Mic Echo Problem: Why People Hear Themselves

Use the echo test to find out whether your microphone hears your speakers, then fix it. Headphones are the surest cure.

Press Start, then choose Allow when your browser asks to use the microphone.

How to run the echo test

  1. Press Start mic test and allow the microphone.
  2. Set your speakers to the volume you normally use for calls. Leave headphones off if you want to test your speakers.
  3. Press Echo test and stay quiet. The page plays a short tone for about two seconds.
  4. Read the result: “Your mic hears your speakers” means echo is likely in calls.
How the result is worked out. Example with made-up levels: the 1 kHz band measures −90 dB before the tone and −72 dB while it plays, so the rise is 18 dB. We call a rise of 15 dB or more a strong echo, 6 to 15 dB a slight one and under 6 dB none. These limits are our own rule of thumb.

How to stop microphone echo

  • Use headphones or a headset. No sound from the speakers reaches the microphone.
  • Turn the speakers down and move the microphone away from them, or closer to your mouth.
  • Only one device per call. If two devices in the same room are in the same call, each hears the other.
  • Test again after every change, and compare with “Use the browser’s sound processing” ticked: browsers can apply echo cancellation when an app asks for it.

Browser echo cancellation: MDN Web Docs, MediaTrackConstraints.echoCancellation. The other tips are general acoustics, not vendor settings; we do not give operating-system menu paths for echo here because we have not verified them against the vendors’ pages.

Frequently asked questions

Why do people hear themselves when they talk to me?

The usual cause is that your microphone picks up the sound from your speakers and sends it back. Whoever talks hears their own voice a moment later as an echo.

How do I stop the echo?

The most reliable fix is headphones or a headset, because the sound then no longer reaches the microphone. Otherwise lower the speaker volume and keep the speakers away from the mic.

What does the echo test on this page do?

It stays quiet for 1.5 seconds to measure the 1 kHz background, then plays a short 1 kHz tone through your speakers and checks how much louder that frequency becomes at the microphone. A big rise means your microphone hears your speakers.

The echo test says no echo but others hear echo. Why?

The echo may come from the other person’s side, or the speakers were too quiet or muted during the test. Run it again with the speakers at the volume you normally use. Headphones always give a clean result.

Does browser echo cancellation help?

Browsers can apply echo cancellation to the microphone when a web app asks for it (the echoCancellation setting). This page leaves it off by default so the test shows the raw situation; tick the processing box in the test to compare.
