Anti-snore silence-bomb

 A device which silences the snores of a snorer

Call it "The silent snorer" it sends soundwaves that "oppose" the sound and create silence, (see the Lauralee link...) so that you don't hear the snores.

I could see military uses, as well as many families saved.

I actually worked on a noise canceling project at IBM Haifa Research Lab.

       In what sense is this a bomb? You could drop it on the person's head, and then you wouldn't need fancy electronics. Or is it covered in meringue?

       It's in the NOISE CANCELING category, and I didn't find anyone who talked about snoring.   

       It's not really a "bomb" but could be used as a "weapon". "Silence bomb" is a known term for this technology. It works by sending waves very close to the original ones, but at a different phase, opposing the original ones, and canceling the sound effect.   

       If you want to understand the phenomenon, imagine you make waves in your bathtub and have a way to "check" these in your bathtub and make "anti-waves" so that when ever the wave water should be going up there's a "down" part of the new wave canceling it. The result is an almost completely calm bathtub.   

       A better explanation is at the Lauralee link.   

       Actally I'm surprised this idea received fishbones, and am going to try and make it work and sell it.
