When your mic is turned on in a Teams meeting or call, background noise around you—shuffling papers, slamming doors, barking dogs, and so on—can distract others. Teams offers three levels of noise suppression for the Teams desktop app to help keep meeting participants focused.
You can change this setting at any time. Once changed, the setting carries over to your next meeting or call.
To affect the noise suppression level for a meeting you’re currently in, use the second procedure.
• Auto (default) The Teams app decides on the best level of noise suppression based on local noise.
• High Suppresses all background sound that isn’t speech.
