Ok, now that I've got your attention. . .
Don't worry, this is a question about bose. Actually, a technology that they use.
We've all heard about the $300 bose noise cancelling headphones. Laughed at them, etc. But, the technology got me thinking. I'm guessing this is totally wrong, but here goes.
Supposedly, the noise canceling part works something like this: it "hears" the noise around you, and it produces a wave that is "negative" to it. right? So, that got me thinking. Say there's a steady noise that you want to block out. Something, like, say, an airplane's engines. What if you took a mic, recorded the cabin sound, put it in cooledit, and took the negative?
If you were on an airplane, and played that sound, would the engine sounds be blocked out? I'm sure it wouldn't be as good at canceling as the bose, but would it work? And, on top of that, could you play, say music, or a movie?
Now, I'm SURE this is all wrong. . . anyone?
