Frequently asked questions
What exactly does the calculator calculate?
It calculates axial spatial modes along the three main axes of length, width and height.
Why are axial modes important?
They are often among the strongest deep resonances in the room and help to classify typical bass problems.
Are tangential or oblique modes included?
No. The first version deliberately focuses on the axial modes as the most important introduction.
Why is the temperature selectable?
The speed of sound changes slightly with temperature. This also causes the calculated modes to shift slightly.
Does the computer replace an acoustic measurement?
No. It helps with orientation, but does not replace measurements with a microphone and suitable software.

Rule status and context
- Formula
- fn = n x c / (2 x d) for axial modes of a spatial axis
- Note
- Only axial modes are calculated based on the entered spatial dimensions.
