3D Room Mode Explorer
See boom and null zones for each standing wave — then drop a desk on the map and listen at that seat.

Shoebox modes
This explorer uses closed-form Rayleigh modes for a rectangular room. Real rooms with furniture, doors, and angled walls need a full eigen solve — that is what the product BEM / voxel solvers do.
Frequently asked questions
- Why does the pressure heatmap show hot and cold spots?
- Each room mode is a standing wave with pressure maxima at walls/corners and minima (nulls) at specific interior points. The heatmap sums every mode below 250 Hz, so a desk sitting in a null for one mode can still be in a peak for another.
- Does this explorer account for furniture, doors, or angled walls?
- No. It uses closed-form Rayleigh modes for an empty rectangular room, which is fast enough to run live in the browser. A real room with furniture and openings needs a full eigenmode or voxel solve, which is what the product's 3D solver does.
