IOW, they are making it up out of whole cloth, in order to placate some, and attempt to show something coming out of the $6 billion price tag.
This isn't science. It's silly.
No they are not "making it up". They admit freely that this is what they expect, based on simulations constructed according to the current theories. They have not yet gotten any real data, and did expect to have at this point. If the theories are incorrect, it may "sound" considerably different, or they may find something entirely different than the Higgs boson is predicted to be.
They needed to do the simulations anyway, so running the simulated data through this audioliser system, they get to test it as well.
