A symbiosis of light and room acoustics
Acoustics and Light
We design and develop highly effective acoustic ele-
ments that absorb or scatter sound, creating a notice-
ably pleasant acoustic environment. This increases
concentration, promotes social exchange, and gener-
ates an overall sense of well-being. We produce the
acoustic elements from an innovative and high-quality
synthetic fleece made from recycled PET which is
precisely moulded into shape. This makes our lumi-
naires and acoustic elements a resource-efficient and
environmentally friendly choice in the long term. Be it a
new building or an acoustic retrofit, our room acoustics
experts will support you in optimising your building.
Based on your plans, we will carry out a standardised
calculation of the reverberation time and improve it in a
targeted manner using our acoustic solutions.
