Why Reduce Mic Background Noise in Windows 11?

Background noise can ruin the experience in online calls, recordings, and streams. Common sources include:

🖱️ Keyboard typing and mouse clicks
💻 PC fans or laptop cooling noise
🚪 Room echo or environment sounds

Method 1: Enable Built-in Noise Suppression in Windows 11

Windows 11 includes a background noise reduction feature for supported devices.

Steps to Enable Noise Suppression

Press Windows + I to open Settings.
Go to System → Sound.
Under Input, select your microphone.
Look for Audio enhancements or Noise suppression.
Toggle it On.

👉 Once enabled, Windows will automatically reduce unwanted background noise during calls and recordings.

Method 2: Adjust Microphone Properties via Control Panel

If you don’t see noise suppression in Settings, you can tweak mic settings manually.

Steps:

Right-click the Speaker icon in the taskbar → Sound settings.
Scroll to Advanced → More sound settings.
In the Recording tab, select your microphone → Properties.
Go to the Levels tab → Lower the mic boost if it’s too high.
Go to the Enhancements tab → Enable Noise Suppression or Acoustic Echo Cancellation (if available).
Click Apply.

✅ This method works even on older devices without the new Windows 11 noise suppression toggle.

Method 3: Use App-Specific Noise Cancellation

Most communication apps have their own built-in noise suppression.

In Microsoft Teams

Open Teams → Click your profile picture → Settings.
Go to Devices → Under Noise suppression, select:
- Auto (default)
- High (maximum suppression)
- Low/Off (minimal suppression).

In Zoom

Open Zoom → Settings → Audio.
Check Suppress background noise → Choose Auto, Moderate, or Aggressive.

In Discord

Go to User Settings → Voice & Video.
Under Noise Suppression, enable Krisp (built-in AI noise cancellation).

👉 These options work alongside Windows settings for best results.

Method 4: Use Third-Party Noise Cancellation Software

If you want professional-grade audio cleanup, third-party apps can do wonders:

Krisp – AI-powered, removes keyboard clicks, traffic, pets, etc.
NVIDIA Broadcast – For RTX GPU users; offers studio-quality noise removal.
Voicemeeter Banana – Free virtual audio mixer with noise gate features.
OBS Studio Filters – For streamers; add noise suppression filters directly.

These tools are great for podcasters, streamers, and professionals.

Method 5: Optimize Your Mic Setup for Less Noise

Sometimes the best fix is physical, not digital. Try these simple tweaks:

🎧 Use a headset mic instead of your laptop’s built-in mic.
📏 Keep the mic closer to your mouth (6–8 inches).
⬇️ Lower mic sensitivity in settings to reduce background pickup.
🏠 Choose a quiet room and close windows/doors.
🧽 Add foam pop filters or desk stands to absorb sound.
