Quick and simple planning of comfortable room acoustics
The Knauf Ceiling Solutions Acoustics Calculator helps you create a comfortable and safe room experience. Acoustic planning is based on internationally approved standards such as DIN 18041, BB93, or NF S 31-080. By using multiple parameters, you can easily define the use, type, geometry, and furnishing of the room, providing a perfect basis for designing suitable ceiling and wall solutions.
Frequently Asked Questions
What can be calculated with the acoustic calculator?
According to the simplified calculation method (Sabine's formula T=0.163*V/A), the basic parameters of the room acoustics can be calculated. Depending on the application and room use, this usually includes the reverberation time, built-in equivalent absorption surface or sound level reduction.
Which standards does the calculator include?
-
DIN 18041 (March 2016)
-
ÖNORM B 8115-3 (July 2023)
-
Building Bulletin 93 (December 2014)
-
Arrêté du 25 avril 2003 (Établissement d'enseignement et de santé)
-
NF S 31-080 (January 2006)
For which room types can I make an acoustic calculation?
The calculator provides all room types that are included in the respective standards (e.g. classrooms, open-plan offices, intensive care units, etc.).
Which room geometries can be defined?
You define the room geometry individually by entering the length, width and height for square and L-shaped rooms. It is also possible to design any floor plan with a constant height.
Can a room interior also be defined?
Yes, in addition to the selection of predefined raw ceilings and floors, it is also possible to add floor coverings, walls, windows, doors, and furniture to the design. Every additional surface influences the overall acoustic effect of a room and serves as a reference for the selection of suitable ceiling and wall absorbers.
Is it possible to integrate both ceiling and wall absorbers into the planning?
Yes, each surface (walls, ceiling, floor) can be individually assigned and, if necessary, further subdivided and covered with different materials.
What ceiling and wall absorbers are available?
