PREFORM specializes in acoustic solutions for offices. We take a holistic view of room acoustics and know that individual solutions are often required. That is why our certified sound absorbers for walls and ceilings are modularly expandable and available in special sizes. From mobile movable walls and partition walls, to ceiling and wall absorbers, to room-in-room systems, we have the right solution for every acoustic problem to improve room acoustics.
Open office landscapes and open-plan offices are in vogue. The new working environments stand for innovative strength and transparency of companies and are supposed to improve the communication of employees. Even though a lack of sound insulation in offices has long been criticized – you as an acoustician know that numerous mistakes are still made in the planning of open space offices and that sound can often spread unhindered.
We know that room acoustics in offices are not only about reverberation time. That’s why our sound absorbers for open-plan offices are optimized to reduce speech intelligibility.
Your project is a conference room and requires high speech intelligibility? With our sound absorbers for walls, ceilings and room-in-room, we develop customized acoustic solutions that measurably optimize room acoustics in any type of office space.
Hearing is subjective. That’s why your room acoustic analyses are so important. To achieve the target acoustics, you need sound absorbers that convince all along the line.
Our product portfolio includes forward-looking technologies for optimum sound insulation in the office.
Our patented sound masking system Presound creates a masking sound that effectively overlays the frequency range of human speech. This makes conversations unintelligible, which has a beneficial effect on the concentration and well-being of employees.
Presound is a suitable solution for improving room acoustics, especially in over-damped rooms and open-plan offices where speech intelligibility becomes a problem.
Our patented absorber material gypsum foam is the heart of our sound absorbers. Incoming sound waves are absorbed and slowed down in the gypsum foam before they can propagate in the room. The material, which is manufactured in-house, is unique in the industry and has excellent absorption properties.
Achieving the optimum reverberation time, speech intelligibility, sound absorption and sound insulation in the office in accordance with applicable regulations is a challenge. We know this and incorporate our know-how into our products. In your acoustic measurement or simulation, the calculated target acoustics are thus guaranteed to be achieved.
All our sound absorbers have been tested in the reverberation chamber according to ISO standards. On request, you can obtain the corresponding test certificates with the results for αs and αw. This provides security for your room acoustic calculations.
With our acoustically highly effective sound absorbers, the necessary measures can be implemented in accordance with authoritative
regulations, such as the workplace regulation ASR A3.7 Noise, VDI 2569 or DIN 18041.

“PREFORM convinced me by always finding individual solutions for my projects and not limiting me to standard sizes. At PREFORM, an internal acoustician is involved in product development. And for me, that is a clear advantage over other manufacturers. For example, I am an absolute fan of PREFORM’s Presound sound masking system. The system is revolutionary.”
