Feedback Cancellation

Feedback cancellation is a technology used in audio systems to prevent a loud, high-pitched noise called a "whistle" or feedback loop. This happens when a microphone picks up sound from speakers and amplifies it repeatedly. Feedback cancellation works by detecting the specific sound pattern causing the loop and then generating an opposite signal to cancel it out. This process allows microphones and speakers to work together loudly and clearly without producing annoying squeals or howls, ensuring clear audio quality during conferences, concerts, or public address systems.
