I've been looking up more videos of plasma speakers and electric discharges. There are 3 things that I'm finding quite interesting:
First, both the roaring sounds and the electrical arcs tend to have their frequency spectrum gradually decline until a certain point where they drop
off suddenly (that is, both look like a gradual slope leading to a cliff that drops off at some high frequency).
Second, both also tend to be a variable spread of frequencies save for 3 or 4 obvious peaks. The only difference here is the frequency of those peaks.
For small electrical arcs, the peaks are higher, producing a higher-pitch sound. For large arcs (such as lightning), the peaks are lower because a
greater volume of air is displaced, producing a lower-pitch sound.
And, third, the location of the "cliff" seems to be relative to the location of the peaks. A lower-pitch sound (the roaring) has a lower drop-off
point, whereas a higher-pitch sound (the smaller arc) has a higher drop-off point.
It's amazing, really, how similar the frequency spread of the sounds are to that of the smaller electrical arcs - the only difference being their
pitch (again, attributable to the difference in size).
I do want to point out, though, that the fracking sounds are also very similar. They could certainly be it, given that the sounds your hearing, then,
would be more of a reflection off the cloud cover, which would no doubt alter the sound somewhat. I would probably consider that the most likely
possibility at the moment.
