There is an integrated option called Sound Suppressions in Windows to help you reduce microphone background noise. You can follow the steps below to enable the noise reduction option.
- Type control in the search box and select the Control Panel app from the best match.
- Change the View by type to Category, and then navigate to Hardware and Sound > Sound
- Go to the Recording tab, and then right-click your microphone device and select Properties.
- Go to the Levels tab, and then lower the Microphone Boost level to +10dB and set your microphone volume to 100. This will make your mic easier to hear you.
- Go to the Enhancements tab, and then tick the checkbox for Noise Suppression or Noise Cancellation if it is available and click on OK and Apply to save the changes. If you are not wearing headphones, you can also tick the Acoustic Echo Cancellation option that can help reduce echo caused by speakers.
- The Enhancements tab may not be available depending on your audio hardware and drivers.
