Acoustic Treatment Panel Coverage Calculator
Calculate how many acoustic panels you need to treat a room for recording, podcasting, or home theater.
Based on room dimensions and treatment goals.
Why Acoustic Treatment Matters Untreated rooms produce reflections, flutter echo, and standing waves that color the sound and make recordings sound amateur. Acoustic panels absorb mid and high frequencies, reducing reverb and improving clarity.
What Acoustic Panels Do (and Don’t Do) Panels absorb mid/high frequencies (roughly 250 Hz and above). They reduce reverb time and early reflections — not soundproofing. To block sound from leaving or entering a room, you need mass (drywall, concrete) — not panels.
Treatment Coverage Guidelines The percentage of wall and ceiling surface area to cover with panels depends on use:
- Light / Podcast (15–20%): Tame the worst reflections. Good for spoken word and video calls.
- Voice Recording (25–35%): Tight, dry vocal sound. Suitable for home recording vocals.
- Music Recording / Studio (40–60%): Controlled environment. Required for mixing and mastering.
First Reflection Points Always treat these locations first:
- Side walls — where sound reflects from your speakers to your ears
- Rear wall — behind the listening position
- Ceiling — between the speakers and your ears (reflection triangle)
- Front wall behind the monitors (for recording booths) Corner bass traps address low-frequency buildup and should be added separately.
Panel Area Formula Total surface = 2×(W×H) + 2×(L×H) + (W×L) [5 surfaces excluding floor] Panel area = (Panel width in) × (Panel height in) ÷ 144 sq ft Panels needed = Ceiling(Total surface × Coverage % ÷ Panel area)
