How to Calculate Acoustic Panel Coverage
Formula
Total Wall Area = 2 x (Length + Width) x Height
Target Area = Total Wall Area x Coverage %
Panels Needed = ceil(Target Area / Panel Area)
Coverage Guidelines
Focus panels on the first reflection points (side walls at ear height) and the wall behind the listening position for the greatest effect.
Example Calculation
An 18 x 14 foot room with 9-foot ceilings, 30% coverage using 24x48 inch panels.
- 01Total wall area = 2 x (18 + 14) x 9 = 576 sq ft
- 02Target coverage = 576 x 0.30 = 172.8 sq ft
- 03Panel area = (24 x 48) / 144 = 8 sq ft each
- 04Panels needed = ceil(172.8 / 8) = 22 panels
