Acoustic Treatment Calculator

About this calculator

Acoustic treatment uses absorptive panels to reduce sound reflections off hard, parallel surfaces that otherwise cause flutter echo, standing waves and comb-filtering in a room. As a practical rule of thumb, treating roughly 15–25% of a room's total wall and ceiling surface area with absorption panels at the first-reflection points is enough to meaningfully tighten the room's sound without over-damping it into a dead, lifeless space; this calculator takes your room dimensions, a target treatment percentage, and panel size to estimate how many panels that requires.

Home studio owners, podcasters, and audio engineers treating a control room or vocal booth use this kind of estimate before buying foam or fiberglass panels, since under-treating leaves audible ringing on recordings while over-treating kills the natural ambience a mix needs to translate well on other systems. It's a starting budget for a treatment plan, not a substitute for measuring reverb time (RT60) or mapping first-reflection points with a mirror test.
