How the feedback margin calculator works
Distance from microphone to speaker, critical distance, microphone directivity, and current system gain feed a simple stability estimate: maximum gain before feedback and remaining margin in dB.
Key terms
- Acoustic feedback - loop where loudspeaker energy re-enters the microphone and regenerates.
- Feedback margin - headroom between operating gain and unstable gain.
- Critical distance - room-related boundary between direct and reverberant pickup.
Frequently asked questions
- How can I reduce feedback risk? Increase mic distance from speakers, use directional mics, and add absorption to raise critical distance.
