BYU Project to Silence Computer Fans

Posted by CmdrTaco on from the anti-noise-is-nifty dept.

phunster writes "The New York Times has an article about Scott D. Sommerfeldt and his students at BYU who have created a noise suppression system for computer fans (drop of human blood required to read article). The technology is not new, he uses out of phase sound to substantially cancel out the sound of the fan. What is interesting is his implementation of the technique. While other systems place a microphone and speakers in the center of a room, he places four miniature speakers and microphones around the noise source itself. His results are promising."

    Let's not get the cart in front of the horse here, and for those non-USA people, that means "Let's get things in the proper order".
    Perhaps one day the people in those backwards nations will have "carts" and "horses" for themselves, and the wisdom to understand which goes first, so they can appreciate our American sayings. We can only hope.
