Microphone Echo Test & How to Fix Mic Echo on PC & Calls

Reviewed by AudioSolver editorial team3 min read

Hearing your own voice repeat with a half-second delay, or having callers complain that you are echoing, is one of the most frustrating audio problems. Isolate whether the echo is caused by physical acoustic feedback or a software loopback setting.

The 2 Types of Microphone Echo (And How to Tell Them Apart)

  1. Physical Acoustic Feedback: Your microphone capsule is physically hearing the sound coming out of your desktop speakers or open-back headphones. When you speak, the caller’s voice (or your own voice returning from the server) plays out of your speakers, enters your microphone, and loops back into the call.
  2. Digital Software Loopback (“Listen to this device”): A sound driver or Windows setting is digitally feeding your microphone input directly into your headphone output stream. This results in an immediate, zero-latency or near-zero latency echo in your own ears even when you are not in a call.

Step 1: Disable “Listen to This Device” in Windows

If you hear your own voice echoing in your headphones even when all apps and browsers are closed:

  1. Press Win + R, type mmsys.cpl, and press Enter to launch the Sound Control Panel.
  2. Switch to the Recording tab.
  3. Double-click your primary microphone to open its properties.
  4. Click the Listen tab at the top.
  5. Ensure “Listen to this device” is UNCHECKED. If it was checked, uncheck it, click Apply, and the echo will instantly vanish.

Step 2: Eliminate Acoustic Speaker Bleed

  1. Wear headphones during calls: Never use a standalone desk microphone with external desktop speakers unmuted during voice communication. Even the best AI filters struggle to cancel loud speaker audio.
  2. Position a cardioid mic properly: Direct the front of your microphone towards your mouth and the dead rear null towards your keyboard and monitors.
  3. Lower headphone volume: In high-sensitivity condenser mics, loud audio leaking through foam headphone cushions can trigger feedback.

Step 3: Enable Echo Cancellation in Discord & Zoom

  1. Discord: Go to Settings > Voice & Video. Scroll to Voice Processing and toggle Echo Cancellation to ON.
  2. Zoom: Open Settings > Audio. Set Background Noise Suppression to Auto or Medium, and ensure Original sound for musicians is disabled unless you are performing an instrument.

Quick answers

Frequently asked questions

Why is my microphone echoing during calls?

Microphone echo occurs when audio playing from your speakers or open-back headphones physically bleeds into your microphone capsule (acoustic feedback), or when Windows loopback ('Listen to this device') is accidentally enabled.

How do I disable microphone echo in Windows 11 and 10?

Press Win + R, type 'mmsys.cpl' and press Enter. Click the Recording tab, double-click your microphone, go to the 'Listen' tab, and uncheck 'Listen to this device'. Click Apply and OK.

Why do meeting participants hear an echo when I talk?

If other participants hear an echo of themselves, someone in the call has their microphone sensitivity too high near unmuted desktop speakers, or their communications app has disabled Acoustic Echo Cancellation (AEC).
