Making Your Room Quiet
el_flynn writes "This may be a cure for those of you with loud computers, or perhaps those who spend lots of time in NOC rooms that generate lots of noise: NewScientist.com mentions about a "Silence Machine" that gets rid of unwanted noise. I want one to quiet down my neighbour's loud dogs. " These are also being tested in cars, to make the car quieter. I've got a pair of the headphones that the article alludes to - they make airplane travel much nicer, and having something like this to cancel machine noise would be excellent.

I don't know about the rest of you guys, but I find it difficult to sleep at night without the whoosh of the fans from the handful of servers I keep in my room. What kind of geek likes quiet machines?
This is not a Fugazi
try breaking your eardrums, then you cant hear diddly.. and its cheaper than buying these 'quiet' solutions!
:-)
I can say myself, I've been deaf since I was born ( I was born deaf ) so I can say that its the easiest solution since I cant hear diddly so all of my computers are supposedly "quiet" for me! Soundproof padding for my room? Nah! dont need it!
Wow, you're almost good enough to be a slashdot editor!
...Wait
Yeah. I agree. And, if you go near the speed of light,
you can slow time and everything will look compressed.
Old technology. So, why don't we do it? Because it's not
easy.
So, there is a noise source producing sound energy and I have a so-called noise cancelling machine producing out-of-phase sound energy.
The end result is no sound, therefore energy has been destroyed.
This violates all the fundamental rules of nature.
I urge you not to build this thing

.45 caliber machine which performs this job adequately...been around for years.
You know, they make a

"Remember when the U.S. had a drug problem, and then we declared a War On Drugs, and now you can't buy drugs anymore?"
perhaps, if it's powerful enough, it could be loud enough to even cancel out the bass vibrations in your neighbor's apartment! he'd have to knock on YOUR door and ask you to turn your noise cancellation device down! :)
The other day I let a friend of mine use my noise cancelling headphones to listen to a CD he just bought. After fiddling with his CD Walkman for a bit, he still wasn't able to hear anything on the headphones. It turned out the CD he bought was N'Sync's greatest hits album, and the headphones were actively cancelling out all the noise from it leaving only the real music (ie silence).
used something like this at a politician's speech
Eliminating bass can be much simpler than that with just an amplifier, speakers, and a... signal generator: position the speakers against the dorm wall where the source originates. Set the amplifier for test purposes at medium volume. Slowly calibrate the signal generator to achieve resonance of the walls. This is determined when picture frames rattle off the walls. Once this point is determined, maximize amplifier output. The resonant energy building within the walls will then be transparently delivered to the client in what can be described as a non-maskable interrupt.
What can be described after that is guaranteed to be silence. Except for breakage of items in the host's bookshelves, etc... Slight profanity may be also side effect. Use with caution and deny any knowledge when questioned.
I wonder if this will stop bass vibrations.

I didn't realize they made that much noise. They're only fish, after all. I suggest staying out of the water.
I watched C-beams glitter in the dark near the Tannhauser gate.
Does anyone ever consider that I might *want* noise? The dorms I live in are so damn loud that I'll do anything to bring the ambient noise above the human- and stereo-created noise threshold.
Right now I've got a non-functional AC unit and dual in-window fans going primarily for this purpose alone. The frige is right next to my bed and since I don't have any money for food, I sometimes leave the door propped open just so the compressor runs and lulls me to sleep. I'm also considering buying a monster box fan to put next to my bed so my frige doesn't have to work so hard. (Or if I actually want to put anything in it.)
And don't get me started on my computer. I think my neighbor can tell when I shut this thing off.
For the curious, I have tried those anti-noise machines and noise-cancelling headphones, but they don't take care of 99% of the problem for me: bass. Until I started working nights, I'd usually be up until the wee hours of the morning because some dipshit wants to have a Jurassic Park marathon with his dipshit buddies. Let me tell you how fun that is when I had to get up a 6AM for work every day.
And yes, I have also tried earplugs, but again, they don't block out the bass... the sound has such a low frequency that it travels through your skull rather than through your ear canal.
Isn't that just like the typical Slashdotter, making things SOOOO much more complicated than needed? If the PCs and equipment in your room are unacceptably loud...
