Room Mode Analysis
Room modes are the resonant frequencies of a room, determined entirely by its geometry. At these frequencies, low-frequency standing waves build up and cause uneven bass response — common problems in recording studios, home cinemas, and any critical listening environment.
The Room Mode Analysis tool uses wave-based finite element simulation to calculate these resonance frequencies directly on your SketchUp model geometry. No material assignment is required.
How to run
- Click the Room Modes button in the SketchAcoustics toolbar
- Select all faces that form your room boundary — walls, floor, and ceiling and press
Enter - Configure the analysis settings (frequency range, resolution)
- Click Run
- Results appear in the dialog, and a 3D pressure visualisation overlays your model
You can unselect all selected surfaces by presing Esc
Tips
- You don’t need to assign acoustic materials — room modes are purely geometry-dependent
- Include all six boundary surfaces (four walls, floor, ceiling) for accurate results
- The 3D pressure overlay shows which areas of the room experience the highest pressure buildup at each mode frequency
