sound technology and urbanism. Due to their versatile use, the discussion about how effectively they can contribute to acoustic comfort is current and important.
