What is Audio Feedback?

Audio Feedback is a phenomenon that occurs when a sound system’s output is picked up again by its input, creating a loop that amplifies certain frequencies. It is known for producing a loud, high-pitched squeal or hum.

The effect typically happens when a microphone captures sound from a speaker and sends it back through the system repeatedly, causing the signal to build up rapidly.

Audio Feedback emphasizes system interaction and gain levels, as it often occurs when volume is too high or microphones and speakers are positioned improperly.

It is commonly encountered in live sound environments, especially when microphones are close to speakers or when gain is pushed too far.

Today, Audio Feedback is an important consideration in sound reinforcement, valued for its role in guiding proper system setup, microphone placement, and gain control to maintain clear and stable audio.
