Noise-canceling robots to ‘mute’ loud conversations in cafe | What if we told you that we can actually silence a noisy table right next to us in a café?::undefined

Besides what you mention, I have my reservations about ‘crazy revolutionary’. If I remember correctly, noise cancelling only works in one very concentrated spot where the waves are measured and cancelled out. If you move a couple of inches, the cancellation isn’t perfect anymore and does practically nothing. That’s why ANC headphones work well (always right by your ear) but any other open application seems implausible to me.
