Newline Smartboard Interactive Panel: What to do if there is an echo

Troubleshooting Echo

Echo in Google Meet/Zoom is primarily caused by audio feedback, where a microphone picks up sound from speakers and replays it, creating a loop.

Common Causes of Echo

The first thing to do is to identify the source of the echo. The person hearing the echo is usually not causing it, in which case it is coming from someone else in the meeting. Echo can be caused by:

• Audio feedback loops: The most common cause is the microphone picking up audio output from speakers. If you've placed your external microphone in close proximity to your speakers, it will cause a feedback loop.
• Multiple devices: Joining a meeting from two or more devices (e.g. laptop and phone) in the same room creates severe feedback.
• High speaker volume: If your volume is set too high, it will cause sound to leak and be picked up by the microphone.
• Raw hardware issues: If you are using improper or malfunctioning audio equipment, please contact the IT Department.

How to Fix Echo

The primary microphone in your meeting should be the one on the Newline board! If you are in a meeting where multiple people in the same room as the Newline board have joined, there is a higher chance that echo will occur if you don't follow the best practices:

• Use headphones/earphones (for remote users). This is the most effective way to separate microphone input from speaker output.
• Mute your microphone when you're not speaking. This reduces the chance of your microphone picking up ambient noise or other speakers.
• Lower the volume of your speakers. Decrease the speaker volume to prevent the microphone from picking up the sound.
