Avoiding Audio Feedback: A Practical Guide for Events & Presentations

What is Audio Feedback? Audio feedback happens when the sound from a speaker or monitor is picked up by a microphone, amplified, and then re-captured in a loop. This loop creates the loud, high-pitched noise everyone dreads. Common Causes of Feedback Understanding the root of the problem is the first step: - Microphones too close to speakers Excessive microphone gain (volume too high) - Multiple open microphones on stage - Poor venue acoustics with echo or reverberation - Inadequate sound system setup. Best Practices to Prevent Feedback Microphone Technique: - Hold or position the microphone close to your mouth. - Avoid pointing it toward speakers or monitors. - Use directional microphones (cardioid or super-cardioid). Sound System Setup: - Position speakers in front of microphones, not behind. - Angle speakers away from stage microphones. - Use in-ear monitors instead of stage wedges. Audio Settings & Mixing: - Keep microphone gain at a reasonable level. - Use an equalizer (EQ) to cut problematic frequencies. Mute unused microphones immediately. Room Acoustics Matter The venue itself can cause issues. Hard surfaces like glass or concrete reflect sound, making feedback more likely. Using curtains, carpets, or acoustic panels helps absorb sound and reduce echo.

Quick Fixes During an Event Even with preparation, feedback can happen. Here’s how to react: - Lower the volume on the affected channel. - Step away from the speaker or monitor. - Check for open or unnecessary microphones. - Have a sound technician monitor levels at all times.
