What Are Feedback Suppressors? How Does It Work???

When a sound loop occurs between an audio input and output, it creates audio feedback. This looped signal produces a screeching sound that is harmful to the speakers. This ear-piercing noise can cause permanent damage to your speaker and ears as well. Audio feedback means distortion of the signal. This problem can be prevented by using feedback suppressors

A feedback suppressor is a device that processes the audio signal and is used to prevent audio feedback in a sound reinforcement system. It is mainly used in live performances. 

Role of feedback suppressor in media:

Audio feedback is a common problem in live performances or live sound systems and it can easily ruin your show. At any frequency of sound, you may experience feedback. In short, audio feedback is a showstopper! 

But this problem can be overcome by feedback suppressors based on advanced technology. It can immediately detect problematic frequency signals and make necessary adjustments to suppress the feedback. This is done in less than one second before the human ears could even detect it.  

How does the feedback suppressor work?

A feedback suppressor detects the frequency of sound that causes feedback. It then places a notch filter at that troublesome frequency and automatically lowers the volume when the sound reaches that frequency. However, to avoid feedback in live situations you must use a directional microphone and speak close to the mic. The microphone should be turned off when not in use.

Benefits of feedback suppressor:

Feedback suppressors are a great help to avoid annoying screeching sounds in live situations. They are being used worldwide and have been proven to help in feedback suppression.
