Room Mode 3D Acoustic Studio
Model low-frequency room eigenmodes in 3D, compare the same room against Hunecke, Sengpiel and Bob Golds assumptions, inspect source/listener coupling, then export reports, CSV, SVG, Helmholtz plan and JSON receipt.

WHY THIS IS DIFFERENT
From static room-mode calculators to a decision tool.
The classic calculators are useful for frequency lists, but this page adds a visual 3D squared-pressure board, explicit reference matching, source/listener coupling, cluster and isolation warnings, modal density bands, and exportable proof artifacts. It is built for home-studio owners, mix engineers, audio builders, and AI agents that need a verifiable acoustic planning receipt.
- Uses the rectangular-room mode formula with nx, ny, nz indices and selectable speed-of-sound assumptions.
- Explains why the same room can differ from Sengpiel, Bob Golds or Hunecke outputs because of 343 m/s, 1130 ft/s, temperature correction, or one-decimal dimension rounding.
- Separates axial, tangential, and oblique modes because their practical strength differs.
- Shows how source and listening position can excite, hide, or exaggerate the selected mode.
- Turns the selected problem frequency into a first-pass Helmholtz/perforated-panel sizing plan.
Boundary: Not a guaranteed acoustic treatment design, building plan, safety review, or substitute for room measurement.
