Hi all,
there is a new experiment about to start at the Gran Sasso laboratory
(Abruzzo region, central Italy), to detect dark matter (featured on BBC
News24 today). The business end appears to be a metal sphere, loosely
comparable to a bathroom in size, which will soon be filled with argon.
The presenter was able to climb inside to make the report, and the
acoustics are, to say the least, "interesting". Small and presumably
heavily acoustically reactive. I have asked my one particle physicist
contact at Cern to make inquiries about sampling it, if there is time.
Is there anyone in that area able to jump to the challenge at short
notice, ideally with a surround mic? It would have to be a hand-held or
at least compact portable setup, as the access hatch into the sphere is
human sized, but possibly too small to pass large-scale kit. My guess is
that a mic, a laptop and a (small) balloon plus needle may have to do.
The idea being, needless to say, that ~when~ some significant data is
obtained, it can be sonified with an appropriate acoustic context. It
would have to be a labour of love, on the assumption that getting a
research grant for it at such short notice is rather unlikely!
