So cool. Is this basically like 2 inaudible waves coming together in an "overlap spot" to create an audible moment?

- adrian_b 2y agoYes. Since they are ultrasound waves, they are inaudible for humans, but they may be audible for various animals and for ultrasound detecting devices.
- ahofmann 2y agoYeah, the whole concept sounds to me like "let's fire a lot of high energy beams into a crowd, it will be fine".
- arrobbiato 2y agoI’m firmly convinced that a lot of the acoustic tricks that AirPods Pro do to achieve noise canceling involve ultrasonic harmonics, perhaps unintentionally - and this has created an epidemic of tinnitus among their users.
- volemo 2y ago> and this has created an epidemic of tinnitus among their users Excuse me, are there sources I can read more about this?
- cadamsdotcom 2y agoIf there aren’t, please don’t spread the rumor. You might accidentally trick people into thinking it’s true. Big claims require big evidence, and so far, this has none.
- volemo 2y agoThat’s exactly why I was asking for sources.
- ahofmann 2y agoBig accusations require strong evidence. Please provide them, if you have them. I'm not an expert. 99% of my “knowledge” about ultrasound is from the posted article. Your thought process around AirPods makes no sense to me. I would be very surprised if active noise-canceling systems would produce sounds higher than 20KHz.
