> Used this way, the thin-film loudspeaker could provide active noise cancellation in clamorous environments, such as an airplane cockpit, by generating sound of the same amplitude but opposite phase; the two sounds cancel each other out.
Not mentioned here is that to achieve this you need to track heads in real time (i.e. with a camera) - the phases need to align at just the right spot - which might be worth the creepiness tradeoff or not idk.
Actually, it looks more like isolating the whole cockpit (or room) with the "paper" to the noise is cancelled before entering the cockpit.
You could imagine a recording studio with 2 sheet of this:
- sheet against the wall to cancel the outside sounds coming INTO the recording room
- sheet against the previous one (but turn oppositerly) to cancel the sound from the recording room to go outside the room
Neither of those things would work because the objectionable noise is deep into the bass, which this stuff can't do with the excursion limits it's working with.
