How to reduce background noise in Microsoft Teams calls

Cloud Telephony & Connectivity


We live in a busy and face-paced world, with lots of background noise. This might be the generic background noise of the open plan office, other colleagues chatting on the phone, the sound of traffic from an open window, or the sound of a dog barking.

Wouldn’t it be great if you could automatically filter out this background noise and have clear and uninterrupted calls and meetings?

Well, you can! There are settings built into Microsoft Teams – taking away the need to use the mute button.

How is background noise reduced?

This isn’t achieved through passive techniques, such as sound proofing padding on a set of headphones, (although this will still help and provide a level of comfort), but a very clever electronic method.

This method is known as Noise Suppression. Noise suppression is sometimes also known as “Active Noise Cancellation” and you may have already heard of these terms in the context of personal headphones and headsets.

Noise suppression algorithms are everywhere and more effective than ever. They are built into headphones, mobile phones and even smart speakers.  And it’s built into the Microsoft Teams client, so you are able to have clearer calls and meetings.

How do I use the Noise Suppression settings in Microsoft Teams?

Microsoft Teams tries adjust the Noise Suppression settings automatically, but sometimes you may want to tweak those settings depending upon your needs, and the tasks being performed.

You can change the Noise Suppression settings at any-time; before or during a call, and any amendment will be retained until it is next amended.

  • To enable or change the Noise Suppression settings, from the MS Teams client select Settings, then Devices.
  • Click on the Down arrow against Noise suppression, and select the required level. Any change is effective immediately and retained until next amended.

There are four Noise Suppression setting to select from:

1. Auto

The Microsoft Teams app will monitor the background noise and try to optimise the call quality. This is the default setting.

TIP: This is the best option to use unless there are specific requirements.

2. High

This suppresses all the background sounds which are not your voice.  This setting uses extra computer resources and the option may not be available if your computer does not support Advanced Vector Extensions 2 (AVX2). This setting is also unavailable if live captions are turned on, or the call/meeting is being recorded.

TIP: This is the best for environments where there is a lot of background speech.

3. Low

This setting suppresses low levels of persistent background noise, such as a computer fan or air conditioner.

4. Off

All noise suppression is disabled.
