How to Use the Acoustic Panel Calculator
One of the most common mistakes when treating a home studio is covering every wall with acoustic panels. In reality, treating only part of the wall surface is usually enough, and over-treating a room can make it sound overly dead and unnatural. This calculator takes your room's width, length, and height along with a target coverage ratio, then computes the wall area that actually needs treatment and the number of standard 2x2 ft panels required.
The target coverage ratio depends on how you use the space. A vocal booth that needs to minimize reverb as much as possible should aim for 30% or more, while a general mixing or monitoring room typically works well around 20-25%. Prioritizing the first reflection points on the walls between your speakers and listening position gets you the most improvement from the fewest panels. If ceiling reflections are an issue, adding panels to part of the ceiling helps too.
The panel count assumes standard 2x2 ft (24x24 in) panels roughly 2 inches thick. If you're buying panels in a different size, divide the calculated area by the area of one panel to convert. Corner bass traps are especially effective at absorbing low frequencies, so if budget allows, prioritize placing traps in the room corners first.
Frequently Asked Questions
No. Covering just 20-30% of your wall surface is usually enough to significantly reduce reflections. Prioritize the first reflection points between your speakers and listening position for the best effect.
This calculator assumes standard 2x2 ft (4 sq ft) panels. If your panels are a different size, divide the required area by the area of one panel to convert.
