Turn room dimensions, a current and target RT60, panel area and a product absorption coefficient into a staged, measurable treatment plan.
How many acoustic panels should I plan first?
Use a measured mid-band RT60 where possible, calculate the added absorption needed for a chosen target, buy a staged quantity, then measure again. A coverage percentage alone cannot prove the result.
Method
Metric Sabine working estimates current and target absorption from room volume. Whole-panel quantity uses the entered panel face area and product absorption coefficient, with a separate surface-coverage cross-check.
Important limitation
This is a first-order mid-band plan. Small-room modes, low-frequency decay, non-uniform placement, doors, openings and measurement quality can dominate; remeasure before the next purchase stage.
