Suppressing background noise for video meetings

Last Updated:

The Zoom desktop client has options that utilize a noise suppression filter, which can help remove distracting noises that are picked up by your microphone and improve audio quality. Background noise, like paper crunching, keyboard typing, fan noise, dog barking, and other noises, will be filtered out to create a better meeting experience. By default, Zoom automatically mutes background noises that are picked up by your microphone; however, the option can be changed to be more or less aggressive based on the environment and use case.

Note: Adjusting the level of background noise suppression only affects your outgoing audio, and does not affect other participant's audio you receive in a meeting or webinar. 

Prerequisites for noise suppression

  • Zoom desktop client for Windows, 5.2.0 or higher
  • Zoom desktop client for macOS, 5.2.0 or higher

How to adjust background noises suppression in a Zoom meeting

  1. In the Zoom desktop client, click your profile picture, then click Settings.
  2. Click the Audio audio-button.png tab.
  3. Under the Suppress background noise section, select the level of suppression you wish to use:
    • Auto: This is the default setting, and will apply moderate background noise reduction when needed. It will auto adjust the aggressiveness for blocking background noise based on what it detects in the background. If music is detected, it will not treat the music as background noise.
    • Low: Noise reduction will be minimal. It will block low levels of persistent background noise.
      Note: This setting is best for casually playing music, as it will preserve as much of the original sound as possible. For highest fidelity when playing music, consider using the Enable Original Audio setting in your advanced audio settings.
    • Medium: Best for reducing and eliminating background noise in standard environments, including fans, pen tapping, etc.
    • High: Noise reduction will be at its most aggressive, and eliminate noise such as crunching of paper or wrappers, keyboard typing, etc. 
      Note: Enabling this option may increase CPU utilization.
