Room Acoustics 2D: Standing Wave Heatmap
A Canvas2D plan-view of a rectangular room: pick an axial or tangential mode, adjust dimensions, absorption and speed of sound, then place a source and listener to read the standing-wave SPL between them.
This 2D companion draws the same room-mode physics as the 3D version — f = nc/(2L) for axial modes, f = (c/2)√((nx/W)² + (ny/D)²) for tangential ones — as a plain Canvas2D SPL heatmap instead of a WebGL shader. Pick a mode, resize the room, and click to place a source and listener; the RT60 (Sabine) and Schroeder-frequency read-outs update live as you change absorption and room size.
Canvas2D plan-view SPL heatmap of a rectangular room's standing-wave pressure field, with axial/tangential mode selection, absorption and speed-of-sound controls, and live RT60/Schroeder readouts.
