How to fix audio feedback on microphones? 

Even the best microphone can feel like a poor product if you face technical issues like static, echo, and other similar problems. It can plague your audio fidelity and ruin your experience. They just might feel persistent and impossible to solve, but the right approach and a little bit of fundamental knowledge can help you solve these issues on your own in no time. Let’s help you drown out those irritating distractions.


Reasons for audio feedback

Before trying to solve any issue, you should understand the root cause. It will help you to tackle the problem in a holistic manner. Audio feedback is sometimes also known as a “Looped Signal”.

When you have a microphone, an amplifier, and one or more speakers in your audio setup, you have the possibility of facing this issue. To understand simply, audio feedback happens when the sound coming out of your speaker(s) makes it back into the microphone and is re-amplified. This creates an endless loop of echo.

How to fix it?

Audio feedback, ringing noises, static, squealing, and other such problems can be due to improper placement of hardware and misconfiguration of software settings, or a combination of these two. Here are a few things that you can to do tackle this situation.

1. The first thing to do is change the position of the microphone.

2. You can also change the direction of placement of any particular speaker you feel may feed audio output directly to the microphone.

3. Avoid placing the speakers directly toward any reflecting surfaces like smooth walls.

4. You can lower the output of the speakers and equaliser frequency to cope with the feedback loop.

5. You can use a directional or cardioid microphone as they pick sound only from what they are pointed at.

6. While using/speaking to the microphone, try to stay as close to it as possible.

7. You can wear headsets or in-ear monitors to limit audio feedback issues through speakers.

8. You can put the microphone on mute when you aren’t using it.

9. Sometimes, the static can be fixed just by unplugging and plugging the microphone again. You can also try a different port, sometimes, the issue can be from a specific port as well.

10. If the problem is still persistent you can always use an automatic feedback eliminator.
