Room modes calculator
List axial, tangential and oblique modes and identify dense frequency clusters.
Inputs
Result and recommendation
Enter values and run the calculation.
How to use it
Clusters do not automatically mean a problem, but they identify frequencies worth checking with measurements and listening tests.
Example
Example: a 4.2 × 3.4 × 2.6 m room with hard walls and partial panel coverage. Change one parameter at a time and compare saved variants.
Limitations
The result is a first-order model. Real reflections depend on geometry, furniture, gaps, mounting and the positions of the source and microphone.
FAQ
Does this replace a measurement?
No. It helps plan an initial variant and budget, but final decisions should be verified with an impulse-response measurement.
Are more panels always better?
No. One-sided absorption can leave bass problems unresolved and make the upper range too dry.
