and here I though it would use noise cancellation
hit their voice with the opposite soundwave and it cancels it out, while they can still talk, the sound won't make it to you, or it'll be significantly reduced
The problem with that is that the soundwaves will have to be produced at nearly the same time for that effect.
Which is difficult in speech, as it's unpredictable and the frequencies go all over the place.
It works fine with static equipment, such as machinery.

Fox News better hope I never get my hands on that gun.
Actually, we already have a gun that can shut people from Fox News up. No seriously! We can go to any electronic store and pick it up for 10 dollars (or around that range). Its cheap and doesn't hurt them at all, and it will shut them up every time! Its called a remote control.
On-topic: I'm not sure how the technology actually works, but maybe a visual example (like a youtube video) might help explain it. If this works, I would love to have one of those around the house. >.>
When you talk, as the article tries to explain, you don't only "talk". You listen to your own voice to properly control it. One of the ways this becomes appearant is if you put on headphones with loud music and start talking to someoene - most likely your voice will be much louder, as you can't hear it properly yourself.
In most people this goes automaticly, but once you listened to a deaf person trying to speak you'll know what I mean.
This technology takes what you said and throws it back at you only a few milliseconds later. This messes up that feedback system in your brain and it becomes hard to speak.
