How the room modes calculator works
Mode frequencies follow f = (c/2)√((nx/Lx)² + (ny/Ly)² + (nz/Lz)²). Modes are labelled axial (one axis), tangential (two axes), or oblique (three axes) for acoustic treatment planning.
Key terms
- Axial mode - energy along one room dimension (only one n > 0).
- Tangential mode - two dimensions involved; often clusters in small rooms.
- Oblique mode - all three dimensions; higher density at mid frequencies.
Frequently asked questions
- What is the difference from standing waves? Same physics; this tool labels mode type and sorts by frequency for treatment planning.
- Which modes matter most? Low axial modes below ~100–150 Hz often dominate bass unevenness in small rooms.
