...who will answer?
So much for laws against littering. Helium balloons don't stay aloft forever.
Just out of interest, who is putting up the money for this? They sound like they are spending other people's money with no comeback
I personally like calling stupid people to hear the echo of my voice in their empty head.

Hope they turn off the ringtones / vibrators.

But almost scary at the same time. Anyone plan on watching this?

would we get to see cell phones zapped by lightning?
Would that be considered roaming?
It would be interesting to listen to during a storm or tornado.

perhaps you should read the latest slashdot poll
Why cellphones? I mean, really, what's the value of having people call in to hear wind whistling around, balloons rustling (latex/plastic rubbing together), and cellphones ringing.
Why not use higher-fidelity equipment, and make a recording available for download afterwards? I think the quality and value of that model would be much more attractive.
Additionally, there will be issues with either 1) there being too few cellphones to meet the demand, and no one being able to get on them and listen, or 2) there will be too many cellphones, necessary to meed the demand, that will occupy all the access points/lines at the cell tower sites, and interfere with each other due to ambient RF from the phones being packed so close.
I hope these folks are bright enough to have considered and addressed these issues.

How do they answer the phones?
And yes I started to read the article but was t/o/oo/wo lazy t/o/oo/wo click the More Details link.
I can't wait to see how many people mistake this for a UFO. ;-)
What is the point of this?
Answer here
Presumably they will just hear a few wind noises as it blows past the microphones?
I found a pretty good explanation here.
Just out of interest, who is putting up the money for this?
I think if you dig around, you might find out here.
They sound like they are spending other people's money with no comeback
Science had known to occasionally be funded by someone for one reason or another. I would recommend reading this page to learn about the experiment.
Or you could just RTFA.
Well, there's an amazing waste of time and money. But hey, it's their money, not mine.
I'm tempted to call for a minute or two, even if it's an international call. It'll break the monotony of office conversation.
"Ya last night I called a cell phone in England, hanging from a balloon. What did you do?"

Oh! The sky sounds just like a busy signal.
I'm an American. I love this country and the freedoms that we used to have.
I know that we could use a midget, but if you're going to send up a midget, you may as well just send a weather balloon with a microphone. You never think your midget friends are useful until you actually need them :)
Even those who arrange and design shrubberies are under considerable economic stress at this period in history.
It would be interesting to hear the northern lights.

If I whistle through the receiver we should get one hell of a show!
This is all well and good, but I would REALLY like to get a number... NOW (eh, I'm impatient).
I for one welcome our new inevitable bad pickup line overlords.
Imagine a Beowulf cluster of these.
Okay... I'm geeked out. End transmission.
And now, for a sig that's a complete copout.
Cell phones are also optimized to only capture and playback sounds in the human vocal range. They weren't designed to carry any sound outside of that range... and may just discard it as noise.
There's better use for this money than spending it on something that's so...useless. Not even news worthy too.
Think I'll set up a 900 number. For a buck, people can call me to hear me blow air into the microphone.
I wonder if you'll be able to hear people shouting into the other phones. If some phones are close enough, it could turn into an impromptu conference call.
...
Why not use higher-fidelity equipment, and make a recording available for download afterwards?
No, it would be much easier to make a shitload of money using mobile phones. All you need to do is charge a high per minute rate.
Speaking of RF, they don't make clear *how* users are expected to hear these VLF phenomena, considering the GSM handsets popular in the UK are 1. digital (any interesting 'noise' becomes a bit error likely to be discarded from the stream), and 2. UHF/'microwave.'
There's something absurdist and poetic about 'calling the sky,' but I do hope that a) there'll be a VLF radio onboard patched into said phones (erm, and the phones' own RF will indeed play hob with it, to the point it'd be unlikely to hear natural phenomena over the noise), and b) they'll webcast the audio so more than just a select few can 'participate.' (Art can be about exclusivity, but in this case, it adds little to what seems intended as a populist piece.)
---
They've got a lot of pretty sketches and prototypes as apply to hanging the balloons, but no detail on the wireless end at all.
If you RTFA... the only discussion about phones is that people on the ground watching the ballon structure can use their mobile phones to hear what the ballon is hearing... since the whole structure will be teathered to the ground anyway, they could just be using a wired microphone with a really long extention cord to feed the phone system that everybody's going to be dialing into.
Uhm... speakers on the ground might have been a cheaper idea to use...
Mkay...
At least that was MY first thought when I saw this story.

I would say that this is an interesting example of environmental art. A large, temporary display available for anyone to observe. And in this case interactive which is quite interesting. And yet even more interesting is that the observer can become part of the piece as they dial in, causing color changes.?
If you're going to make art, may as well make good art.

Oh my God. Look at how stupid you are! I can't believe you typed that.
I mean, really, what's the value of having people call in to hear wind whistling around, balloons rustling (latex/plastic rubbing together), and cellphones ringing.
Maybe you should read the article first before commenting. It is not just the wind they are interested in. They also 'listen' to radio frequencies.
From the article: Using mobile phones people will be able to listen to the actual sounds up high, the electromagnetic sounds of the sky as well as streams of "whistlers" and "spherics" (atmospheric electromagnetic phenomena that are the audible equivalent of the Northern Lights).Of course, the action of calling the cloud changes the electromagnetic environment inside and causes the balloons to vary in brightness, colour and intensity.
Why doing it the hard way? (You don't have to go 60 m up in the air to get all that.) Well, I suppose that is what Art is all about.
Nyh
Maybe they'll hear the other cell phones ringing... ;)
no cell phones are cheaper...
Hasn't anyone seen that deal on amazon.com where you make $50 to $200 for getting a phone with service plan. I guess after ordering 1000 phones some geek had to figure out what to do with all those phones, and where to waste the $50,000
Weird, all I can hear is 50 ringing phones
Or is this the most dumbass thing I have *ever* read about on /.?!?! And to think of some of my submissions that have been rejected. Jeeeeeeeeeeeeeeeeeeeezus.
Not only that, compression algorithm will get rid of most of the scientifically useful information. Human brain is a wonder, you can't believe how much information you can get out of a DSP'ed audio stream. I do this regularly, with a signal bandwidth of a couple of kiloHerts, you can still understand the conversation. Radio amateurs (like I) do this regularly.
I'd just rent a video.
Wow, with an outlook like that, your life must really suck :P
Actually, they'll probably be hearing the sound of many, many phones ringing...

The FAA also prohibits the use of cell phones due to a possible risk of interference to the airplane navigation systems
This is - and always has - been an absolute crock of bullshit. Their technical objection is to preserve the Airfone monopoly (the credit card phone systems on the back of some seats) - nothing more.
Would you trust your life by flying on a plane who's systems could jammed by a $50 cell phone no bigger than a pack of cards? I think you wouldn't - and I'm sure aerospace electronics engineers would be capable of solving that problem effectively. Let's see - passengers are inside a large metal can - and there's unlimited mounting space for antennas on the outside.. hmmm..
No, you will hear the ringtones of the other cellphones
Do you have no imagination whatsoever? Its ART for cryin' out loud. Its not a scientific experiment.
this is a terrible idea. it's a waste of electronics, money, and pollution to boot.
Very cool. Thanks.
You're probably referring to the Schumann resonance, the resonance of the earth-ionosphere resonant cavity. Energy from lightning around the world excites this resonance, which then rings--much as hitting a bell with a hammer causes the bell to ring.
Also like an acoustic bell, there is a fundamental frequency of resonance and many overtones that grow fainter as you go up in frequency. The fundamental Schumann resonance is approximately 7.8 Hz; the first few overtones are usually given as 13.8, 19.7, 25.7, and 31.7 Hz. There is a slight variation in the frequencies involved over long periods of time, as the ionosphere changes in response to solar activity.
When was the last time they talked about "helium filled (weather-) balloons"?
So this time they're telling us this in advance, so we're prepared when we see a colorfull "thing" flying around you can dail into;
when actually you have an UFO with aliens who're testing their wireless telephone system or something..
Be afraid.. */me searches for his tinfoil hat*
ET phone home...
I think we can keep recursing like this until someone returns 1
...because if they are, the GSM circuitry will detect zero noise and therefore send zero signal to the receiving handset. The receiving handset will auto-generate a random noise which is perceived by our ears as silence.
Thus, if you phone up these balloons, the sound you hear has been generated by the phone you are holding next to your ear!
That's a really low frequency. Is it a concidence that it's wavelength is the almost the same as the circumference of the Earth? Or is that the whole reason it works?
Thanks for the information and links!

Oh come on, read the article. This whole thing is being done as a bit of *fun* combining some interesting science and a big art component. It's meant to appeal to people's sense of wonder and interest them, not to be the most technically adept way of providing a multi-channel audio feed from 60M up. If you had bothered to read the piece you would have seen that, apart from anything else the act of contacting one of the suspended phones is meant to change the RF field in the balloon cloud enough to change the colour of the surrounding balloons change the colour of the light they emit. I live near Greenwich, and I suspect I'll be there, together with a lot of families with picnics having a laugh. And for those people asking about the funding - these people are coughing up: "The Daniel Langlois Foundation'spurpose is to further artistic and scientific knowledge by fostering the meeting of art and science in the field of technologies. " The foundation unfortunately has a terrible liking for bad Flash.
Wouldn't you just be listening to the sounds of everyone elses phones ringing??
Since the atmosphere is only 12 miles high, it is obvious that they must mean a 25 mile net at the depth of 60 meters. The weight of the cellphones needed to fill it probably can't make a bigger crater than that. If it makes a sphere, it has a volume of 3.3E13 m3. Each m3 can probably contain about 5000 cell phones, each weighing in at ~200g. This comes to 1.7E17 cell phones at a total weight of 3.3E16 kg.
I hope they have them all on vibrate, otherwise all you'll hear is ringing :)
-=Hinkey=-
Then get me down!!
According to http://www.lpl.arizona.edu/impacteffects, such a net of cell phones will create an impact of 1.16E9 megatons of TNT and create a crater 108 miles in diameter. It also notes that simliar sized nets of cell phones hit the earth about once every billion years.
What is the point of this? Presumably they will just hear a few wind noises as it blows past the microphones?
Indeed. Conceptual art either wows you -- or is stupid. Maybe I'm wowed by the stupidity of this one.
and there is finally a link between cell phones and head related injuries.
"If any question why we died, Tell them because our fathers lied."
This is clearly not science, it is art. There are no untested hypotheses, there is no rigorous data being collected that may tell us more about EM in a deductive way...
It is no more science than a painting of a cat is a cat. Ceci n'est pas une pipe, right?
This is a moving demonstration of how complex the sky's environment is, and how much we can't see. Since people still have no clue about radiation, it will be a little educational... but mainly it will create an emotional response to an ordinarily invisible phenomenon.
Oh, and the funding is provided by the Daniel Langlois Foundation for Art, Science, and Technology, which ends the discussion about whether it's worth the money. Daniel Langlois thinks art about science is important, and it's his money.
This CELLPHONE event sponsored by AT&T, Sprint, Cingular, etc... (Skytel? Orange in UK?)
Am I cynical, or does this just seem to be a way to get people to burn airtime? I mean, horrible sound

even less useful than a bicycle with square wheels (in the real world, anyway).
I imagine in addition to ringtones you'll hear a lot of tinny voices yelling "Hello!? Hello?!"

Who is liable when these things fall back to Earth?
That's the whole reason it works--the frequency of resonance is a function of the physical size (and shape) of the resonantor, just like in acoustics, where the larger bell has a lower pitch. The frequency of resonance of the earth-ionosphere cavity is largely (but not completely) determined by the circumference of the Earth.
