Is this true or even possible?

should be, it would have to record the soundwaves from the surroundings and send a inverted soundwave back to neutralize(sp?) the original soundwaves.

I think

Yes, the Japanese have been using the technology in their refrigerators for a whole now, hit one wave with another & the waves break up & dissipate, it's pretty cool.

Same with the noise cancelling headphones.

I'm sure it works on the principle that noise cancelling headphones do - Produce a sound wave exactly opposite the noise you're cancelling & the two waves will interfere with one another & effectively eliminate the noise.

The difference is that noise must travel through the headphones to get to your ears, whereas in a PC you'd have noise generators at different distances from you. While I don't know for sure, I would imagine that unless the device predicted the noise pattern it would be possible for them to be out of sync depending on where you were in relation to them - Which would actually make the situation worse.

I've thought about it before, but while it works for headphones & the like I'd wait & see how it works before I'd buy one.

This is so cool! I sure hope this comes out soon and is effective.

Ok, another question. Would it have to have a certain radius that it would work in. Couldn't it interfere your speakers too? Or even somebody that is talking? :Q

Would the device monitor the sound frequencies and levels inside the computer and compensate what signals are sent out in real time? I would think that a computer makes sounds at different levels and frequencies over time.

Can I get one for a female's voice....?

LOL, you could hide it in a (large) necklace and give it to her as a present.

Married with a daughter.

I've seen car mufflers with this sort of technology.
