# What can I do to prevent echo or feedback?

## Follow the steps below to prevent echo or feedback when using your microphone

BigMarker and your browser utilize a range of background processes designed to minimize any echoes that may occur while you speak into your microphone. However, there are situations where you can still hear an echo or feedback. Learn more about the possible reasons, preventative measures and fixes for unwanted echo and feedback. 

***Reasons for an echo or feedback:***

- Echo occurs if input output **audio devices are placed close together**. Someone's computer speakers are too close to their microphone or their audio is too loud.

- **Being in the same webinar twice**. If you hear an echo and notice that someone is in the room twice, that maybe the cause.

- Having **multiple people in the same physical office** or room in the same web conference room (sound from the speaker on one computer enters the microphone of the other computer).

***Prevention:***

- **[Wear a headset or ear buds,](https://kb.bigmarker.com/knowledge/hardware-recommendations?hsLang=en)** removing any possibility of you speaker audio going into your microphone.

- If you or someone else is in the room twice; remove them, exit or close any extra windows or tabs.

- **Refresh** the page.

- Move your microphone away from your speakers.

- **Mute or turn off the microphone** of the person who is causing it or mute yourself if you are the cause. Mute others when they are idle.

- Have the person who is causing it, **turn down their computer's volume**.

- If multiple people are on multiple computers in one physical location, have them go in separate rooms or turn off or mute all the computers but one.

- Buy or use an **external microphone**. Built-in mics quality can vary.

- **Turn off webcams**. This will allow more bandwidth for audio.
