The AI-based, real-time noise suppression that was added to Windows desktop client for Microsoft Teams in Nov 2020 will soon also be available on MAC. This feature will automatically remove background noise from your meetings.

You can set the noise suppression level before a meeting. Once changed, the setting applies to the next call.

The four settings are Auto (default), Low, High, and Off.

They are accessible from the profile image > Settings prior to a meeting and from More options  > Device settings during a meeting.

When left on the default setting, Auto, the Teams app sets noise suppression based on ambient sound.

  • Low is designed for persistent background noise like an air conditioner, computer fan, or music.
  • (New) High suppresses all background sound that is not speech; this setting uses more computer resources.
  • Off disables the noise suppression feature.

Note: The high setting is unavailable for Mac Users with M1 Arm Processor

Availability:
Rolling out late April to late August.
