Acoustic Optimizer – EWA

More peace and quiet in Day-Care, Schools, Offices, etc ...

... in the Day-Care Center

In Day-Care Centers, the task of the Acoustic Optimizer is to reduce the everyday noise level. The sometimes unbearable noise, however, is generated by the room alone (not the children) and this is exactly what our Acoustic Optimizer solves. In addition, the intelligibility of speech, which is extremely important for children at this stage of development, is significantly improved by the EWA acoustic system.

... in Schools and Seminar Rooms

The focus in Schools und Seminar Rooms is on better speech intelligibility. Optimising this is the task of the EWA Acoustic Optimizer. The high noise frequency for hours on end stresses pupils and teachers alike. At the same time, it is significantly reduced by the Acoustic Optimizer.

... for Office and Conference Rooms

Even in Offices and small Meeting Rooms, noise reduction is a priority. Many speakers, many voices, a lot of unintelligibility and effort when talking. The Acoustic Optimizer prevents what is perceived as noise from coming from the corners and edges of the rooms right from the start.

Advantages of the Acoustic Optimizer EWA:

  • Highly effective: prevents the generation of distorted noise. 
  • No overdamping: speech intelligibility is significantly improved.
  • Space-saving: no loss of room height, walls remain free.
  • Cost-effective: no change to the lighting.
  • Sustainable: quickly installed - just as quickly removed (e.g. for rental properties).
  • Safe: the absorbent core is non-flammable (A1), the cover fabric is flame-retardant (B1).

While conventional acoustic solutions (e.g., acoustic ceilings) primarily combat reverberation and therefore muffle all sounds in the same way, our acoustic optimizer prevents annoying noises from occurring at the edges of the room. These noises impair speech intelligibility to a particularly high degree.
Our acoustic element creates a room where background noise is significantly reduced, where you can talk without getting tired, and where even those with hearing impairments can hear speech clearly, even from the back row. To develop this special acoustic element, we used physical findings from the fields of recording studios and event technology.

What our customers say:

Day-Care Bredow Estate

"If you know how terrible the gym used to sound, it's simply unbelievable."


Barbara Agricola, Youth Officer, on the gym at the Bredow-Siedlung Day-Care Centre

Day-Care Johannis in Werther

"The play sessions with the children have become more relaxed, as the children no longer have to shout over each other. ... When the children sing during music class, it is much quieter in the other rooms.

The communication and …

speech intelligibility during team meetings, which take place in the gym, have improved significantly."


Jasmin Kokaj, Director of the Johannis Day-Care Centre in Werther

Day-Care Bredow Estate

"The acoustic optimisers have also improved the acoustics in the stairwell. With six elements on the ceiling, the upper stairwell is much quieter than the one leading to the basement.’ ... This is a win-win situation for everyone, especially for the employees."


Jörg Havekost, Head of the Bredow-Siedlung Day-Care Centre in Wetzlar

Day-Care Bredow Estate

"We tested the Acoustic Optimizers in one room first. We chose the room where the morning catch-up group met. The effect was enormous. This was particularly noticeable when we changed the catch-up group room later."

"After the test, it was clear ...

... that we want to equip the entire day-care centre with the elements. To prepare for the decision, we were able to demonstrate the difference between a room equipped with the Acoustic Optimizers and a neighbouring room. That was convincing."

"What I also particularly like about the Acoustic Optimizers is that our wooden ceilings have been preserved. In contrast to other solutions discussed in advance, the low installation costs were also impressive in retrospect."
