Reduce background noise in Microsoft Teams meetings

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 to help keep meeting participants focused on the following platforms: the Teams desktop app, the Teams mobile app (iOS and Android), Microsoft Teams Rooms on Windows, and Windows Azure Virtual Desktop (AVD).

Turn on noise suppression

You can change this setting at any time. Noise suppression is turned on by default, but you can change the setting in Teams. The setting you choose will carry over to your next meeting or call.

1. In Teams, select Settings and more 👁 Teams settings and more icon.
