“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.
