Frequently asked questions

Why not just give a single panel count?
Midband absorption, bass trapping, and early-reflection control solve different problems. A flat "buy 12 panels" answer usually under-treats corners and over-treats random wall space, so this quiz breaks the estimate down by role instead.
What is RT60 and why does the quiz estimate it?
RT60 is the time it takes sound to decay by 60 dB after the source stops — the standard measure of how "live" or "dead" a room sounds. The quiz uses the Sabine equation on your room volume and construction to estimate current RT60, then sizes absorption to bring it into a usable range.
