feedback sounds

Feedback sounds occur when a microphone picks up a loud, continuous squeal caused by sound from speakers being re-captured by the mic. This creates a loop where the sound is amplified repeatedly, resulting in high-pitched, unpleasant noise. Feedback often happens when microphones are placed too close to speakers, or when the volume is set too high. To prevent it, sound engineers adjust microphone placement, lower volume levels, or use equalizers to reduce specific frequencies that feed back. Understanding and managing feedback ensures clear, enjoyable sound in live performances and public address systems.
