Noise detection – yes - we've had it for a while now - https://blogs.cisco.com/collaboration/cut-background-noise-out-of-meetings

Background noise is notified by the AI feature. We don't automatically mute the line where the noise is coming from because people may think Webex is buggy and auto muting without a reason. Instead, we detect and notify you of background noise and give you the choice to mute - or unmute - your line when the system sees you are speaking.
