Wool felt as a natural
sound-absorbing material
Wool felt is not only aesthetic and durable, but also has excellent sound absorption properties, making it an ideal solution for many industrial and domestic applications. It perfectly combines functionality and sustainability, while effectively reducing noise and improving acoustic comfort.

Natural texture, effective sound absorption
The fibrous structure of natural wool, the raw material of which is wool felt, allows the material to effectively absorb sound waves. The unique structure of wool traps sound energy between the fibers, reducing echo and noise propagation. This property is particularly beneficial in indoor spaces such as offices, studios or residential areas where acoustic performance is key.
Multifunctional applicability
The versatility of wool felt allows it to be used in a wide range of applications. It also performs well as an acoustic panel, wall covering or insulation layer.

In office spaces
It helps reduce noise and improves the quality of the working environment.

In studios
Minimizes distracting echoes for clear and professional audio recordings.

In residential buildings
It reduces noise, creating a calmer, more relaxing environment.

Sustainable alternative to artificial materials
Wool felt also offers a sustainable solution for sound absorption. While many artificial materials – such as polyurethane foam or glass wool – can be harmful to the environment, wool is a renewable and natural material that decomposes naturally. This not only improves acoustic performance, but also contributes to reducing environmental impact.
Durable and long-lasting solution
Wool felt is not only effective, but also extremely durable. The durability of the material ensures that it retains its sound-absorbing properties for many years without compromising its structural integrity. In addition, its fire-resistant properties further enhance its safe use.
Stylish and practical
Wool felt is not only functional, but also aesthetically beneficial. Its soft, natural texture and wide range of colors allow it to match any interior style. This makes it an effective, visually appealing solution to addressing acoustic problems.
Sound absorption or sound insulation? What's the difference?
The two terms are often used synonymously, but they do not mean exactly the same thing. The main difference between sound absorption and sound insulation is that sound absorption affects the internal acoustics of a room (echo, noise level, reverberation), while sound insulation tries to block sound from entering from outside or outside.
Sound absorption, i.e. acoustic attenuation
The use of materials and solutions that absorb sound energy and thereby reduce sound reflection, such as the cave effect. The aim is to reduce the echoes in the room, thus achieving clearer speech intelligibility and better sound. Such materials include open-cell foams, felts, and acoustic panels.
Soundproofing
The purpose of soundproofing is to prevent sound from passing from one space to another, for example between adjacent rooms or between outside and inside. The important thing here is not to reduce the echo in the room, but to prevent sound from escaping through walls, doors or windows. Typical solutions include multi-layered walls, air-gap structures, heavy materials (such as layers of plasterboard, sound-absorbing foils).
What is the "cave effect"?
The cave effect occurs when sound travels for a long time in a room due to too many surfaces - usually hard or reflective - or due to the shape of the space. In this case, we may feel as if we are talking in a cave, the sound is prolonged and speech becomes difficult to understand. This often occurs in large, empty, hard-surfaced rooms, such as churches, sports halls, offices, hangars, but it can also occur in smaller rooms if there is not enough acoustic attenuation. To reduce the cave effect, sound-absorbing elements, such as acoustic panels, felt materials, curtains, carpets, textile coverings, are used to shorten the echo and create a more balanced, clearer acoustic environment.
