Why has Teams Rooms background noise suppression capability been reduced?

Copper Contributor

Microsoft Teams Rooms background noise suppression options used to be 'Off, Low, Medium, High'


'High' used to provide a very good level of background noise suppression. We have a number of meeting rooms with mechanical ventilation and/or open windows that allow in external traffic noise - and 'high' used to cut it out almost entirely.


In the last month or two, 'Off, Low, Medium, High' have been replaced by 'On, Off'.


'On' does not work anything like as well as 'High' - remote participants report significantly increased background noise.

Hello @James_Smith_Birkbeck , 

Microsoft Teams Rooms background noise suppression options were categorized as 'Off, Low, Medium, High' for managing background noise during meetings.

However, it's important to note that Microsoft frequently updates its products and features, so it's possible that changes have been made since then.

If you have noticed changes in the background noise suppression options in Microsoft Teams Rooms, it is recommended to check for any recent updates or announcements from Microsoft regarding this feature. Visit the Microsoft Teams documentation or the Microsoft Teams release notes to see if there have been any changes or updates to the background noise suppression settings.

Additionally, if 'On' does not provide the same level of background noise suppression as the previous 'High' setting, you may want to explore other options to improve the audio quality in your meeting rooms. Here are a few suggestions:

1. Room Configuration: Ensure that the room is properly configured to minimize background noise. This includes adjusting the microphone sensitivity, positioning the microphones away from sources of noise, and considering acoustic treatments for the room if necessary.

2. External Noise Reduction: Explore options to reduce external noise sources in the meeting rooms. This could include improving sound insulation, adding noise-absorbing materials, or addressing ventilation and window-related noise issues.

3. Microphone Quality: Check the quality and condition of the microphones used in the meeting rooms. Poor-quality or damaged microphones can affect audio performance and noise suppression.

4. Acoustic Echo Cancellation: Confirm that the acoustic echo cancellation settings are properly configured. This feature helps eliminate echoes and improves audio quality during meetings.

5. Update Microsoft Teams Rooms Software: Ensure that your Microsoft Teams Rooms devices have the latest firmware and software updates installed. These updates may include enhancements or bug fixes related to audio quality and noise suppression.

If you have specific concerns or requirements regarding background noise suppression in Microsoft Teams Rooms, I recommend reaching out to Microsoft Support or consulting with your organization's IT department for further assistance. They can provide you with the most up-to-date information and guidance on optimizing audio settings for your meeting rooms.
