> These people have bought noise cancelling headphones, so when they join a meeting everyone else it bothered.

Noise cancelling headphones have directional mics that typically do a very good job of only picking up the wearer's voice.

If people really want to sound clear, a headset with a mic boom is every better. 0 background noise gets through.

These are all very well solved problems.

Heck my laptop back in 2005 (!!!) had a directional mic array. I could use an included utility app to control where in the room I wanted the mic to record from, I could record from in front of my laptop when going to lectures, or have the mics pointed at me when recording myself.

(That was a super cool laptop!)
