That's where the sounds come from indeed - corrosion is bound with creating
voltage cells. That's why, for example, there are banks of metals on ships which
are less (more? I finished my hs chemistry class over three years ago...)
electronegative than what the ship is made out of. Those metals then
create the positive pole with the salty sea water, and it's those banks of metals
which give up to corrode instead of the construction metal in the ship.

That's a good, old safeguard mechanism so ships don't get a hole. After the metal
banks are done with, you can just put new ones in.

So anyways, that's where the voltage comes from. And the amperage?
You can hear the sweeps and zips, but no pops. To remind, it's the amperage
that creates the sound and frequency in electronic music (and amps, like in the
circuit). Comparing this to a normal battery (which just gives nothing, and static
if you move the connected cables around the anode/catode), I guess it all breaks
down to the fact that, as some might know, water is a fluid.
This fluid then allows the positive charges to move as well as negative charges.
This creates impetum forces, which create the sweeps: as positive charges get closer
to the negative charges, resistance lessens, thus amperage increases.


No, you *can't* hear "atoms hitting atoms", and it's not getting amplified.
But electricity resulting from that IS, if that's what you meant, Michael :)



cheers.
