Bass Trap Calculator
Quarter-wave resonator depth and porous absorber thickness targets.
How the bass trap calculator works
Choose a quarter-wave resonator or porous trap, set target frequency and speed of sound. The tool estimates required air cavity depth or mineral-wool thickness using lambda/4 relationships used in studio and listening-room design.
Key terms
- Quarter-wave trap - panel-and-cavity resonator tuned to a low frequency.
- Porous absorber - fibrous material that converts sound energy to heat; thickness sets low-frequency limit.
- Corner placement - increases effective path length for LF absorption.
Frequently asked questions
- Where should bass traps go? Corners and wall-ceiling junctions increase low-frequency effectiveness for both resonant and porous traps.
