How many sound absorbers do I need?
The recommended number of
sound absorbers per room depends on many factors. In addition to the size of the room, the noise sources in the room also play a role. The more sound sources there are in the room and the higher the noise level, the more
sound absorbers should be installed on walls and ceilings to improve the acoustics.
Calculate the required amount of sound absorbers
Use our
acoustic calculator to easily determine the
recommended amount of sound absorbers for your room. If you are unsure, take advantage of our

3. Our expert recommendation
Our recommended absorber coverage:
You can see how many sound absorbers are included in each pack and the area (m²) they cover directly in our product configurator.
As a rough rule of thumb: For mild reverberation/noise, covering ~ 10 % of the wall and ceiling surfaces with sound absorbers is often sufficient. For increased reverberation/noise, we recommend covering around ~ 20 %, and for strong reverberation/noise, up to ~ 30 % of the room surface area with acoustic treatment.
To noticeably reduce reverberation, a certain proportion of the room surface area, meaning the combined area of the walls, floor and ceiling, should be covered with sound absorbers. We recommend taking a gradual approach. In most cases, it also makes sense to start with the ceiling.
If you are unsure, start with a smaller amount of absorbers and add more as needed. This not only saves you money but also prevents excessive sound absorption, which can create an unpleasantly artificial acoustic environment.

Noise control in technical acoustics: How many sound absorbers?
Noise control in mechanical engineering or vehicle manufacturing always aims to reduce noise, meaning the greatest possible reduction in sound emissions. This requires targeted sound insulation. For example, this can be achieved by completely lining an engine compartment or a machine enclosure with absorbers of the greatest possible material thickness.
