Room Mode Calculator

Axial · Tangential · Oblique Mode Analysis

How to use this calculator

1. Enter room dimensions — Input your room's Length, Width, and Height in feet or meters. Toggle units with the buttons above the inputs.

2. Set your frequency range — Default is 20–200 Hz (the problematic bass range). Adjust if you're looking at higher frequencies.

3. Read the results — The calculator shows all room modes in your range, color-coded by type:

🔴 Axial (strongest) — between two parallel walls. These cause the most audible problems.
🟡 Tangential (moderate) — between four surfaces. Less energy but still noticeable.
🔵 Oblique (weakest) — between all six surfaces. Minimal impact.

4. Use the hover tones — Hover over any mode frequency to hear what it sounds like. This helps you identify which modes are actually audible in your room.

5. Interpret the results — A cluster of modes near the same frequency means trouble. Widely spaced modes (good distribution) means a cleaner-sounding room. Tip: aim for no more than 3 modes within 5 Hz of each other.
