Room Mode Calculator
Enter your room's length, width, and height to find every standing wave your room produces below 300 Hz — the range where small-room bass problems live.
- 01
Enter Dimensions
Your room's real length, width, and height — meters or feet.
- 02
Calculate Modes
Every axial, tangential, and oblique mode up to 300 Hz, computed instantly.
- 03
Inspect Frequencies
Clustering and gap detection show where your room's bass problems actually sit.
Continue planning your studio
Room modes depend only on the size of the room. Next, see where the speakers and listening position sit in it, then how much treatment to start with. Want to enter the room once and carry it through placement, RT60 and a treatment plan in one editable file? The Studio Acoustic Toolkit includes a Studio Project Workbook for that, with a measurement guide and a setup checklist.
Or ask for a human review of your room.
From room modes to a studio plan
A room mode calculator predicts resonances from room dimensions. It does not measure the response at your chair. Start with speaker and listener placement, then test treatment choices with measurements in your actual room.
