Every sound you hear can be described completely (and therefore reproduced exactly) by a set of parameters: volume, timbre, duration, pitch, direction. The way we choose to map the different numbers ... is arbitrary- we can choose any one of those columns to be volume and we can say that even numbers mean loud and odd numbers mean quiet, or we can say that prime numbers are the only ones we can hear, or whatever.
The growing sound library includes the sound of a top quark jet, and the sound of a detector sweep "played" on a synthesized marimba. And in 2010, Asquith and her team produced this stunning video simulating what sounds the Higgs boson would be likely to make when they are produced at the LHC:
"We can hear clear structures in the sound, almost as if they had been composed," Richard Dobson, a composer with the LHCSound project, told BBC News. "They're so dynamic and shifting all the time, it does sound like a lot of the music that you hear in contemporary composition."
Ultimately the goal as as much scientific as artistic, according to Asquith: "onification doesn't just mean turning numbers into sound. We want to make a sound that has some information in it." The hope is that LHCSound's sonification of ATLAS data could be a useful supplement to more traditional methods of data analysis, eventually enabling physicists to detect candidate events by ear.
