BYU Project to Silence Computer Fans
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."
well its no news that as closer you get the speaker to the noise you want to cancel you'll get better results. Its like you have a light bulb and if you want to supress the light, the closer you cover it, the better it will do.

I get how useful it would be to cancel noise in certain situations, but outside of a server (and even my Dell 400SC is sooo quiet I can barely hear it), what is the big deal for the vast majority of applications???
This is why most modern fans have RPM monitors, and most motherboards have built-in support to alarm and/or shutdown when RPM's fall below a certain level. Beyond that, most current CPU's also have temperature sensors, so that if a fan fails, and temperatures begin to rise, the system will either shutdown, or simply halt.
*to rip from a previous post: Yes, but that post was from timothy. This one is from CmdrTaco. Completely different.
Hmmm.
Will this same technology work on my girlfriend. She can be like one of those movies that is better on mute.
Evolution or ID?
