Highly doubtful, it's just a microphones and the speakers that emit inverted sound waves.
This is one of the safest technologies I can imagine.
It's more likely that the radio waves from wireless communication (phones, Bluetooth headphones etc) will have negative impact, but even that's unlikely at this point, considering how widespread their use is and no statistically significant link exists.
Sure but it's combined noise on top of existing sound waves that gets me. They don't cancel out midair, they cancel out in your brain right?
And yeah, I also don't trust all these radio waves we have going everywhere and wonder if big events with hundreds of thousands of phones are doing at least some damage.
Things seem unlikely til we realise. Like plague spreading through bad smells. We were close but dismissive.
Anyway I hope I'm not right, but it still plays in my mind.
> don't cancel out midair, they cancel out in your brain right?
No, they cancel out in front of your ears. If you imagine a bowl of water which has waves on it with a small buoy, then the noise cancelling is another wave emitter placed in front of the buoy that cancells out the Waves that are about to hit the buoy.
It's a very physical technology. The amazing/magical part of it is that the microphones pick up the Waves quickly enough for the headphones to emit the inverted wave.
Okay I just assumed it was both waves coming to shore and they fell in such a way that lessened both of them. But if they're colliding outside the ear then I feel a bit better now.
