Sound absorber

In many areas - whether in the office, kindergarten, school, meeting room - there is a significant increase in noise levels. This is due to modern architecture with highly reflective surfaces of floors, ceilings and walls. The result is high sound levels and poor speech intelligibility, which cause fatigue and impair performance. To reduce sound levels, we recommend that our customers install sound absorbers on the ceiling or in the upper wall area. Depending on the requirements for appearance or stability, various products can be considered as sound absorbers. For good room acoustics and a reduction in reverberation, partial cladding is usually sufficient. Approximately 30 - 50 % of the floor area of a room is recommended for this purpose, depending on the room height and the initial sound level. This measure significantly reduces the reverberation time and thus the sound level. This increases speech intelligibility, which makes a room much more pleasant for people.

How do sound absorbers work?


Sound absorbers are elements that "swallow" or absorb sound. In the process, the sound energy is converted into other forms of energy, such as heat or vibration energy.
The sound absorbers have a porous structure. This creates a flow resistance. This creates friction, which converts the penetrating sound energy into heat. This process is called absorption.

The sum of kinetic and potential energy now results in the available sound energy. The kinetic energy is strongest at the maximum sound velocity, so the sound absorbers should best be placed here. In this way, the absorbers develop the highest effect and ensure an effective reduction of the sound level in various rooms.
Especially open-cell acoustic foams or closed-cell foams with a special cell structure or even fibers of non-woven materials serve as efficient sound absorbers.

The sound absorption capacity of some materials is optimized by a special surface treatment, such as structure, embossing or lamination.
By installing ceiling or wall absorbers in a room, the sound reflection is reduced, the reverberation time is shortened and the audibility of the room is improved.
However, sound absorbers are also used in the technical field, e.g. in a soundproof enclosure.



Various sound absorbers


To improve the room acoustics in a room, you will find a wide range of different sound absorbers at soniflex. The sound absorbers should always be selected according to the respective rooms. While machines are enclosed with an enclosure, acoustic screens can stop the sound waves in waiting rooms or living rooms. Absorbers on the wall as well as under the ceiling also help to improve room acoustics.

We offer our customers the following sound absorbers:

Basotect / melamine foam sound absorbers

Basotect is the trade name for melamine foam. Sound absorbers made of this material are used in rooms where the sound level is to be reduced, the acoustics are to be improved and fire protection regulations are to be complied with. Especially in daycare centers, the office, school or call center, stairwells and living rooms, the material is highly recommended. In addition, thermal insulation can be achieved.

Sound absorbers made of polyester fleece


Sound absorbers made of this material are used especially in large offices, entrance halls or the waiting areas of medical practices.

Polyurethane sound absorbers

With this acoustic foam, you sustainably reduce sound and reverberation in small and, above all, large rooms.

Colored acoustic panels

Bring color into the rooms and significantly improve the acoustics in your rooms with these products. With modern acoustic pictures you also provide real highlights.

Inserts for grid ceilings

At soniflex, we offer you a large selection of different inlays for grid ceilings, which can be ideally used as acoustic elements for sound absorption. You can even get them in different colors.

Flame retardant

Fire protection should also never be forgotten when it comes to soundproofing. Our products are not only ideal for the acoustics in rooms and ensure that loud noise will soon be a thing of the past. The different solutions are also convincing when it comes to fire protection.
