    How do they plan to deal with all the ozone that will come off of those plasma speakers? I’ve made a plasma tweeter in the past and it sounded excellent, but the ozone it produced made it rather unhealthy to run for long periods of time.

      Can the ozone be countered by a reverse polarity static charge? Not sure how the laser printer do it, but recent printers barely emit ozone. I think it should be possible.

        Best thing would be to run it through am activated charcoal filter. That would catalyze (I think) the O3 to O2. Even HEPA filters would have no effect on ozone, as it’s a molecule made up of 3 oxygen atoms.

    This could be great for audiophiles and musicians, but it could also mean I don’t have to hear my neighbors fart through our paper-thin walls…where do I throw my money??

    “We wanted to reduce the effect of the membrane as much as possible, since it’s heavy,”

    Aren’t speaker membranes the lightest part of a speaker? I’d figure these things would still need amplifiers, would be highly dependent on where you sit (possibly amplifying unpleasant noise if you shift your position even a little bit due to phase), would generate ozone, and they don’t even really sound good when playing music, which means the ANC capabilities of them would be limited in the best case scenario.

    I don’t know. Other “whole room ANC” devices have come and gone and none of them seem to work. It’s a great idea in theory, but I don’t know if this tech is any different in nature to just using membrane speakers.

    ANC is already used in cars with moderate results, but you generally sit in one spot and there’s already speakers in your car.

      It is impossible to “cancel” noise in a room, because physics. Maybe you could cancel out some waves in some parts of a room, but you would probably intruduce your own waves in other parts of the room.

      My advice: get some foam/stone wool, plants, a couch, put a blanket on the wall and or ceeling. Absorb the waves. Active noise cancelation only really works in earphones.
