Add a finish or treatment#
You’ll need: The room open in Room Analysis, with its baseline Reverb Time noted so you can compare.
Choose the surface and material#
- Select the wall, floor or ceiling in the room diagram or surface table.
- Click Add Finish for a finish, or Add Treatment for acoustic treatment.
- In Surface Material Editor, select the material and look over its absorption data.
Set coverage and apply#
- Choose Area or Percent, then enter the amount.
- Click Apply once and wait for calculation and saving to finish.
If Use Recommended is shown, it proposes an amount. Treat it as a starting point and judge it by the updated result.
Check the saved assignment#
A new row in Surface Composition shows the material, its role and the coverage that was saved.
Return to Reverb Time and compare the updated prediction with your baseline. If Apply doesn’t complete, read its message — the row shows what was actually saved.
Apply coverage to several surfaces#
You’ll need: Several surfaces selected, with Add Finish, Add Treatment or Edit open.
Choose how the amount is shared#
| Choice | What happens |
|---|---|
| Each selected surface | Every selected surface gets the full amount. |
| Total across selection | One total amount is shared across the selection. |
| By surface area | The shared total is split in proportion to surface area. |
| Even split | The shared total is split evenly, where this option is available. |
The options shown depend on your selection and coverage mode. Choose deliberately: 10 m² on each of four walls is 40 m² in total, not 10 m².
Check the saved coverage#
Select each affected surface and confirm its coverage row matches what you intended. Then compare Reverb Time against the same target.
