How do I simulate a noise barrier?

Open this page and use the live Chladni Plates tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a noise barrier from your own measurements.

Mode n

Bow or drive a metal plate at a resonant frequency and sand sprinkled on top dances away from the moving areas and settles along the still nodal lines — Chladni figures. Each pair of mode numbers gives a different symmetric pattern, a direct, physical picture of a two-dimensional standing wave.

Governing equation

cos \frac{2 π x}{L} cos \frac{3 π y}{L} - cos \frac{3 π x}{L} cos \frac{2 π y}{L} = 0

Reading this result: Modes (2, 3) sum to an odd number, breaking the diagonal symmetry so the sand figure differs across the two diagonals.

About this simulation

The full Chladni Plates tool models a noise barrier with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
