Room acoustics
Sense of space and reverberation time
Acoustics is a central aspect for a pleasant sense of space. If the reverberation time of spoken words or sounds is too long, you quickly feel uncomfortable. The causes of this unpleasant effect are generally hard and smooth surfaces that are not sufficiently sound absorbent. The reverberation time is regarded as the essential characteristic for the assessment of the acoustical quality of a room. It specifies the amount of time a sound level drops by 60 dB after the end of the sound. Speech intelligibility is another room acoustic parameter. In different rooms with the same reverberation time, speech intelligibility can also differ. Basically you can say: The shorter the reverberation time, the better the speech intelligibility.
Optimal solution – acoustic ceilings
Sound-absorbing materials must be used if reverberation times are to be optimized. The higher the sound absorption rate of a material, the more the reverberation time can be reduced.
Since the ceiling usually offers the largest free area of a room, an acoustic ceiling makes it possible to achieve the greatest reduction in reverberation times. If there is no possibility to install a full acoustic ceiling, ceiling panels and wall absorbers can also provide the required sound absorption.
Practical example – Ceiling refurbishment of a child-care center
With the new acoustic ceiling made of Fibro-Kustik boards, the reverberation times in some areas can be reduced by more than 50 %. Quote from an educator: “Relaxation for the ears”
The open-pore and sound-absorbing material of the Fibro-Kustik wood-wool acoustic boards, with mineral wool, is the ideal solution to improve reverberation times in rooms. The branching structure of the wood-wool boards and the underlying mineral wool literally swallow the sound waves.
Fibro-Kustik – The acoustic board
The Fibro-Kustik acoustic boards are manufactured with renewable raw materials from the region. Like the people, the landscape, and the weather, the boards also have their special characteristics: strong and robust, of course.
Due to their sound-absorbing wood-wool structure, Fibro-Kustik boards can be used to produce individually designed and highly effective acoustic ceilings, ceiling panels, wall absorbers, and room dividers.
The boards are available in four types: Florence, Barcelona, Paris, and Berlin. They differ in fire resistance and fiber widths.

Engineering and assembly
Whether for direct mounting, inlay mounting or concealed mounting - the Fibro-Kustik boards are available for different applications with different edge designs.
The boards can be mounted directly on substructures made of metal or wood, or with inlay mounting in a rail system.

Area of application
Wherever spatial acoustics are to be improved with creative aspiration, our Fibro-Kustik wood-wool acoustic boards come into play.
Schools and kindergartens
As our above-mentioned practical example of a child-care center ceiling refurbishment indicates, Fibro-Kustik boards are optimal for the reduction of disturbing reverberation times and thus for the improvement of room acoustics.

Sports facilities and recreational buildings
The sound-absorbing acoustic boards from Fibrolith can be used to produce wall and ceiling claddings which meet the required reverberation times in sports halls.
Product information
Catering
Fibro-Kustik boards with their distinctive wood-wool structure meet the current spirit of the times of interior architecture. In modern restaurants, cafes or bars, puristic and rustic products made from natural materials are in demand.
Product information
Offices and administrative buildings
Natural or colored wall and ceiling claddings in stairwells or freestanding room dividers with sound-absorbing Fibro-Kustik boards ensure good room acoustics in offices. Directly fastened or suspended acoustic panels optimize the reverberation times and improve the language comprehension.
Product information
Shops and sales areas
Here, Fibro-Kustik boards offer nearly unlimited possibilities of use. The double advantage: Acoustic boards firstly, with their natural and puristic surface-structure, which can be designed in any color, meet the spirit of the times of modern shop concepts. Secondly, in addition to the walls and ceilings, almost all surfaces in the sales room can be clad with the sound-absorbing boards.

Shooting ranges
Due to their excellent sound absorption values, Fibro-Kustik boards are particularly suitable for the sound insulation of sports and area shooting ranges. As far as safety is concerned, the boards have excellent rebound- and recoil-retardant properties. A corresponding expert report on the audit concerning the inhibitory sound recoil properties with Fibro-Kustik boards with respect to compliance with the shooting directive is available.
