You can hear sort of a high rate oscillating noise, basically an AC Current cycling really quickly. This is a resonation through the rigid structure of the apparatus. Otherwise, it's pretty quiet, since the plasma is being exhausted into a vacuum chamber.
(Quick physics lesson for those who missed it: Sound waves, as we usually hear them, are actually compressed air waves. Vaccuum means no air, no air means no sound.)

So what you're saying is that if a tree falls in the woods in a vacuum, definitely nobody will hear it...

Vaccuum means no air, no air means no sound.)What does a fission or fusion explosion in space look like? There's only a tiny amount of material to explode, no air to ionize or compress, no water vapor to condense into clouds, etc. It seems like it would just be a tiny point of light. Any ideas?
