Music of the spheres

Earth is not a quiet planet. It transmits a rather hideous sound [flash] into space that is 10,000 times greater in strength than any man-made radio transmission. The Earth also quietly hums with seismic Love Waves (hear them), while the Magnetosphere is alive will all sorts of sounds (check out the creepy-sounding Chorus Emissions). Also, stars sing out in middle C before they explode as supernovae, and the Perseus Cluster black hole has droned a B-flat for the past 2.5 billion years.
Now before I click on that Perseus Cluster link, is the recording 2.5 billion years long? Because I only have a billion and a half max before my next meeting and I can't be late.

I am way more into B-flat than boring old Middle C.

I just emailed the professor who wrote a paper about the AKR, requesting a long sound clip. I'm gonna make a song with it.

"200 to 400 hertz, in the audible range around middle C"
That'd be a full octave, starting and ending roughly halfway between G and G#.

There is another AKR clip in the Magnetosphere sounds link.

The "rather hideous sound" link starts off with a Dark Knight trailer. Ha ha

Yeah, but without Steve O'Malley and Greg Anderson, who cares? ;)

I think the Earth sound is so hideous is perhaps because our Earth is in alot of pain.

You can hear the sounds without the narrator on this European Space Agency page.
I don't think the sound is so hideous. There are some quite musical things in there.

You're being sarcastic, right? It's a hunk of rock floating about in space. I don't think our planet has performing inter-stellar emo tunes.

There is no sound in space; this is all very silly.
In order to hear this 'sound', you have to convert electromagnetic radiation into a series of compressions and rarefactions in air. The fact that the frequency of the radiation falls into the audible range is coincidental.
Pretty much any batch of data can be manipulated to produce a 'sound'. Maybe you could take some road death statistics and produce something akin to a jolly Irish jig; in other words, any emotional response we have to that sound is just our own creativity at play and gives no insight whatsoever into the original phenomenon.
Cool sounds though.

You know what else about B-flat ...? (Includes reference to the Perseus cluster.)

Try also the "Symphonies of the Planets" series from, now defunct, Laserlight Digital. It's made (somehow or other_ from signals received by the Voyager probes.
I managed to find a couple of these, and though the sound quality is on the hissy side sometimes, this is quite possibly some of the most sublime and trance-inducing ambient music you're likely to hear.

The moon, on the other hand, makes a sound best described as "Bom ba ba bom ba bom ba bom bom ba ba bom ba ba bom ba ba dang a dang dang ba ba ding a dong ding"...

the pitch of the sound generated by the black hole translates into the note of B flat. But, a human would have no chance of hearing this cosmic performance because the note is 57 octaves lower than middle-C.
57 octaves lower, with each octave halving the frequency, would result in an oscillation every 19 million years.
It's a bit of a stretch to call that a B-flat.

Yes, and for billions upon billions of years this has made absolutely no sense. And from very soon now until the end of the world itself, it will be pointless and irrelevant.
But right here, and right now, it all miraculously falls into place. We are living in the most specialest moment in the history of the universe.

In musical terms, the pitch of the sound generated by the black hole translates into the note of B flat. But, a human would have no chance of hearing this cosmic performance because the note is 57 octaves lower than middle-C. For comparison, a typical piano contains only about seven octaves. At a frequency over a million billion times deeper than the limits of human hearing, this is the deepest note ever detected from an object in the Universe.
Aparently the guys at NASA haven't heard the jackass in the Hummer that drives back and forth in front of my house every night just after I get my daughter to bed.

None; they prefer to cry in the dark. *BA-ZIIING!*

That there wavelength is pretty damn long.

No foo! There isn't any sound as we could here it, even if our ears were made of space-resistant material, but it does happen. Unless you consider sound to be only the spectrum of matter waves that the human ear can hear, but then you have to consider other animals, too.
That earth-sound thing is really cool. I wonder if our CFC emissions have altered the sound? And if could listen to the sound of an earth-like extra-solar planet over a long period, could we notice the change and deduce that there was an industrious civilization?

Cowbells aside, one more to add to this collection of cosmic sounds: the primal scream of the first million years of the universe, here.
