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).

Set the noise suppression level

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.

From the main Teams window

  1. Select Settings and more Teams settings and more icon. next to your profile picture and then select Settings.

  2. Select Devices on the left and then, under Noise suppression, select an option.

    Teams-settings-noise suppression

    • Auto (default) The Teams app optimizes for some level of noise suppression and is best for most situations.

    High Suppresses all background sound that isn't your voice and is best for noisy office environments with a lot of background speech.

    Low Suppresses low levels of persistent background noise, such as a computer fan or air conditioner. Use this setting to play your choice of music for other meeting participants to hear, like when waiting for a meeting to start. For the highest fidelity when playing music for other participants in a Teams meeting, see Share sound from your computer in a Teams meeting or live event.

    Off Noise suppression is disabled. Use this setting for high-fidelity microphones in low noise environments like a quiet studio.

From a meeting window

  1. Select More  More options button  in your meeting controls and under Settings then select Device settings.

  2. Under Noise suppression, select an option. (See step 2 above for option descriptions.)
