Monitor placement
Set the desk and monitors against the short wall where practical, then place the listening position deliberately before building treatment around it.
Australian acoustic planning tool
Accurate analysis.
Practical plan.
Better room.
Room Report is for home studio acoustic treatment and bedroom studio acoustic treatment. Measure the room, calculate the constraints, then build a considered plan.

MEASURE
Dimensions set the low-frequency problem.
CALCULATE
Physics first. Practical decisions second.
PLAN
Buy materials for the problem you actually have.
Deterministic acoustics. Input in. Plan out.
Free tool / axial modes
Room acoustic treatment calculator
Start with the room. Enter the internal dimensions to see the first axial modes along each wall pair. No email required.
Axial mode formula: f = (343 / 2) × (n / d). This is planning guidance, not an in-room measurement or performance guarantee.
Calculated output
c = 343 m/s · first six orders up to 200 Hz
Length modes
- n=140.8 Hz
- n=281.7 Hz
- n=3122.5 Hz
- n=4163.3 Hz
Width modes
- n=149.0 Hz
- n=298.0 Hz
- n=3147.0 Hz
- n=4196.0 Hz
Height modes
- n=171.5 Hz
- n=2142.9 Hz
Near-coincident clusters
No modes in the displayed range land within 3 Hz of each other across room dimensions.
Full report / preview
A build plan, not a shopping list.
The full Room Report turns complete room inputs into a specific treatment sequence, materials schedule and downloadable planning PDF. The current flow is an explicit demo preview; checkout is not wired.

Mode analysis
Axial, tangential and oblique mode analysis with the frequencies that need attention.
02
Workable ratio
A practical room-ratio check using Bolt area, with the limitation stated plainly.
03
Listening geometry
Desk, monitor and listening-position reasoning based on your entered room.
04
Build order
Bass trapping first, then first reflection points, then a ceiling cloud.
05
Material schedule
Panel dimensions, insulation density, thickness, air gap and a hardware-store cut list.
06
Cost and restraint
An estimated AUD materials total and a short note on purchases that do not solve the stated problem.
Treatment principles
Start where the room needs it.
A useful plan puts treatment in order. It does not turn every surface into a panel or sell foam as a cure for low-frequency problems.
Bass traps
Corner bass trapping is the first treatment priority when room modes dominate the low end.
Acoustic panel placement
Treat first reflection points only after the listening geometry is set, then add the ceiling cloud where it serves that geometry.

Technical limitation: Room Report is a planning tool, not an in-room measurement service or acoustic-performance guarantee. It uses the dimensions and details you provide; final treatment decisions should account for the actual room and verification measurements where needed.
