The worlds quietest room is -9db and it's said that the lack of sound can make you hallucinate. Challenge accepted!
‘When it's quiet, ears will adapt. The quieter the room, the more things you hear. You'll hear your heart beating, sometimes you can hear your lungs, hear your stomach gurgling loudly. ‘In the anechoic chamber, you become the sound.' And this is a very disorientating experience. Mr Orfield explained that it's so disconcerting that sitting down is a must. He said: ‘How you orient yourself is through sounds you hear when you walk. In the anechnoic chamber, you don't have any cues. You take away the perceptual cues that allow you to balance and maneuver. If you're in there for half an hour, you have to be in a chair."
As if an inkjet printer that can print skin wasn't enough, guess what's coming to FOX? Give up? Okay, I'll tell you. COSMOS!
Not only that, but it will be hosted by....*drum roll please*....Neil deGrasse Tyson!
I'm simply giddy with anticipation.

This is kind of science, I suppose. Whatever the process, beautiful result. Enjoy. http://vimeo.com/69633166
My wife does that kind of stuff, and was pretty sad to see that someone beat her to that particular project.

The comet that the ESA recently landed a spacecraft on is apparently emitting subsonic "sounds." How this is possible in a vacuum is not explained. Also they had to process the signal, which is in the range of 40 to 50 milliHertz.

Sure it is:
The comet seems to be emitting a ‘song’ in the form of oscillations in the magnetic field in the comet’s environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased by a factor of about 10,000.
They're not saying it's emitting sounds, but magnetic waves. The sounds are those waves sped up and turned into sound. It's like how your sound card doesn't directly produce sound that you can hear from the wires, but it gets converted to sound waves by your speakers. (You could actually do something similar on Earth by recording the magnetic flux off of your speakers, and then playing THAT signal on another pair of speakers. For bonus points, do it while the first pair of speakers is in a vacuum.)
Anyway, yeah, this is really, really cool. And the big surprise is that it's generating these magnetic waves in the first place. I wonder by what mechanism that happens!

That Zorba the Greek intro was cool. Sounded like Predator.
