is this possible?? If I have a room with noise is it possible to have noice in one half of the room and silence in the other nutralizing sound waves in the middle of the room?? Have you ever heard of this?? sorry about the english.Brad from Holland
guess its not the room for this subject but I have heard it is possible and they are working on this in China.Just imagen it will change the world
Is it possible? It is sold commercially by Bose. And has been for years. In fact I have a pair of 'em I wear routinely when flying. ~$300 retail.
Let me get this straight you have the ability to nutralise sound (waves) in an open space with sound waves???? for $300 and GE and Telefonica have just pumpt 800 million euros in this project. Are you drunk?? this would and will change the world as we(maybe not you!!) know it
I thought it would be interesting to have such headphones for a dentist's drill, to cancel the screaming whine. The required sampling rate is too high. I tried disposable foam ballistic earplugs and they work quite well - you can then clearly hear the tooth being ground away. It's not an improvement.
DA Morgan I hope you are happy with your "really spongy earbuds" but that was not the question. Could you please answer if you think it is possible or not and your reasons.
DA Morgan try
www.school-for-champions.com/science/noise_cancellation.htm some resources but no answer to my question.
Is it possible to have noise in one half of the room and no noise in the other half of the same room using or placing a piezoelectric devices?
(cancellation in air)
