There could be a few reasons why the ambient noise is louder than your voice during a Teams conference, even with noise cancellation set to high.
One possibility is that the microphone on your device might not be picking up your voice as well as it should be. You might want to try adjusting the microphone settings in Teams to see if that helps.
Another possibility is that there might be some other software or application running on your device that is causing the ambient noise to be picked up by the microphone. You could try closing any unnecessary applications or programs to see if that helps.
Finally, it's also possible that the issue could be with the other participants in the conference, and not with your device. You might want to ask them if they're experiencing the same issue, or if they can hear you clearly.
