Reduce echo during online course

Echo is the common issues that users are faced with while on a video chat. It's distracting, annoying, and half the online course is spent troubleshooting the issues. If someone can't figure out how to eliminate their echo, you breed a silent resentment for the person who can't seem to understand the gravity of the annoyance they are creating. Next thing you know, all focus is lost and the course has taken a turn for the worse.
Here are steps you can take to locate the source of the problem and resolve it quickly.
• If you are using external speakers, place the speakers far away from the laptop mic and reduce the volume to a comfortable level.
• For those who have external microphones, move the microphone about a foot away from the speakers. Avoid typing on an unmuted mic and step back from the laptop when using hands-free mode. You can also reduce the volume microphone level to 50% or less and reduce or turn off the microphone boost option.
• Some computers have an echo cancellation feature but it could be compromised on high CPU load. Closing a few processes can help enable that feature.
• Ask if there is anyone on the call who does not hear the echo. The participant who can't hear the echo is usually the source of it.
