that means the person giving you signals is better at chess than you

Def not, that’s how cheating is done in online games: you replicate the game and have a computer suggest the next move.

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.
