# Why is my microphone echoing or buzzing?

If your microphone produces an **echo**, **buzzing**, or **feedback noise** during a test or interview, it can significantly reduce audio clarity and may interfere with communication or automated proctoring checks.

In this article, we explain the most common reasons for microphone echo or buzzing and the steps you can take to resolve the issue quickly.

## ✅ Common Causes and Fixes

| **What Might Be Wrong**                     | **What You Can Do**                                                                                           |
| :------------------------------------------ | :------------------------------------------------------------------------------------------------------------ |
| Microphone too close to speakers            | Move the microphone away from your **laptop speakers** or any **external speakers** to reduce audio feedback. |
| Using built-in mic and speakers together    | Use **wired headphones or earphones** to prevent internal audio looping and echo.                             |
| Faulty microphone hardware                  | Test with a **different microphone or headset** to rule out hardware issues.                                  |
| Loose or damaged mic cable                  | Reconnect the microphone securely and avoid using **frayed or damaged cables**.                               |
| Microphone input volume too high            | Lower the **mic input/gain level** in your system or audio settings.                                          |
| Outdated or unstable audio drivers          | Restart your device or **update audio drivers** to refresh the connection.                                    |
| Echo cancellation disabled                  | Enable **echo cancellation or noise suppression** in your browser or system audio settings.                   |
| Background noise or electrical interference | Move to a **quieter room**, avoid power-heavy devices nearby, or use a **noise-canceling microphone**.        |

  ### Additional Tips

  If the issue persists, try the following:

  * Restart your device and rejoin the session
  * Ensure the **correct microphone** is selected in your browser or system audio settings
  * Disconnect and reconnect any external audio devices
  * Avoid using Bluetooth audio devices if possible, as they may introduce latency or interference

## 🛠 Final Check: Test Your Microphone

Before joining your interview, verify your mic is working clearly.

👉 [Run a Mic Test](https://www.notion.so/1d73461472f38001a772e238965c2d4a?pvs=21) to confirm it's working well.

You should see yourself and hear audio from your mic input.
