2D acoustic treatment planner
Add panels, speakers and listener, then drag or move them with the keyboard.
Plan items
Select an item, drag it or use arrow keys. Delete removes the selection.
Room plan
Example
Example: a 4.2 × 3.4 × 2.6 m room with hard walls and partial panel coverage. Change one parameter at a time and compare saved variants.
Limitations
The result is a first-order model. Real reflections depend on geometry, furniture, gaps, mounting and the positions of the source and microphone.
FAQ
Does this replace a measurement?
No. It helps plan an initial variant and budget, but final decisions should be verified with an impulse-response measurement.
Are more panels always better?
No. One-sided absorption can leave bass problems unresolved and make the upper range too dry.
